Description

switch

technical field

The utility model relates to a switch, in particular to a switch capable of enabling users to clearly know whether the power supply is turned on and which switch is in use.

Background technique

In the evolution and progress of the times, humans have developed many tools and equipment that are convenient and beneficial to the people. When using these tools and equipment in the early days, they needed to be driven by manpower. However, as humans developed various We began to know how to use these energy sources to replace manpower as power, such as: water power, fire power, electric energy, solar energy, etc., which brought great convenience to people's life.

As far as electric energy is concerned, in today’s society, power can be easily obtained almost everywhere, and because of its convenience, most of the various appliances in daily life are driven by electricity, and these electrical appliances are all The power switch is used to control its opening or closing; as for the design of the power switch, it is often seen that the industry has provided a power indicator to let the user know clearly whether the power of the switch is indeed turned on when the power switch is turned on. Lights, or night lights are provided to allow users to clearly know the position of the power switch in dark places and at night.

Among them, as shown in Figure 4 and Figure 5, it is a common switch with a power indicator light. The upper end of a housing 31 of the switch 3 is pivotally provided with a pressing part 32 that can be pressed movable to both sides respectively. The power indicator light 33 can be accommodated, and the first, second, and third terminals 34, 35, and 36 are respectively provided at the lower end of the housing 31. The pin 331 is in contact with the second terminal 35, and the second terminal 35 is in contact with the second pin 332 of the power indicator light 33 through the load 38 through the metal elastic body 37. In addition, the second terminal 35 can be provided with the conductive sheet 351 and the third The pin 36 is in contact with conduction; in this way, under normal conditions, since the first pin 331 of the power indicator 33 is not in contact with the metal guide 341 of the first terminal 34, the power indicator 33 will not emit light. (as shown in FIG. 4 ), when the pressing part 32 is pressed to make its first pin 331 connected to the metal guide 341 of the first terminal 34 (as shown in FIG. 5 ), the power indicator light 33 will light up. , for the user to know that the power is indeed turned on.

However, although the above-mentioned power indicator lights and night indicator lights can respectively achieve their predetermined expected effects, it has been found in actual implementation and use that, looking at the various switch products on the market, none of them have both advantages. There are many switches, so that various switches still have incomplete functions in use. Either there is a problem of not being able to clearly know whether the switch is normally turned on or not, or there is the inconvenience of not being able to clearly know the position of the switch at night or in a dark place. question.

Contents of the invention

The purpose of the utility model is to provide a switch, which can not only let the user clearly know whether the power supply is turned on, but also can display which switch is in use.

The purpose of this utility model is achieved in this way: a switch is composed of a switch body and an indicator light device assembled on the switch body, and the upper end of a housing of the switch body is pivotally provided with pressing parts that can be pressed to both sides respectively. The lower end of the housing is respectively provided with first, second, third, and fourth terminals. The first terminal can use a movable pivoted conductive piece to contact and conduct with the second terminal to output power to the outside. The conductive piece of the first terminal is just received A metal elastic piece is in contact with each other, and the third and fourth terminals are respectively equipped with elastic conductive pieces; the indicator light device is respectively equipped with a night indicator light and a power indicator light, and the night indicator light and the power indicator light are respectively equipped with protective loads to indicate The light device can be assembled and inserted into the pressing part of the switch. The other end of the metal elastic part of the switch is against the common pin of the night indicator light and the power indicator light. The elastic conductive parts of the third and fourth terminals of the switch correspond to The load connected to the other pin of the night indicator light and the power indicator light.

The switch and the indicator light device can be arranged on the circuit board.

The utility model has the advantages that: it can be known from the composition and operation description of the above-mentioned components that the utility model is compared with the conventional one, because the utility model is provided with a night indicator light and a power supply indicator light in the switch at the same time, so that Not only can the light emitted by the night indicator light at night or in a dark place let the user know the position of the switch clearly, but also can let the user know the position of the switch by the light emitted by the power indicator light when the switch is turned on. Clearly know whether the power is on and which switches are in use.

Detailed ways

First, please refer to Fig. 1 to Fig. 3, the utility model is composed of a switch body 1 and an indicator light device 2; wherein:

The switch body 1 is pivotally provided with a pressing portion 12 on the upper end of a housing 11 that can be pressed to both sides respectively, and the first, second, third and fourth terminals 13, 14, 15, 16 are respectively provided at the lower end of the housing 11. The first terminal 13 can use a movable and pivoted conductive piece 131 to contact the second terminal 14 for external output power, and the conductive piece 131 of the first terminal 13 is just in contact with the metal elastic member 17, while the third The four terminals 15 and 16 are respectively provided with elastic conductive members 151 and 161 .

Indicator light device 2 is respectively provided with night indicator light 22 and power supply indicator light 23 on circuit board 21, and night indicator light 22 and power supply indicator light 23 are all respectively provided with protective load 221,231, and indicator light device 2 just can supply The assembly is inserted into the pressing part 12 of the switch body 1, so that the other end of the metal elastic member 17 of the switch body 1 is pushed against the common pin of the night indicator light 22 and the power indicator light 23, and the third and fourth ends of the switch body 1 The elastic conductive members 151 , 161 of the terminals 15 , 16 can respectively correspond to the loads 221 , 231 connected to the other pins of the night indicator light 22 and the power indicator light 23 .

In this way, when the switch body 1 is in the closed state, since the elastic conductive member 151 of the third terminal 15 corresponds to the load 221 against the night indicator light 22, and the metal elastic member 17 is connected to the first terminal 13 through the conductive sheet 131 A loop is formed to make the indicator light 22 at night show a conduction and light-emitting indication effect, and because the elastic conductive member 161 of the fourth terminal 16 does not make any contact with the load 231 of the power indicator light 23, the power indicator light 23 It will not emit light; when the switch 1 is pressed and opened by the pressing part 12, since the elastic conductive member 161 of the fourth terminal 16 and the load of the power indicator light 23 are in a contact conduction state, at this time, if the power supply is correctly conducted No mistake, then the power indicator light 23 will send light immediately.

It can be seen from the composition and operation description of the above-mentioned components that the utility model is compared with the conventional switch, because the utility model is provided with a night indicator light 22 and a power indicator light 23 in the switch body 1, so that it can not only At night or in a dark place, the light emitted by the night indicator light 22 allows the user to clearly know the position of the switch, and when the switch is turned on, the light emitted by the power indicator light 23 can also make the user Clearly know whether the power is on and which switches are in use.
