How to solve the wiring problem of three-charge control switch

The wiring diagram of the charging control switch is as follows:

The incoming line is short-circuited at L 1, L2 and L3, and the outgoing line is also the live line! L 1 1, L2 1, L3 1 respectively. There should be no neutral wires in the switch, and these wires should be live wires (or control wires). As long as there is one power cord on the whole switch panel, you can give it up when you meet two power cords-wrap it with insulating tape.

Extended data

Single-control switch is the most common in home circuits, that is, one switch controls one or more appliances. According to the number of connected electrical appliances, it can be divided into single-control single-connection, single-control double-connection, single-control triple, single-control quadruple and other forms. For example, the kitchen uses a single control switch, and one switch controls a group of lighting lamps. There may be three spotlights installed in the living room, so it can be controlled by a single control triple switch.

A single control switch has two terminals, which are connected to the incoming line and the outgoing line respectively. When the switch is on/off, there are two States: on or off, which makes the circuit a path or an open circuit.
