How to draw the connection of Eden one-control switch?

An equal control, very simple, but also very common. Just connect the power supply, switch and light in series. Lights connected in this way can only be controlled by switches.

Yi Deng multi-control principle and circuit diagram

Methods/steps

1. To understand the principle of Yideng multi-control, we must first know the series and parallel connection. First, series connection is introduced. Series connection is very simple, just one line, all electrical appliances are connected in series, which is called series connection. The characteristic of series connection is that each electrical appliance shares the voltage of power supply according to the size of resistance, and the greater the resistance, the greater the shared voltage.

2. Parallel connection, two lines or multiple lines, is also very simple. The characteristic of parallel connection is that all electrical appliances share the current equally according to the resistance. The smaller the resistance, the greater the shunt current.

3. Series-parallel connection means series-parallel connection, and there are both series and parallel connections in a circuit. Analyze carefully and don't make mistakes.

4. One control is simple and common. Just connect the power supply, switch and light in series. Lights connected in this way can only be controlled by switches.

5. Yi Deng two controls, more common in corridor lights. A switch downstairs and a switch upstairs can control this light. Unlike ordinary switches, switches are single-pole double-throw switches.

6. Easy light and three controls, mostly used in families. All three switches can control one lamp, where S 1 and S3 are single-pole two-position switches, and S2 is double-pole two-position switch. In this way, each switch can be controlled independently.

7. First-class four controls and first-class five controls and six controls, or even more.
