Description

switch

technical field

The present invention relates to a switch for turning on/off electric power supplied from a commercial power supply to a load; and, in particular, to a switch to which electric power needs to be supplied.

Background technique

As for a conventional switch for turning on/off power supplied from a commercial power source to a load, other than a switch for switching a mechanical contact inserted in a power feeder (power line) from a commercial power source to a load, developed There is proposed another switch in which a semiconductor switching device such as a thyristor, a triac, etc. is inserted into a power feeder and is turned on/off (on/off) by using a circuit cut off) the semiconductor switching device. In the case of the former switch, the contacts are mechanically opened/closed by a handle manually operated by the user, and therefore, there is no need to supply power to the switch. On the other hand, in the case of the latter switch, when a user operates an operating handle, a circuit drives a semiconductor switching device, and thus, the switch requires a power source for operating the circuit. Therefore, while a two-wire line is sufficient for the former switch, a three- or four-wire line is required for the latter switch.

The present applicant has proposed a switch using a semiconductor switching device, which can be operated with only two wires, thus reducing the wiring cost (see, for example, Japanese Patent Laid-Open Application No. 2001-227804, paragraph 0021 to 0026 and FIG. 7, which will be referred to as reference 1 hereinafter. FIG. 35 shows a circuit diagram of a conventional switch disclosed in Reference 1. As shown in FIG. In this switch, an overvoltage absorber such as ZNR and a smoothing capacitor C1 are respectively connected between connection terminals Ta and Tb that connect the commercial AC power supply AC in series with a load L (for example, a ventilation fan), Furthermore, the triac TRC is connected thereto via a filter inductor L1. A parallel pair of resistor R1 and capacitor C2 is connected between the T2 and T1 terminals of the triac TRC via a rectifier DB comprising a diode bridge. Here, the parallel pair of resistor R1 and capacitor C2 is connected between the gate G and T2 terminals of the triac TRC. If the triac TRC is turned on, the ventilation fan L is connected to the commercial AC power source AC via the triac TRC and the inductor L1, thereby driving the ventilation fan L.

A second power supply unit 101 comprising a resistor R2 and a Zener diode ZD1 is connected to the DC output terminal of the rectifier DB. The DC voltage obtained by the Zener diode ZD1 is lowered and then stabilized at, for example, 3V by the three-terminal regulator IC 102. The stabilized voltage is supplied as an operation source voltage of the control unit 103 including a microcomputer.

In addition, a thyristor SCR for turning on the triac TRC is connected between a plurality of DC output terminals of the rectifier DB, and a pair of parallel resistor R3 and capacitor C3. The emitter of the PNP transistor Q1 is connected to the anode of the thyristor SCR, wherein a pair of parallel resistor R4 and capacitor C4 are connected between the base and emitter of the PNP transistor Q1. Furthermore, the collector of transistor Q1 is connected to the gate of thyristor SCR via zener diode ZD2 and is also connected to the voltage input of three-terminal regulator IC 102 via diode D1. Furthermore, the base of transistor Q1 is connected to the collector of NPN transistor Q2 via resistor R5. The emitter of transistor Q2 is connected to "ground" of the circuit, and the base of transistor Q2 is connected to the control output of control unit 103 . Here, the third power supply unit 104 includes a transistor Q1, resistors R4 and R5, a diode D1, and a Zener diode ZD2. In addition, the load switch unit 105 includes a triac TRC and a pair of parallel resistors R1 and capacitor C2; the drive circuit 106 includes a thyristor SCR and a pair of parallel resistors R3 and capacitor C3; and, the first The power supply unit 107 includes a three-terminal regulator IC 102 and capacitors C5 and C6.

Here, if the signal level of the control output terminal of the control unit 103 goes low, the transistor Q2 is turned off. If the transistor Q2 is turned off, the transistor Q1 is also turned off, and therefore, the power stabilized by the Zener diode ZD1 and then filtered by the filter capacitor C0 is supplied from the second power supply unit 101 to the three terminals in the first power supply unit 107 Regulator IC 102. At this time, since sufficient current for turning on the triac TRC does not flow to the gate of the triac TRC, the triac TRC is set is an off state, and further, the power supplied to the ventilation fan L is cut off.

On the other hand, if the signal level of the control output terminal of the control unit 103 becomes high, the transistor Q2 is turned on. If the transistor Q2 is turned on, the transistor Q1 is also turned on, and thus, power is supplied to the three-terminal regulator IC 102 in the first power supply unit 107 via the third power supply unit 104. Then, the three-terminal regulator IC 102 generates, for example, operating power for the control unit 103 or the like. At this time, if the cathode voltage of the Zener diode ZD2 in the third power supply unit 104 becomes higher than the breakdown voltage, the reverse current flows to the Zener diode ZD2, and then, flows to the gate in the drive circuit 106 via the Zener diode ZD2. The gate of the flow tube SCR, so that the thyristor SCR has conductivity. If the thyristor SCR becomes conductive, the current required to turn on the gate of the triac TRC flows every half cycle of the commercial AC power supply AC. As a result, the triac TRC is turned on, whereby electric power is supplied to the ventilation fan L. As shown in FIG.

As shown in FIG. 36, after the source voltage Vac of the commercial AC power supply AC crosses the zero-crossing point t0, power is supplied from the second power supply unit 101 to the first power supply unit 107 until the source voltage Vac of the commercial AC power supply _AC reaches the point t1, at which point the source voltage V _AC exceeds a specified voltage, ie, the Zener voltage V _ZD2 of the Zener diode ZD2 in the third power supply unit 104 . When the source voltage V _AC exceeds the zener voltage V _ZD2 , the thyristor SCR in the driving circuit 106 is turned on, and the triac TRC in the load switching unit 105 is also turned on, thereby starting to supply power to the fan L, and, at the same time, power supply from the third power supply unit 104 to the first power supply unit 107 starts. Here, in order to reduce the influence on the load of the diversion of part of the power from the load (ventilation fan L) to, for example, the operating power of the control unit 103, it is preferable to lower the Zener voltage V _ZD2 so that when the triac TRC is turned on , the period Tx from the zero-crossing point t0 to point t1 is shortened. Thus, in the conventional circuit, the output voltage of the third power supply unit 104, that is, the Zener voltage V _ZD2 of the Zener diode ZD2, is set lower than the output voltage of the second power supply unit 101, that is, the Zener diode Zener voltage V _ZD1 of ZD1.

However, in the conventional example disclosed in Reference 1, especially in the case where the load is an inverter-type fluorescent lighting device, the lighting device may be functionally broken, or flicker may occur when the lamp is turned off. That is, if as described above, the output voltage of the third power supply unit 104 (the Zener voltage V ZD2 of the Zener diode ZD2 ) is set lower than the output voltage of the second power supply unit 101 (the Zener voltage V _ZD2 of the Zener diode ZD1 ). nanovoltage V _ZD1 ), then, when the lamp is turned off, when the third power supply unit 104 is replaced by the second power supply unit 101 as the power supply of the first power supply unit 107, the charging current flows into the input terminal connected to the first power supply unit 107 filter capacitor C0. At this time, the current temporarily increases and the impedance of the second power supply unit 101 decreases, so the voltage applied to the load becomes higher than the load voltage obtained when the lamp is turned off. However, if the load is the ventilation fan L, no serious adverse effects will occur. However, if the load is an inverter-type fluorescent lighting device with an electronic ballast inside, where the lamp of the lighting device is turned on once the input voltage of the lighting device reaches the operating voltage of the electronic ballast, it will cause the lighting device to flicker, A phenomenon known as flickering or flashing. Furthermore, among inverter type fluorescent lighting devices, there is a lighting device that continuously monitors an input voltage and responds to on/off transitions of the input voltage by manipulating a switch for a predetermined short period of time. to change its lighting mode (for example, from full lighting mode to dim lighting mode). However, when changing the off/on state within a short period of time by using a conventional switch, the above-mentioned operation is slowed down, or fails entirely, since the voltage input to the lighting device does not drop.

Detailed ways

Hereinafter, a case where an inverter type fluorescent lighting device is used as a load will be described in detail with reference to the accompanying drawings. However, the technical idea of the present invention can be applied to any type of load without being limited to an inverter type fluorescent lighting device.

Example 1

FIG. 1 is a circuit diagram of a switch according to Embodiment 1. FIG. Its basic configuration and operation are the same as those of the conventional example shown in FIG. 35 . Accordingly, the same parts will be assigned the same reference numerals, and descriptions thereof will be omitted.

Contrary to the conventional example, this embodiment is characterized in that the output voltage of the second power supply unit 101 (Zener voltage V _ZD1 of the Zener diode ZD1 ) is set to be lower than or equal to the output voltage of the third power supply unit 104 (Zener voltage V ZD1 ). Zener voltage V _ZD2 of nanodiode ZD2). In addition, although not shown in FIG. 1 , control switches including tact switches and the like are connected to the control unit 103 . Therefore, whenever the control switch is operated, the control unit 103 controls the load switch unit 105, thereby turning on/off the power supplied to the load L from the commercial alternating current power supply AC.

If the output voltage of the second power supply unit 101 is set higher than the output voltage of the third power supply unit 104, as in the conventional example, then, during the light-off operation, the third power supply is replaced by the second power supply unit 101 When the unit 104 is used as the power source of the first power supply unit 107 , the charging current will flow into the filter capacitor C0 connected to the input terminal of the first power supply unit 107 . In contrast, in the present embodiment, the output voltage of the second power supply unit 101 is set to be lower than or equal to the output voltage of the third power supply unit 104 . Therefore, when the second power supply unit 101 is used instead of the third power supply unit 104 as the power source of the first power supply unit 107 during the lamp-off operation, the charging current does not flow into the filter capacitor C0, and furthermore, the impedance of the second power supply unit 101 is not reduced, thereby preventing unnecessary excessive voltage from being applied to the load L. Therefore, provided that the load L is an inverter type fluorescent lighting device having an electronic ballast therein, the flickering light of the lighting device called flicker or flicker and which causes irritation in conventional examples can be prevented. Furthermore, provided an inverter-type fluorescent lighting device that continuously monitors the input voltage responds to on/off transitions of the input voltage by operating the switch for a predetermined short period of time to change the lighting mode (e.g., from full to dark). lighting), then even when the off/on transition is very fast, the voltage input to the lighting device can be reduced, thereby preventing the above operation from slowing down or failing.

Example 2

FIG. 2 illustrates a circuit diagram of a switch according to Embodiment 2. FIG. Its basic configuration and operation are the same as those of Embodiment 1. Accordingly, the same parts will be assigned the same reference numerals, and descriptions thereof will be omitted.

The features of the present embodiment are as follows: the second power supply unit 101 has an impedance element Z2, which is inserted into the cathode of the Zener diode ZD1 and the input terminal of the first power supply unit 107 (the voltage of the filter capacitor C0 is higher); the third power supply unit 104 There is a zener diode ZD2 whose zener voltage V _ZD2 is set lower than the zener voltage of the zener diode ZD1 in the second power supply unit 101; and the impedance of the impedance element Z2 is set so that the second power supply unit 101 The output voltage of the zener diode ZD1 , that is, the difference between the zener voltage V _ZD1 of the zener diode ZD1 and the voltage drop in the impedance element Z2 is lower than or equal to the output voltage of the third power supply unit 104 . Here, preferably, the impedance element Z2 is an element like a resistor or a diode in which a voltage drop occurs through conductance.

In addition, the voltage drop in the impedance element Z2 causes a drop in the output voltage of the second power supply unit 101, whereby the Zener voltage V _ZD1 of the Zener diode ZD1 can be made relatively high. Therefore, it is possible to reduce the Zener current required to obtain a stable Zener voltage V _ZD1 in the Zener diode ZD1 . That is, in the Zener diode, as shown in FIG. 3 , in the case of a low voltage range where faults caused by tunneling effects dominate, a relatively large amount of Zener current is required to obtain a stable Zener voltage. In contrast, in the case of high voltage ranges where the avalanche effect dominates, a very small amount of Zener current can be utilized to obtain a stable Zener voltage. Therefore, by using a Zener diode with a relatively high Zener voltage as the Zener diode ZD1 in the second power supply unit 101 , the power consumption of the second power supply unit 101 can be reduced. For example, if a Zener voltage having a rated voltage of about 5.6V is used, a stable voltage can be obtained using a Zener current of about 10 μA.

Likewise, the advantage of this embodiment over Embodiment 1 is that the power consumption of the second power supply unit 101 can be reduced by only adding an inexpensive impedance element Z2.

Example 3

FIG. 4 provides a circuit diagram of a switch according to Embodiment 3. FIG. Its basic configuration and operation are the same as those of Embodiment 1. Accordingly, the same parts are given the same reference numerals, and descriptions thereof are omitted.

The second power supply unit 101 in this embodiment is characterized in that it includes a current limiting resistor R2; a transistor Q3, wherein the cathode of the Zener diode ZD1 is connected to the base of the transistor Q3, and one end of the current limiting resistor R2 is connected to to the collector of the transistor Q3; and an impedance element Z2 inserted between the emitter of the transistor Q3 and the input terminal of the first power supply unit 107 (the higher voltage terminal of the filter capacitor C0). In addition, a bias resistor R6 is connected between the base and collector of the transistor Q3.

Impedance conversion is performed by the transistor Q3, the base of which is grounded via the Zener diode ZD1, whereby the output voltage of the second power supply unit 101 can be kept nearly constant. Therefore, the restriction on the load L connected to the commercial alternating current power supply AC is relaxed, so that more types of loads can be used. Furthermore, if the impedance element Z2 is not interposed between the emitter of the transistor Q3 and the smoothing capacitor C0 as shown in FIG. 5A, a large amount of inrush current will be caused when the commercial AC power supply AC is initially applied, as depicted in FIG. 5B like that. However, if impedance element Z2 is interposed therebetween as shown in FIG. 5C, inrush current can be considerably suppressed by impedance conversion performed by transistor Q3 and limitation of current flowing through impedance element Z2, as shown in FIG. 5D.

Example 4

Embodiment 4 will be described with reference to FIGS. 6 to 19B. This embodiment mainly includes: a switch main body 1, which includes a main body 2 and a cover 3; a piano handle 4, which is pivotally attached to the switch main body 1; a light receiving cover 5, which is attached to one side of the piano handle 4; a wireless remote control 6, which is detachably attached to the piano handle 4; and two printed circuit boards 7 contained in the switch main body 1.

First, the circuit configuration according to the present embodiment will be described with reference to FIGS. 17 and 18 . FIG. 17 shows a circuit diagram showing the circuit configuration of the switch main body 1 , and FIG. 18 illustrates a circuit diagram of the circuit configuration of the wireless remote controller 6 .

As depicted in FIG. 17, the switch main body 1 includes a control switch SW1 including a tact switch; a receiving unit 108 having a light receiving module 72a (shown in FIG. 8 ) including a light receiving device such as a photodiode or the like, for receiving a transition signal transmitted as an optical signal (wireless signal) such as infrared rays from the wireless remote controller 6; a display unit 109 having a light emitting diode LD1 that emits light by using power supplied from the first power supply unit 107, When the load L stops, the display unit 109 turns on the light emitting diode LD1 through the control unit 103 to display the position; and the changeover switch SW2 is used for channel change, which will be described later. Since other structures and operations are the same as those of Embodiment 3, their descriptions will be omitted.

Meanwhile, as shown in FIG. 18 , the circuit housed in the wireless remote controller 6 includes: a control circuit unit 80 including a microcomputer for generating a circuit for turning on/off the load in response to an operation input of the control switch SW3; A control signal of L; a light emitting diode LD2 for transmitting a converted signal as a wireless signal in the form of an optical signal such as infrared rays; a transmission circuit unit 81 for transmitting by driving the light emitting diode LD2 in response to a control signal of the control circuit unit 80 conversion signal; and a power circuit unit 82 for supplying power to the control circuit unit 80 and the transmission circuit unit 81 using the battery B (for example, a button battery) as its power source. In addition, SW4 in FIG. 18 indicates a changeover switch for channel changeover.

If the control switch SW3 of the wireless remote controller 6 is pressed, an operation signal of the control switch SW3 is input to the control circuit unit 80, and then the control circuit unit 80 generates a control signal in response to the operation signal. Further, the transmission circuit unit 81 drives the light emitting diode LD2 in response to a control signal of the control circuit unit 80, and then transmits a converted signal for the load L as a wireless signal in the form of an optical signal such as infrared rays. Meanwhile, in the internal circuit of the switch main body 1, the control unit 103 monitors the signal input from the receiving unit 108 and the operation signal input from the control switch SW1. If a conversion signal received by the receiving unit 108 is input to the circuit or an operation signal is input to the circuit through the pressed control switch SW1, on/off for flipping the transistor Q2 is generated in response to the conversion signal and the operation signal. State control signal. Thereafter, the drive circuit 106 drives the load switch unit 105 based on such a control signal, thereby turning on/off the electric power supplied to the load L from the commercial AC power supply AC. Furthermore, when the power supplied to the load L is cut off, the control unit 103 turns on the light emitting diode LD1 by applying a voltage thereto, thereby displaying the position. However, when power is supplied to the load L from the commercial alternating current power supply AC by turning off the load switching unit 105 , it is possible to display the operating state of the load L by turning on the light emitting diode LD1 . At this time, as shown in FIG. 19B , the control unit 103 divides the voltage applied to the light emitting diode 1d1 based on time, thereby performing dynamic lighting of the light emitting diode LD1 . Therefore, its power consumption can be reduced as compared with the case where the voltage is constantly applied (as shown in FIG. 19A ). In addition, the conversion signal transmitted from the wireless remote controller 6 as a wireless signal contains data on a channel set by the conversion switch SW4. Only when the channel set by the changeover switch SW4 is the same as its own channel set by the changeover switch SW2, the control unit 103 allows the reception of the changeover signal from the wireless remote controller 6.

Although the switch main body 1 according to the present embodiment has been described, it includes an ON/OFF changeover for responding to the load L in addition to the first power supply unit 107 for generating the operating power of the control unit 103 or the receiving unit 108. The second and third power supply units 101 and 104 that generate the operating power of the first power supply unit 107 can also provide a circuit configuration in which, for example, only a single power supply unit generates operating power for the control unit 103 or the receiving unit 108 . However, in the case of a circuit configuration in which only a single power supply unit generates operating power, it is necessary to generate a voltage larger than sufficient for the maximum power consumption of the control unit 103 or the receiving unit 108 . Thus, the time period Tx from the zero-crossing point to the time point when the triac TRC in the load switching unit 105 is turned on is lengthened, thereby causing the load L to be subjected to the load L supplied to the load L by a part A stronger influence of the conversion of electric power to the operating power of the control unit 103 or the receiving unit 108 . In particular, in the case of setting the receiving unit 108 and the control unit 103 as the load of the first power supply unit 107 as in the present embodiment, the influence on the load L is also greater. On the contrary, in the circuit configuration according to the present embodiment, the time period Tx can be made shorter as the power consumption of the control unit 103 or the receiving unit 108, in which the power supplied to the control unit 103 and the receiving unit 108 is changed from The first power supply unit 107 provides, as described above, for this reason, compared with the above-mentioned case where only the operating power of the control unit 103 or the reception unit 108 is generated by a separate power supply unit, the control unit 103 or the reception unit 108 can be reduced. The power consumption of 108, the time period Tx during which the power supplied to the load L is cut off can be shortened, and therefore, any adverse influence on the load L can be reduced compared with the above-mentioned case using the alternative circuit configuration. Furthermore, in the present embodiment, as in Embodiment 1, the output voltage of the second power supply unit 101 is set to be lower than or equal to the output voltage of the third power supply unit 104 . Therefore, if the load L is an inverter type fluorescent lighting device having an electronic ballast therein, it is possible to prevent flickering of the lighting device, which is also called flicker or flicker, and causes irritation in conventional examples. Furthermore, if an inverter-type fluorescent lighting device changes its lighting mode in response to on/off transitions of the input voltage, since the voltage input to the lighting device is reduced even when the off/on switching is performed quickly, Therefore, the aforementioned operation can be prevented from being slowed down or completely failed.

The front surface of the housing 40 is formed as a curved surface in which the transverse central portion protrudes forward more than the two side portions, and the overall shape of the housing is an arc top. A connecting plate 46 for connecting the rear peripheral areas of the two side walls is formed as a unified whole with the lower part of the casing 40 . Furthermore, the printed circuit board 41 and the iron plate 44 are accommodated in a suitable recess 40 a surrounded by the upper wall and two side walls of the housing and the connection plate 46 . Furthermore, the space enclosed by the front wall and the two side walls of the case 40 and the connection plate 46 serves as an insertion opening for insertion of the battery holder 43 . A suitable recessed portion 40b for accommodating therein the rear portion of the battery holder 43 inserted through the insertion opening is formed at a lower portion of the connection plate 46 . In addition, engaging recessed portions 57 to be engaged with the positioning rib 38 (the upper end portion and the lower end portion formed on one side surface of the protruding table 25 ) are formed at the upper and lower portions of one of the two side walls along the housing. The longitudinal direction of 40 is formed such that when the wireless remote controller 6 is attached to the piano handle 4 , the housing 40 faces one side of the protruding table 25 . In addition, when the wireless remote controller 6 is detached, a protruding portion 59 to be engaged with the user's hand is protrudingly formed on the side wall opposite to the protruding table 25 in the vertical direction. In addition, a fitting groove 40 c to be tightly fitted to the protrusion 37 is formed at a portion facing the protrusion 37 of the piano handle 4 in the edge region of the rear portion of the side wall of the housing 40 . In addition, a protrusion 58 for displaying an operation position is protrudingly formed near the back of the fitting groove 40 c on the front surface of the housing 40 .

On the other hand, the battery holder 43 is made of synthetic resin, and includes a battery supporting portion 47 having a bottom wall 47a and a side wall 47b. In contact, the battery B is formed by, for example, a button battery, and when viewed from the front of the edge portion of the bottom wall 47a, the side wall 47b is approximately C-shaped; unified; and the fitting portion 49, which is connected to the peripheral surface of the side wall 47b, which is unified with the curved part 49a. A recessed engaging portion 48a is formed on the surface of the base 48, which will engage a fingernail when the bracket is detached. Furthermore, an elastic engaging plate 48b is protrudingly formed at the end portion of the side opposite to the fitting portion 49 in the bottom 48 , and the elastic engaging plate 48b has a protrusion 48c at its front end portion to be engaged with the engaging recessed portion 55 of the housing 40 . In addition, a separation groove 49b to be engaged with a fingernail is formed on the rear surface and the bottom surface of the fitting portion 49, and an engaging protrusion 49c is formed on the surface facing the side wall of the housing 40 to be engaged with the engaging recessed portion 56 on the side wall. join.

The printed circuit board 41 has the shape of a rectangular flat plate. Furthermore, when the printed circuit board 41 is attached to the piano handle 4 , a rectangular recessed portion 41 a for accommodating the iron plate 44 is formed at a portion facing the permanent magnet 8 . In addition, circuit elements or contact spring plates (not shown) forming the above-described control circuit unit 80, transmission circuit unit 81, and power circuit unit 82 are mounted on the element mounting surface of the printed circuit board 41, and they are respectively connected to the battery holder 43. The positive (anode) and negative (cathode) terminals of a supported coin cell. When the handle 45 covers the changeover switch SW4 including the slide switch, the printed circuit board 41 and the iron plate 44 are accommodated in a suitable recessed portion 40a of the casing 40, and the light emitting diode LD2 mounted on the printed circuit board 41 is positioned such that It faces the opening 53 of the upper wall of the housing 40 and exposes the operating portion 45 a of the handle 45 through the opening 54 at the side wall of the housing 40 .

A soft (deformable) thin plate 42 in the shape of a flat plate made of synthetic resin is attached to the surface of the printed circuit board 41 . The opening of the case 40 is blocked by a thin plate 42 . A groove 42c is formed on a portion of the side edge of the thin plate 42 facing the fitting groove 40c. In addition, an operable convex portion 42 a protruding in a dome shape is formed on the upper portion of the surface of the thin plate 42 . The conductive portion 42b is formed by applying conductive ink on the circular area of the back of the operable raised portion 42a. Simultaneously, a pair of contact portions 50a and 50b are formed by printing carbon paste on the portion of the printed circuit board facing the conductive portion 42b, which have comb patterns engageable with each other with approximately regular intervals therebetween. The control switch SW3 described above includes contact portions 50a and 50b, and a conductive portion 42b. Compared with the case of using a conventional switch (such as a tact switch, etc.), the wireless remote controller 6 can be made smaller, and the cost can be reduced. Furthermore, if the operable raised portion 42a formed on the thin plate 42 to operate the remote controller 6 is pressed, the thin plate 42 is bent so that the conductive portion 42b comes into contact with the contact portions 50a and 50b. Then, between the contact portions 50 a and 50 b becomes conductive via the conductive portion 42 b, thereby applying operation input power to the control circuit unit 80 . In addition, the transmission circuit unit 81 transmits a conversion instruction as a wireless signal by driving the light emitting diode LD2 in response to a control signal of the control circuit unit 80 .

In order to assemble the wireless remote controller 6, preferably, the handle 45 covering the changeover switch SW4, the printed circuit board 41 and the iron plate 44 are inserted into a suitable recess 40a of the casing 40, and then, through the opening of the casing 40, the thin plate 42 is attached get there. The remote control unit body includes a housing 40 and a thin plate 42 . In addition, if the battery holder 43 having the button battery therein is inserted in the correct direction from the insertion opening, the protrusion 48c of the elastic engaging plate 48b and the engaging protrusion 49c of the fitting portion 49 engage with the engaging recessed portions 55 and 56 of the housing, respectively, thereby This attaches the battery holder 43 to the housing 40 . In order to separate the battery holder 43 therefrom, preferably, fingernails will be engaged with the separation groove 49b formed in the fitting portion 49 of the battery holder 43, and by bending the bent part, the engaging protrusion 49c and the engaging recessed portion 56 will be loosened. joints between. Thus, the battery holder 43 can be taken out by engaging a fingernail with the concave engaging portion 48a.

The wireless remote controller 6 is attached to the engagement part 26 of the piano handle. That is, when the wireless remote controller 6 and the piano handle 4 are connected, if the wireless remote controller 6 is attached to the front face of the engaging part 26 of the piano handle 4, the iron plate 44 accommodated in the housing 40 of the wireless remote controller 6 Attracted by the permanent magnet 8 attached to the piano handle 4 , thereby attaching the wireless remote controller 6 to the piano handle 4 . At this time, the engaging recessed portion 57 of the housing 40 of the wireless remote controller 6 engages with the positioning rib 38 of the piano handle 4 and at the same time, engages the protrusion 37 of the piano handle 4 with the fitting groove 40c of the housing 40 . Thus, the wireless remote control 6 is positioned relative to the piano handle 4 so that the wireless remote control 6 is generally not misaligned. In addition, at this time, if the operable portion (protrusion 58) on the front surface of the wireless remote controller 6 is pressed, the pressure of the wireless remote controller 6 is applied to the piano handle 4, whereby the piano handle 4 is pressed against the axial portion 16. and furthermore, by pressing the protrusion 39 of the back of the piano handle 4, the push-down button 51 of the control switch SW1 is pressed. Thereafter, if the pressing force of the operation portion of the wireless remote controller 6 is released, the wireless controller is activated by the restoring force generated in the push-down button 51 of the control switch SW1 and the restoring force generated in the shaft support spring 24 and the elastic spring plate 18. The remote controller 6 (piano handle 4) returns to its original position.

On the other hand, in order to separate the wireless remote controller 6 from the piano handle 4 for remote control, the housing 40 should be pulled forward by engaging the hand with the protruding portion 59 formed in the housing 40 of the wireless remote controller 6 . In this way, the case can be easily detached, and then, remote control can be performed.

In this embodiment, the thin engaging part 26 is located on the front of the piano handle 4 . Since the wireless remote controller 6 is attached to the engaging member 26, it is possible to make it protrude from the wall surface of the wireless remote controller 6 at least. In addition, because the thickness of the engaging member 26 is small (about 0.5 mm), the distance between the permanent magnet 8 attached to the piano handle 4 and the iron plate 44 serving as an anchor portion accommodated in the wireless remote controller 6 can be shortened. distance. As a result, the adhesive strength of the wireless remote controller 6 by magnetic force can be increased.

Furthermore, since the portion of the piano grip 4 to which the wireless remote controller 6 is attached is made thin, one end of the piano grip 4 may become bent due to external force generated during resin molding. However, in the present embodiment, a tapered surface 4a is formed on the end (right end portion) opposite to the pivot support portion on the back of the piano handle 4, wherein the tapered surface 4a is inclined so that As the distance of the center portion in the vertical direction increases towards either side, the distance between this surface and the front face of the cover 3 increases. Therefore, although both sides of the piano handle 4 become curved, the gap (stroke) between the back of the piano handle 4 and the front of the cover 3 ensures that the two sides close to the piano handle 4 side, and the switch can be operated by pressing both sides of the piano handle 4. Furthermore, an elastic spring plate 18 is formed integrally with the cover 3 for pressing forward the upper and lower side portions of the portion opposite to the pivot support portion on the back of the piano handle. Since the elastic spring plate 18 presses forward the upper and lower side portions of the portion opposite to the pivot support portion in the piano handle, even if both sides of the piano handle 4 are bent, the back of the piano handle 4 A clearance (stroke) from the front of the cover 3 can also be ensured close to both sides of the piano handle 4 , and the switch can be operated by pressing both sides of the piano handle 4 .

The housing 40 of the wireless remote controller 6 has a rectangular parallelepiped shape. That is, the two side walls opposite in the direction of the smaller width are attached to the front face of the piano handle 4 so that they are approximately parallel to the two sides of the handle 4 opposite in the direction of the shorter width. In addition, the front of the housing 40 is formed in a curved shape in which a central portion thereof protrudes forward compared to both side portions thereof, so that operations can be easily performed. Since the side portion of the case 40 is thinner than its center portion, if one of the two side walls opposite in the direction of the smaller width of the case 40 forms an insertion opening for freely inserting and extracting the battery holder 43, Then the thickness of both sides of the case 40 increases, and the battery holder 43 has therein a button battery for supplying operation power to the internal circuit. Therefore, it becomes more protruded from the wall surface, and, of the two side walls opposite in the direction of its longer width, the side wall in which the light emitting diode LD2 is installed cannot accommodate the battery due to the light emitting diode LD2. . However, in the present embodiment, the light-emitting diode LD2 is mounted on one of the two side walls (the upper one) opposite in the direction of the longer width of the housing 40; ) forms an insertion opening of the battery holder 43; and the battery holder 43 is located at the central portion of the smaller width of the case 40 (which is the thickest). Therefore, the housing 40 (wireless remote controller 6 ) can be made thin and protrude less from the wall surface, whereby consistency in design with other wiring devices can be achieved.

In the present embodiment, the attachment unit for coupling the wireless remote controller 6 and the piano handle 4 by using magnetic force includes: an iron plate 44 attached to the case 40 of the wireless remote controller 6 , and an iron plate 44 at a portion corresponding to the iron plate 44 Permanent magnet 8 attached to piano handle 4. However, it is also possible to combine the wireless remote controller 6 and the piano handle 4 by using the magnetic force obtained by attaching a permanent magnet to the housing 40 of the wireless remote controller 6, and attaching a magnetic material to the part of the piano handle 4 corresponding to the permanent magnet. handle4. In this case, since the permanent magnet is attached to the housing 40 of the wireless remote control 6, the wireless remote control 6 can be attached to any object made of magnetic material, such as a metal table or a refrigerator, to make it more useful.

Furthermore, according to the present embodiment, since the wireless remote controller 6 is detachably supported on the front of the piano handle 4 serving as an operating handle, there is no need to provide an additional wall bracket or the like in which to place the wireless remote controller 6 . Therefore, consistency of design between the wireless remote controller 6 and the switch main body 1 can be achieved. In addition, the load L can be switched on/off by operating the piano handle 4 or the wireless remote controller 6, which makes it more convenient to use. In addition, the commercial AC power source AC and the load L can be connected to the switch main body 1 through two wires, and thus, the conversion to the conventional switch is easier.

The inventive feature according to this embodiment lies in the structure of the switch main body 1, and the other structures are the same as in Embodiment 4. Accordingly, the same reference numerals will be used for the same components, and descriptions thereof will be omitted.

Embodiment 4 is configured in which the push-down button 51 of the control switch SW1 mounted on the printed circuit board 7 is directly pressed by the pressing protrusion 39 on the back of the piano handle 4 . However, in this structure, the printed circuit board 7 in the main part of the switch main body 1 needs to be positioned close to the front surface of the cover 3 .

Therefore, in this embodiment, the partition portion 66 for transmitting the operating force of the piano handle 4 to the control switch SW1 is formed integrally with the cover 3, wherein the partition portion 66 is attached to the front surface of the switch main body 1 , and between the pressing protrusion 39 of the piano handle 4 and the push-down button 51 of the control switch SW1. The partition portion 66 having an approximately U-shaped groove on the front face of the cover 3 has a small width and can be freely bent forward/backward. A projection 66a standing forward protrudes from the front end (free end) of the partition portion 66 to come into contact with the push-down button 51 of the control switch SW1 on the back. That is to say, if the operating portion of the piano handle 4 is pressed, the operating handle 4 rotates around the axial portion 16, and the pressing protrusion 39 at the back of the piano handle 4 cooperates with the protrusion 66a provided at the front end of the partition portion 66 The surface of the contact is made, and furthermore, the partition portion 66 becomes bent, thereby pressing the push-down button 51 of the control switch SW1 by the protrusion 66a.

Furthermore, the present embodiment is constructed so that the operation force of the piano grip 4 is transmitted to the push-down button 51 of the control switch SW1 through the partition portion 66 formed integrally with the cover 3 . Therefore, by using the spacer portion 66 , the control switch SW1 can be arranged more freely in the main part of the switch main body 1 .

In the light receiving module 72a, as shown in FIGS. 24A and 24B, a light receiving element such as a photodiode is covered with a shield plate 72b made of metal in order to reduce the influence of external noise such as radiation noise. Also, a mesh-like guard member 72c is formed integrally with the guard plate 72b, and the light receiving surface (light receiving lens) of the light receiving device is covered with the guard member 72c. Furthermore, a cylindrical protruding wall 67 protrudes to surround the circular opening 22 on the front face of the cover 3, and surrounds the light receiving surface (see FIG. 23). With this configuration, the tolerance of the light receiving module 72a against static electricity discharged from the fingertip during its construction, and the electromagnetic shielding effect of the light receiving module 72a can be enhanced.

Embodiment 6 will be described with reference to FIGS. 25A , 25B and 26 . Its basic structure is basically the same as that of Embodiment 4. Therefore, regardless of whether the shapes are the same, the same parts will be given the same reference numerals, and descriptions and explanations thereof will be omitted.

The main body 2 forming the switch main body 1 is formed in a box shape with substantially equal length and width. Terminals 70A and 70B forming connection terminals Ta and Tb, and two printed circuit boards 7 are housed therein. These two terminals 70A and 70B have a conventionally known connection terminal structure, and include a terminal plate 71 and a cancel lever 73, the terminal plate 71 has a locking spring unified therewith, and the cancel lever 73 is used to cancel the terminal plate 71 and the lead wire Locked (closed) state between conductors in These two terminals 70A and 70B are respectively housed in two housing compartments 2d and 2e divided by a partition 2c which is rectangular in shape and whose left side is opened when viewed from above. Grooves 2f are formed on the side walls of the main body 2, and they communicate with the housing compartments 2d and 2e, respectively. Furthermore, the operating portion 73a of the cancel lever 73 is exposed to the outside of the main body 2 through the groove 2f. The cancel lever 73 is rotatably installed inside the main body 2, and can cancel the locked state between the terminal board 71 and the conductor in the lead by rotating along the groove 2f to expose the operating portion 73a outside the main body 2. Furthermore, each of the terminals 70A and 70B is electrically connected to a conductive pattern of the printed circuit board 7 via a conductive plate 74 . The control switch SW1 and the light receiving module 72 a etc. are mounted on the front one of the two printed circuit boards 7 , and the load switch unit 105 etc. are mounted on the rear one of the two printed circuit boards 7 . Reference numeral 75 in FIG. 26 denotes a heat dissipation plate coupled to the triac TRC of the load switching unit 105 .

The cover 3 is formed in a rectangular flat plate shape, which is larger in length and width than the main body 2 . By engaging the engaging protrusion 10 of the main body 2 with the engaging hole 12 of the engaging leg plate 11 protruding from the back of the cover 3, the cover 3 and the main body 2 are joined to each other to assemble the main parts of the switch main body 1. In addition, long openings 3a for box-shaped screws to be attached to the embedded box are formed at both ends of the central part of the cover 3, and the main parts of the switch main body 1 are directly attached to the embedded box without using the attachment frame 60. . Attachment openings 3 b for detachably attaching the decorative panel 90 are formed near the four corners of the cover 3 . Besides, as will be described, a pair of shaft supporting parts 3c protrude forward from both sides of the upper part of the cover, thereby pivotally supporting the piano handle 4, wherein each shaft supporting part 3c has a Shaft support opening.

The piano handle 4 is pivotally attached to the front face of the switch main body 1 so that the protrusion 25 and the engaging part 26 become the top and the bottom, respectively. Insertion holes 25 a for inserting a pair of shaft support portions 3 c protruding from the front face of the cover 3 are formed penetrating therethrough at both sides of the protrusion 25 . Axial portions (not shown) are formed on the inner surfaces of the insertion holes 25a respectively, which are axially supported to the shaft support openings of the shaft support portion 3c. That is, by inserting the shaft support portion 3c into the pair of insertion holes 25a, and then inserting the axial portion into the shaft support opening formed on the inner surface of the insertion hole 25a, so that they can be axially supported, A piano handle 4 can be pivotally attached to the front face of the lid 3 . In addition, approximately L-shaped support plates 4 b are located at both bottom ends of the piano handle 4 so as to support the wireless remote controller 6 attached to the engagement member 26 .

The wireless remote controller 6 basically has the same structure as that of the fourth embodiment. However, the wireless remote controller 6 according to the present embodiment is different from that in Embodiment 4 in that, in addition to the operable projecting portion 42a and the conductive portion 42b provided on the thin plate 42b, and including a pair of In addition to the on/off console 6A of the contact portions 50a and 50b, it also includes five kinds of timer consoles 6B to 6F shown in FIG. controller consoles 6B to 6F. Since the structures of the timer consoles 6B to 6F are the same as those of the on/off console 6A, descriptions and explanations thereof are omitted.

In addition, if an operation input is applied by pressing each of the consoles 6A to 6F, the control circuit unit 80 drives the light emitting diode LD2 by outputting a control signal to the transmission circuit unit 81, and further will correspond to each of the consoles 6A to 6F The instructions are transmitted in the form of wireless signals. For example, when the opening/closing console 6A is operated, a switching instruction for switching the on/off state of the load L is transmitted. Furthermore, when the timer consoles 6B to 6E are operated, timer instructions for terminating the load L after 1 minute, 10 minutes, 30 minutes, and 60 minutes, respectively, are transmitted. When the timer console 6F is operated, timer instructions for continuously operating the load L are transmitted.

The decorative board 90 made of synthetic resin has a rectangular shape. If the attachment protrusions (not shown) protruding from the four corners of its back are inserted into the attachment openings 3b of the cover 3 and engaged with them, the decorative plate 90 can be detachably attached to the front of the cover 3 to cover it. front. When the trim panel 90 is attached to the front face of the cover 3, the piano handle 4 is housed inside the trim panel 90, as depicted in Figure 25A.

If a switching instruction is received from the wireless remote controller 6, the control unit 103 of the switch main body 1 switches the operating state of the load L from ON to OFF, and vice versa, which is also performed in a similar manner in Embodiment 4. However, if a timer command is received from the wireless remote controller 6, timings (1 minute, 10 minutes, 30 minutes, and 60 minutes) on the timer start, which are included in the timer command. And when the timing on the timer ends, the operating state of the load L is switched from ON to OFF, thereby terminating the load L. Furthermore, if a timer instruction corresponding to the console 6E is received, the control unit 103 immediately switches the operation state of the load L from off to on without checking the time of the timer.

According to this embodiment, in the case that the load L is a lighting device, the lighting device can be automatically turned off after operating the timer consoles 6B to 6E for a certain period of time (timer time), so that the user can turn off the lighting device without turning it off. Fall asleep without the lighting. In this embodiment, the control unit 103 of the switch main body 1 performs a timer operation. However, the control circuit unit 80 of the wireless remote controller 6 is also capable of performing a timer operation, and furthermore, when the timer time elapses by operating the timer consoles 6B to 6E, a timer command can be transmitted as a wireless signal. The structure of the timer operation in this embodiment can also be applied to Embodiment 4, and further, timer consoles 6B to 6F can be placed in the wireless remote controller 6 in Embodiment 4, as shown in FIG. 27 .

Example 7

Embodiment 7 will be described with reference to FIGS. 28 and 29 . This embodiment is similar to Embodiments 4 to 6 in that it includes a switch main body 110 and a wireless remote controller 111 detachably attached to the front of the switch main body 110 .

The switch main body 110 includes a main part made of synthetic resin, and accommodates therein a circuit on a printed circuit board, wherein the circuit is the same as that of the switch main body 1 in Embodiment 4. A console 114 for pressing a push-down button of a control switch SW1 mounted on a printed circuit board is installed on the upper part of the front surface of the main part. A light transmission cover 113 covering the light receiving module 72a mounted on the printed circuit board is located at the lower part of the main part. In addition, a display window 115 is mounted to the console 114 for forwardly emitting the light of the light emitting diode LD1 mounted in the display unit 109 on the printed wiring. In addition, as in Embodiment 4, the main components were embedded in the wall surface by using an attachment frame. Attached to the front of the attachment frame is a conventionally known plate 112 comprising a flat plate frame 112a and a decorative plate 112b formed into a rectangular frame shape using synthetic resin.

Meanwhile, the wireless remote controller 111 has a flat rectangular parallelepiped-shaped casing. The case accommodates therein a circuit mounted on a printed circuit board which is the same as that used in the wireless remote controller 6 in Embodiment 4. As shown in FIG. This circuitry is housed inside the board 112 when the wireless remote control 111 is attached to the front of the switch body 110 . Furthermore, a transmissible lens 116 is provided at a portion facing the light transmission cover 113 of the switch main body 110 in the lower part of the housing, and conversely, a console 117 is provided at the upper part of the housing.

In addition, when the wireless remote controller 111 is detached from the switch main body 110, the load L can be turned on/off by pressing the console 114 of the switch main body 110 to turn on the control switch SW1. The load L can also be turned on/off by operating the console 117 of the wireless remote controller 111 to transmit a switching command as a wireless signal. Thus, there is no need for an additional wall bracket to store the wireless remote controller 111 , which enables design consistency between the wireless remote controller 111 and the switch main body 110 . Also, the user does not need to fix the wall bracket to the wall by using screws or adhesives. In addition, since the board used in this embodiment is not used for a single purpose, another wiring device can be combined, and furthermore, other operations can be easily added by changing the wireless remote controller.

In addition, the wireless remote controller 111 includes a light transmission portion 118 facing the light transmission cover 113 of the switch main body 110 . Therefore, even when the wireless remote controller 111 is attached to the front of the switch main body 110 as shown in FIG. 29, the load L can be controlled by receiving a wireless signal transmitted from another wireless remote controller. However, unless operation using another wireless remote controller is required, the light transmission section 18 can be omitted. In addition, since the light transmission part 118 is mounted on the console 117 of the wireless remote controller 111, even when the wireless remote controller 111 is attached to the front of the switch main body 110, the display unit 109 can be checked with the naked eye through the light transmission part 118. show.

The light emitting diode LD2 for transmitting wireless signals faces outside through the opening 119 formed at the upper wall of the housing of the wireless remote controller 111 . However, in case the transmissible lens 116 is mounted on the wireless remote controller 111 , another LED for transmitting wireless signals may be mounted so that it protrudes into the transmissible lens 116 . In addition, in the case that the transmittable lens is not mounted on the wireless remote controller 111 , then another light emitting diode for transmitting wireless signals may be mounted on a portion facing the light transmission cover 113 of the switch body 110 . In this case, even when the wireless remote controller 111 is attached to the front of the switch main body 110, the load L can be turned on/off by operating the console 117 of the wireless remote controller and by pressing the console 114 of the switch main body 110.

The protruding part 120 protrudes from the back of the wireless remote controller 111 so that when it moves to the front of the switch main body 110 in response to a pressing operation, it can press the console 114 on the front of the switch main body 110. A fixed axial portion 121 is protrudingly formed at the lower left portion of the housing of the wireless remote controller 111, which is inserted into the hole 112c of the plate 112 to be axially supported. In the upper left portion of the housing, a movable axial portion 123 is protrudingly formed, and is axially supported by being inserted into a hole (not shown) formed in the upper portion of the plate 112 . The movable axial portion 123 can be extended or contracted by operating a separation handle 122 provided on the front of the housing.

In addition, when the fixed axial portion 121 of the wireless remote controller 111 is inserted into the hole 112c of the plate 112, the movable axial portion 123 can be inserted into the upper hole of the plate 112 by operating the separation handle 122 to extend/contract the axial portion 123. middle. Therefore, the wireless remote controller 111 may be housed in the plate 112 provided on the front surface of the switch main body 110 as an operating handle. At this time, by positioning the fixed axial portion 121 and the movable axial portion 123 relative to the wireless remote controller 111, the rotatable angle of the wireless remote controller 111 is limited to a prescribed angle.

According to the present embodiment, the wireless remote controller 111 as a movable operating handle is detachably accommodated in the plate 112 provided on the front face of the switch main body 110, and includes a protruding portion 120 which when moved to the switch main body by a pressing operation 110 , the protruding portion 120 presses the console 114 of the switch body 110 . Thus, in the case where the wireless remote controller 111 is housed in the plate 112 provided on the front of the switch main body 110 , the wireless remote controller 111 can be used as an operating handle instead of the console 114 of the switch main body 110 . In addition, since the wireless remote controller 111 is mechanically operated, power consumption of the battery B of the wireless remote controller 111 can be saved compared to a structure in which an additional light emitting diode is installed to transmit a signal such as infrared rays.
