What is a dual control switch? How to connect the two-control switch?

First, what is the dual control switch

Simply put, the difference between a single-control switch and a dual-control switch is very obvious. A dual-control switch is one or two switches that control one power supply. For example, when you enter the living room, you turn on the living room light at the entrance of the living room. You run to the bedroom and want to rest. At this time, it is very troublesome to go to the living room to turn off the living room lamp. If you install a dual control switch in the bedroom, You don't have to go to the living room to turn off the lights, which saves time and effort. So dual control refers to two locations in different places, which can control one power supply at the same time.

Second, single dual control switch wiring method

The single dual-control switch is simply a two-pole, double-throw switch connected in series and then connected to the circuit. Each single pole double throw switch has three terminals that connect two contacts and one knife. After knowing this information, it is not difficult to know how to connect the single dual-control switch.

Connect the two contacts of the two single-pole double-throw switches, and then the two switches are connected to the two ends of the lamp as the two ends of the entire switch. Thus, when the switches 1 and 2 are simultaneously connected to the respective contacts 1 or simultaneously to the contacts 2, the circuit is turned on, and the lights are on, so both switches can control the lamps. Two switches can be placed at the door and bedside of the bedroom, or at the ends of the hallway, to illuminate, save time and effort.

Third, double dual control switch wiring method

The dual dual-control switch is a two-button switch. Simply put, it means that two light sources are controlled by two buttons on one panel, that is, two switches control the two circuits. First connect the middle terminal of a dual control switch to the live wire, then connect the middle terminal of the other dual control switch to the lamp head, and then connect the return line, that is, connect the upper and lower terminals with two green wires; The wire is connected directly to the other contact of the lamp head so that the connection is completed.
