4 way switch wiring

Before you can install a four way you need to understand how a three way circuit works so please see my how to install a three way switch before attempting a four way. Also please keep in mind that I only show one way to install a 3 way switch. There are few ways to wire a 3 way.

 

In order to have a four your need to have a three way. No matter how many switch’s you want in your circuit you will only have two three way switch’s. You’ll have one at the beginning and at the end. All switch’s in between will be a 4 way switch. Even if you intend to have only three switch’s or ten of them.

 

So lets say you have a existing three way circuit and you want to add another switch to it. All you have to do is find the (3-wire) running from one 3-way switch to the other 3-way switch and install the 4-way switch in between the two. Now that’s sounds easy but you will most likely find that wire way to short to just cut it and install it in a new switch box.

So in short, you would cut the wire in between the two 3 ways and install a 4 way switch. This is meant as a guide. Your wiring could be very different.

No matter what you can never ever use a ground wire for anything else but a ground.
