This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches coming after. It has 4 terminals or poles and consists of two 3 way switches that are modified.
How To Wire Switches
4 way light switch circuit diagram. For a discussion of how to wire such circuits see 3 way and 4 way light switches. If more than three switches are needed simply place more 4 way switches between the three way switches. First of all we need to go over a little basic terminology on switches. Do you need a 3 way switch wiring diagram. This allows you to control a load from other locations in addition to the 2 locations that a 3 way circuit provides. As you will see most 4 way switch wiring is placed between the wiring of two 3 way switches therefore a 4way switch is installed with two 3way.

This circuit is wired the same way as the 3 way lights at this link. The center switch is 4 way switch while the outer two switches are 3 way.
4 way switch wiring with light first. 4 way switch configurations are used to control lights with three or more switchesa 3 way switch is used on each end with one or more 4 way switches in between the two 3 way switchesthey do not have an onoff position like single pole switches.
