A 3 way selector switch is used to control the flow of electricity in a circuit. It is commonly used in household wiring, where you can control a light or a set of lights from two different locations. In this article, we will discuss the wiring diagram for a 3 way selector switch in detail.
What is a 3 Way Selector Switch?
A 3 way selector switch is a type of switch that is used to control a light or set of lights from two different locations. It has three terminals, which are common, traveler, and traveler. The common terminal is the center terminal of the switch and is connected to the power source. The traveler terminals are connected to the light or set of lights, and they are used to control the flow of electricity between the two locations.
The 3 way selector switch is also known as a “multiway switch” or a “three-way switch”. It is commonly used in household wiring, especially in stairways, hallways, and large rooms where you need to control a light or set of lights from two different locations.
Wiring Diagram for a 3 Way Selector Switch
The wiring diagram for a 3 way selector switch is shown below:
| Terminal | Function |
|---|---|
| Common | Connected to power source |
| Traveler | Connected to light(s) |
| Traveler | Connected to light(s) |
In this diagram, the common terminal is connected to the power source, while the traveler terminals are connected to the light or set of lights.
