What is the connection method of pull-in switch and push-button switch, and how to connect it? Now let's give you a detailed introduction. Please know more about it.
Otherwise, I dare not say that the single-control connection of the electric lamp, I dare to clap my chest, is absolutely the most widely used connection in the world. The electric lamp circuit is the first step for the electrician to understand all the circuits, and the single-control connection method of the electric lamp is the first step of the electric lamp circuit.
Single Control Connection Method and Principle of Electric Lamp
Light single-control switch, no matter which one, can be regarded as a single-pole single-throw switch. In the circuit diagram, the marks are as follows
All single-control switches, regardless of their form, have only two terminals (double-control, multi-control switches do not count as single-control). Some switch terminals are marked with L (some brands are marked with COM) and L1.
When connecting, L connects to the line and L 1 connects to the line. At this time, special attention should be paid to the fact that the incoming line must be a line of fire.
Wire-pulling switch
Want to use this kind of switch in every household, now this kind of switch has been gradually eliminated, even if you want to buy a switch, you have to find several hardware stores.
When wiring, two wiring posts, one wiring and one lamp are enough.
Key switch
Single Open Single Control Switch
This switch is currently the most commonly used, almost every family in the decoration to buy at least a few, its terminal in the back.
The same two terminals, but the switch's terminals are marked. The iconic brands are labeled L and L1, and some other brands are labeled COM and L1. The wiring method is as follows
Multi-open single-control switch
In addition, there are several buttons on the panel, each button can control a light.
Although the appearance is the same, but the back of the terminal is different. Take Sankai as an example. Some brands have six wiring posts on the back, that is, two wiring posts correspond to each button.
Such a switch, although not very neatly arranged, but also very good connection. There are letters A, B and C in the terminal label, which correspond to three front buttons from right to left. The wiring can be regarded as a single open single-control switch wiring for each two wiring posts.
There's another kind of terminal, like this.
It's also three-way single-control, but only four terminals. Careful observation will reveal that there is only one common point (L or COM is called common point) in the identification of the terminal, that is, the incoming end. This switch only needs to be connected to an incoming line, while L1, L2 and L3 correspond to panel keys from right to left, respectively. The wiring method is as follows
