Wireless switching circuit

A wireless switching circuit, comprising:

• a charging capacitor;
• a voltage converter to connect a socket;
• a switch connecting the voltage converter to an alternating current (AC) power;
• wherein the voltage converter converts AC voltage from the AC power into direct current (DC) voltage to charge the charging capacitor when the switch is turned on;
• an infrared sensor unit to output a power signal or a standby signal according to infrared signals sensed by the infrared sensor unit;
• a single chip microcomputer(SCM) connected to the infrared sensor unit, wherein the SCM outputs a trigger signal when receiving the power signal from the infrared sensor and stops outputting the trigger signal when receiving the standby signal from the infrared sensor;
• a zero trigger circuit, wherein input ends of the zero trigger circuit are connected to the SCM to receive the trigger signal;
• a thyristor, wherein an anode of the thyristor is connected to a zero line of the AC power, a cathode of the thyristor is connected to the anode of the thyristor through the switch;
• a control end of the thyristor is connected to an output end of the zero trigger circuit;
• when the zero trigger circuit receives the trigger signal from the SCM, the thyristor is turned on, and the AC power is connected to the socket;
• when the zero trigger circuit does not receive the trigger signal from the SCM, the thyristor is turned off, and the AC power is disconnected from the socket.
