How to connect L, L 1, L2, neutral wire and live wire behind a single control switch?

The picture shows the physical wiring diagram of the dual-control switch and incandescent light bulb, which is clear at a glance.

See the picture above, which is the physical diagram of the connection of the 86-type double-control switch. 220V AC current flows through live wire, left double-control switch L, right double-control switch L 1 or L2, right double-control switch L 1 or L2, L line, one end of incandescent light bulb, the other end of incandescent light bulb, and the zero line of 220V power supply line. In this case, no matter what the double control switch is.

The expansion data panel switch is generally composed of a bottom box and a panel. The main part of the bottom box is the panel part, and the bottom box mainly plays the role of fixing and supporting the panel. With the deepening of people's understanding of electricity and the increasing attention to the safety of electricity use, most of the switches mentioned refer to single-control switches. As the name implies, a single control switch means that a single or multiple electrical devices are controlled by a switch, and there is a one-to-one or one-to-many relationship with the electrical devices.

The common switches are mainly household switches, usually with open and concealed devices. According to their specifications, there are 86 models, 1 18 models, 120 models and so on. According to the number of switch buttons in the same panel, it can be divided into single-open, double-open, triple-open and quadruple-open types. Household switches are usually made of engineering plastics by encapsulating metal conductive strips and wiring contacts.
