3-Way Switch Wiring Diagram: How to Connect Two Switches to One Light #1438774 (License: Personal Use)

This schematic illustrates a classic 3-way switch configuration where a single light is controlled from two separate locations. Black (hot), white (neutral), and red (traveler) wires are connected via wirenut splices in the ceiling junction box, with proper grounding implied. The diagram clarifies how the feed enters, splits at the light box, and routes through both switches using common and traveler terminals.

Used on DIY electrical guides, home improvement blogs, and contractor training materials to teach safe multi-location lighting control; matches user intent for troubleshooting, installing, or understanding residential 3-way switch circuits.
