Zero power consumption touch switch module circuit

Abstract

The present invention discloses a zero power consumption touch switch module circuit which is applied to an electronic product. A button switch and a touch switch are used to turn on and turn off a switch of an electrical appliance. In a state that the electrical appliance is turned off, zero power consumption standby of the electrical appliance is achieved. A fifth pin is connected to a +5V power supply of the electrical appliance, and a sixth pin is connected to a CPU control startup and shutdown signal controlling terminal, wherein the low level is used as a startup signal. A third pin and a fourth pin of an optical coupler IC2 are connected to startup and shutdown controlling terminals of the controlled electrical appliance. A first pin is connected to a power supply input end of a 220V power supply, and a seventh pin is connected to one end of a 220V power input of the controlled electrical appliance. After the 220V power supply is connected, the 220V voltage at the L end of the first pin is divided into two paths. One path of the voltage supplies power to a first pin of a bidirectional triode thyristor VT1. The other path of the voltage is connected to a bridge rectifier diode a via a capacitor C1, and the voltage is stepped down by the capacitor C1, rectified by the bridge rectifier diode a, stabilized by a voltage-regulator diode VD1 and filtered by a capacitor C2, and then a 9V voltage is output for powering interior luminescent tubes of an optical coupler IC1 and the optical coupler IC2.
