Can the double control switch be used as a double single control switch? How to connect the wires? material object

Double double control switch can be used as double single control switch. There are two methods:

The first method is the simplest, using only a set of single contacts of a switch as a single control switch.

The second method is to play the dual-control function through wiring, so that one of the dual-control switches can move at will to realize the on-off of the controlled electrical appliance.

As shown above: If the first method is used, there are four switches for double-beam dual control, and the two wires only need to be connected as AB, BC, DE, EF? Four groups, any group can realize the on-off control of electrical appliances.

This method is the simplest, but only one switch works and has a fixed direction, and one switch is idle. In the second method, two switch wires can BE connected, and then AD is connected with short wires, and CF is also connected with short wires, so that any switch can control the electrical appliance, regardless of the direction.

Method 1: Corresponding to the following figure, AB, BC, DE, EF, any group can be connected with control lights.

Method 2: Corresponding to the following figure: Choose BE access and connect AD and CF with short lines.

The double control switch is used as a single control switch, and L 1 or L2 can be connected to an electrical appliance (load).

Wiring diagram of double-control switch as single-control switch

Extended content: Single-connected double-control switch is actually a switch which is connected to the circuit after two single-pole double-throw switches are connected in series. Each single pole double throw has three terminals, which are respectively connected with two contacts SPDT a knife.

Double-control switch is actually two single-pole double-throw switches connected in series and connected to the circuit. Each single pole double throw has three terminals, which are respectively connected with two contacts SPDT a knife.

Specific connection: connect two contacts of two single-pole double-throw switches respectively, that is, contact 1 of switch 1 is connected with contact 1 of switch 2, and contact 2 of switch 1 is connected with contact 2 of switch 2, and then the knives of the two switches are connected to the two ends of the lamp as the two ends of the whole switch.

In this way, when the blades of switches 1 and 2 touch their respective contacts 1 or contact 2 at the same time, the circuit is connected and the lights are on. If one knife of two switches touches contact 1 and the other touches contact 2, the circuit is blocked and the light goes out. So both switches can control the lights.

These two switches can be placed at the upper and lower ends of the stairs or at both ends of the corridor, so that the lights can be turned on before entering the corridor and turned off at the other end after crossing the corridor, which can not only illuminate, but also prevent people from wasting electricity when the lights are on.

"Lian" means that there are several switch buttons on the same switch panel.

"Control" refers to the control mode of the switch button, which is generally divided into "single control" and "double control".

"Single control" means that a button controls a group of light sources.

"Double single control" means that there are two buttons on a switch panel to control two groups of lights respectively. For example, the control of corridor lights with stairs on both sides.
