Double-on and double-control switches are actually two groups of single-on and double-control switches combined together. Each group independently dual-controls one light without affecting each other.

2. This is a single-connected dual-control panel with a three-hole socket. The socket part: L is connected to the live wire, N is connected to the neutral wire, and PE is connected to the ground wire; the switch part: L is connected to the live wire of the power supply, and L1 is connected to the lamp. , L2 is left empty (here it is used according to the single control switch); if possible, it is best to power the socket and lamps separately, so that they do not affect each other and improve the reliability of the power supply.

The picture below is drawn with a power supply.
