Here’s what to know. This guide explains the type of work and why it can be needed. It is not a remote diagnosis or a do-it-yourself wiring tutorial.
What does this involve?
Wiring complex lighting circuits with three or more control switch locations.
How does it work?
Four-way switching can add another control point between two three-way switches. The routing must be planned so each location works as expected.
What affects the job?
Adding a third switch may require new cable through finished walls. Send us the locations you want to control the light from.
What should you tell us?
A picture of the existing outlet or switch, the room where it is located, and whether the problem is new or ongoing. You do not need to know the electrical terms. Tell us what you see and what you want to change.
Keep safety in mind
The U.S. Consumer Product Safety Commission’s home electrical checklist explains common warning signs. For generator-related jobs, see the Electrical Safety Foundation International’s generator guidance. Any code or permit decision needs to be checked for the actual property.
Is this what you need help with?
Tell us a little about your project and where you're located. We'll confirm whether it's a job we can take on and explain the next step.
