By the end of this article, you'll have a clear understanding of how to wire a 2 gang 3 way switch, ensuring your space is both functional and safe.
What is a 2 Gang 3 Way Switch?
A 2 gang 3 way switch allows you to control two lights or sets of lights from three different locations. This is particularly useful in long hallways, staircases, or large living spaces. The 'gang' refers to the number of switches in one box, and the 'way' refers to the number of locations from which you can control the lights.
