This page describes the most common wiring methods for 4-way switches. Use these diagrams to identify the method that was used to wire your circuit.

As always, if you’re not comfortable working with electricity, please contact a licensed electrician in your area. Working with electricity is dangerous – if you don’t understand it, call someone that does.
