Ex-Cs Series 2 Way Wall Switch - 2g2w-Cs2722

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.

If we are going to turn a light on and off from 2 different locations, we need 2 Single Pole Double Throw or SPDT switches. A SPDT is called a 2-way switch in the European Union, and a 3-way switch in North America. A SPDT switch has 3 terminals. It will have one terminal in and 2 terminals out.

Is a 2 way switch different than a regular switch?

The single switch controls a single light (or lighting circuit). 2 Way Switches: A '2 way' switch means there is another switch controlling the same light. These are often used on a stair case, large room with switches by each door.
