How to wire the intelligent switch signal line in the hotel?

Now the wiring of intelligent switch is very simple. Specifically, it is like this: live wire, zero wire and signal wire (two cores). The switch base is divided into strong current interface and weak current interface. The high-voltage interface is connected with live wire and zero wire, and the weak-current interface is connected with signal wire. Each switch in the high-voltage part only needs to be connected to the line in the room: each switch in the low-voltage part can be connected in series (the two cores of the signal line cannot be connected in reverse). Intelligent switch itself is weak current control, and now most of them are touch screen panels. It is very convenient to use, and the installation is not complicated. Intelligent switch is becoming popular and is a very good choice. .
