In other embodiments, as long as the circuit, device or device can control the power supply state of the socket through the control signal, it is within the protection scope of the present invention.

Relay 122 selects JQX-38 high-power relay, and relay 122 is a normally open type. When the judging device sends a control signal, that is, the proximity switch sends a control signal, the coil of relay 122 is energized, and the normally open contact of relay 122 is closed, that is, the live wire and the socket 130 is turned on, so as to realize the operation of supplying power to the socket.

The drive circuit 121 is for example but not limited to an integrated operational amplifier, the specific model may be LM358, which is used to amplify the control signal sent by the proximity switch to improve its drive capability, so that the normally open contact is triggered to close after the coil is energized.

It works as follows:

When the plug 140 is close to the proximity switch 111, the proximity switch 111 sends a control signal to the driving circuit 121 to amplify the control signal to drive the relay 122 to work, so that the live wire and the socket 130 are conducted, and then the power supply operation to the socket is realized.

third embodiment
