What Is A 2 Way Light Switch

A two way light switch can also be used as a one way light switch that is a switch that turns a light or lights on and off from one switch without any other switches being attached to that light circuit.

What is a 2 way light switch. How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. Before jumping straight into the feature specific table let s go through some useful information. The 2 way switch or single pole double throw switch is a three terminal switch. There are two methods of making 2 way switching connection one is 2 wire control and another is 3 wire control.

The other terminal is marked as l1 and is the output to the light fixture. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used. In a hallway or large room for example installing three way switches at both ends lets you turn the light fixture on or off from both locations. A three way wall switch is a common type of light switch that makes it possible to control a ceiling light or other electrical fixture from two different locations in a room.

A two way light switch is a switch that can be used in conjunction with another two way light switch to turn a light or lights on and off from more than one location. When wiring a 2 way switch circuit all you re really doing is controlling the power flow switching off on to the load a light lamp outlet ceiling fan etc now a typical circuit will contain a 3 wire cable known as romex. Two way switch can be operated from any of the switch independently means whatever be the position of other switch on off you can control the light with other switch.

Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used. The common is for the live wire that supplies the input voltage to the switch. This arrangement is often found in stairways with one switch upstairs and one switch downstairs or in long hallways with a switch at either end. A one way light switch has two terminals which is a common marked as com or c.
