Question or Comment?
A reader of this site had a question about wiring 3-way light switches. Each 3-way switch box would contain a single pole switch each controlling a light.
Diagrams shown on this page are simplified for clarity. Electrical outlet boxes can have numerous NM cables going in and out. See “Actual Switch Box Wiring Diagram” below.
Ground connection diagram is shown separately.
