After the controlled device 20 is woken up, the controlled device 20 provides a supply voltage to the control unit 300, and the control unit 300 receives the supply voltage and outputs a driving signal, such as a high level signal, to the control terminal CTR of the driving unit 400.

When the KEY K1 is pressed, VCC is grounded after passing through the resistor R1, the diode D1, and the KEY K1 in sequence, so as to form a discharge loop, because a voltage drop exists in the diode under the conduction condition, the voltage output by the output terminal KEY of the KEY detection unit 500 is the second voltage divided by the diode D1, and the voltage value of the second voltage is determined according to the voltage value of VCC, the resistance value of the resistor R1, and the voltage drop of the diode D1.

When the controlled device 20 does not supply a voltage to the control unit 300, as shown in fig. 4, the control unit 300 does not output a driving signal to the driving unit, that is, the control terminal CTR of the driving unit 400 receives a low level, the first switching tube Q1 is turned off, so that the relay RY1 stops operating, and the first contact 21 and the second contact 22 of the relay RY1 return to a normally closed connection.
