What is the principle of dual control switch dual control switch
Although we often hear and use dual-control switches in our daily lives, many consumers still do not know what dual-control switches and dual-control switches do . Today, with the small series to see what is the principle of dual control switch and dual control switch , for your reference oh.

Dual-control switch is a switch with two contacts at the same time with normally open, normally closed, usually with two dual control switch to control a light or other electrical appliances, means that there can be two switches to control the switch of lamps and other electrical appliances, for example, in the next When the building opens the switch, turn off the switch after going upstairs.

The so-called dual-control switch principle is achieved by a combination of two independent single-pole, double-throw switches. Almost every brand and series switch on the market today has unipolar and bipolar switches, no matter which switch you switch (K1 or K2) The state of the entire circuit will be switched (connected and disconnected). This enables any switch to turn on or off the controlled lamp at any time. This is the dual control. Similarly, a three-control switch means that three different locations of switches can optionally use one of them to freely control one lamp. Its circuit is complicated and a double-knife double switch is used.
