Dual control switches are very common in daily life, but do you understand the dual control switch circuit diagram? Do you know how to connect the dual control switch? If you understand the dual control switch circuit diagram and the dual control switch wiring diagram, it is more convenient to solve some simple dual control switch line problems in life.
The dual control switch is a switch that performs two kinds of control on the device. It refers to the separate control of two places in a certain device. For example, if it is a light, enter the living room to open the living room lighting, and then go to the living room when the bedroom is going to sleep. Turning off the lights is very cumbersome, and it is very convenient to install a switch in the bedroom to control the living room lights. The realization of this function depends on the dual-control switch circuit diagram. How to connect the dual-control switch?
The double control switch wiring diagram is divided into a single double control switch wiring diagram and a double dual control switch wiring diagram. The single double control switch principle is that two single pole double throw switches are connected in series and then connected to the circuit, and the three terminals are respectively connected. Connected to two contacts and one knife, the double connection method connects the two contacts of the two single-pole double-throw switches respectively, and the two switches have the two ends of the switch connected to the two ends of the electric lamp.
The principle of the double-control dual-control switch wiring diagram is to control two electric equipment through the switch of two buttons. How to connect the double-control double-control switch, first connect the intermediate terminal of one dual-control switch to the live line, and the other double control The middle terminal of the switch is connected to the lamp cap. The dual control switch circuit diagram is the core device of the whole dual control switch. It realizes dual control by two loops, one switch at a time, and realizes the function by single pole double throw control.
