When the electric appliance is connected to the live wire and the zero wire at the same time, current can be formed, and the electric appliance can normally work. The figure shows a simple switch, light bulb circuit. When the switch is disconnected, the bulb is actually connected with only one line, no current exists, and the lamp cannot be turned on; when the switch is closed, current flows through the bulb and the lamp emits light.

Traditional mechanical wall switch box is exactly the break-make that utilizes spring and mechanical structure control live wire, advances one and goes out two lines and all be the live wire in fact, and this kind of connection is exactly "single live wire".

At present, the inside single live wire of mostly adopting of 86 boxes is walked, walks to single live wire, generally adopts the mode control of blinking to use electrical apparatus, promptly, through switch outage 3S about again the circular telegram control with electrical apparatus, the corresponding wave form of blinking is as shown in four.

In this application, the control switch may be a circuit switch that, when touched, causes only the circuit to flash momentarily and then resume. Specifically, the control switch performs one switching operation to cause two times of disconnection of the on-off state of the circuit: when the control switch is touched, the circuit is switched from a conducting state to a disconnecting state, so that the voltage drops or is cut off; when the touch is finished, namely the control switch is released, the circuit is switched to a conducting state, and the voltage is recovered, or an automatic timing rebounding structure can be arranged in the control switch, and the circuit is automatically recovered and switched to the conducting state after the circuit disconnection time reaches a preset fixed time length. Because the whole process time of the circuit disconnection and the circuit conduction is short, the control switch can enable the circuit to generate one-time flash after being touched and pressed every time.

Utilize the flash control to use electrical apparatus can let with electrical apparatus and keep on-line state, do not fall off because of turning off the light, but this kind of mode has the drawback: in some cases, the peripheral switch is triggered, the electrical appliance cannot sense the external switch, and the user needs to press the peripheral switch again.

When the electric appliance is controlled by the control switch, the control switch is matched with the peripheral switch to realize the flash control of the electric appliance when the peripheral switch rebounds. Fig. 2-3 are schematic diagrams of states of the electrical appliances under different pulses, i.e., a first state and a second state.

As shown in fig. 2, when the electrical appliance is in an on state, the external switch is triggered within a time period T1, T1 is greater than or equal to 0.5 ″, and is less than or equal to 3 ″, and a flash-off occurs, the electrical appliance detects a pulse signal, and then a light-off instruction is executed; the electric appliance is in a light-off state, the external switch is triggered within a time period of T2, T2 is more than or equal to 0.5 'and less than or equal to 3', and the electric appliance detects a pulse signal and executes a light-on instruction at the moment; when the electrical appliance is in an on state, the external switch is pressed for a long time within a time period of T3, T3 is more than or equal to 5', the electrical appliance does not detect a pulse signal for a long time, the state is considered to be a power-off mode, the external switch is released at the moment, and the electrical appliance is in an on state in a default state.

Because different electrical appliances execute the light-on or light-off command and need to receive the pulse reaching the corresponding width, when the external switch is pressed too fast, as shown in fig. 3, T2<0.5 ", the generated pulse is too narrow, so that the electrical appliances which cannot sense the pulse less than 0.5S cannot detect the action, and the light-on or light-off command is not executed.

The condition that the instruction became invalid appears turning on the light or turning off the light, if for single with electrical apparatus, can repetitive motion in order to realize corresponding the instruction, however, because there is the difference in every lamp material or internal circuit structure, the required Tx time of response also can have the difference, when a plurality of electrical apparatus, especially a plurality of ball bubble, down lamp are parallelly connected, because the different trigger command with electrical apparatus has certain width, when the action of pressing peripheral hardware switch was too fast, the lamp that will appear does not sense the peripheral hardware switch and presses, and the partial lamp that appears is bright, the condition that partial lamp goes out.

The applicant has found that the reason for the above problem is that the pulse width generated is related to the time for pressing the peripheral switch, and the duration of the pressing time is such that Tx is different each time, and when Tx is less than 0.5S, the electrical appliance may not sense and the user is required to press the key again. Therefore, in the embodiment of the application, the relationship between the pulse width and the time for pressing the peripheral switch is considered to be separated, and the control switch can generate a pulse with a fixed pulse width no matter the time length for pressing the peripheral switch is realized through a certain technical means, so that the problem of failure of the flash command is solved.

The electrical appliances in the invention can be electrical appliances such as lighting lamps, air conditioners, fans, electric heaters, televisions, sensors and the like, and the embodiment of the application takes the lighting lamps as an example for explanation.
