Understanding Four Way Switch Wiring
Wiring 4-way switches
- Tim, 4-way switches work with 3-way switches. When more than two switches will be used to control lighting 4-way switches must be installed between the 3-way switches.
- There are several ways to wire 3-way and 4-way switches, and typically the cable leading to the light fixture is installed to the switch box that has the power supply cable because of the required neutral for the light fixture.
- The resources below provide links to wiring diagrams that will assist you to wire 4-way switches.
