What is a 4 way light switch?
A four-way switch is similar to a three-way, except it has four terminals (plus a ground terminal) and controls one fixture from three locations. This type of switch must be combined between two three-way switches to form a circuit. While more uncommon, this is a good option for large rooms with several entrances.
Can you wire a 4 way switch as a single pole?

How do you add a 4 way switch to a 3 way circuit?
All you need to do is find the 4 wire that currently runs from one of your 3 way switches to the other. You will need to cut/break this and add the 4 way switch in between. The 4 way switch will have 2 terminals marked IN and 2 marked OUT.
