Abstract
A wireless switching circuit includes a charging capacitor, a voltage converter, an infrared sensor unit, a single chip microcomputer (SCM), a zero trigger circuit, and a thyristor. The charging capacitor is used to store and supply power. The voltage converter is used to convert alternating current (AC) voltage into direct current (DC) voltage to charge the charging capacitor. The infrared sensor unit is used to output control signals according to sensed infrared signals. The SCM outputs a trigger signal according to the control signals from the infrared sensor unit. Input ends of the zero trigger circuit are connected to the SCM to receive the trigger signal. An anode and a cathode of the thyristor is connected to a power supply line for the socket. A control end of the thyristor is connected to an output end of the zero trigger circuit.
