The permanent live supply, typically brown in modern European installations, must be connected to the common terminal of the first switch. When installing the second switch, the travelers from the first switch are connected to the two traveler terminals, and the switched live core for the light is connected to the common terminal.
Wiring Two Way Switch Hallway Lighting Step by Step
This configuration, often called a three-way switching arrangement in the UK, uses an additional traveler wire compared to a standard single-pole setup. The protective earth conductor, usually green and yellow, must be secured firmly to the back box of both switches and the light fixture itself.
Once wired, a final test involving checking continuity and verifying correct operation from both switch points ensures the installation meets basic electrical safety standards. Understanding Two Way Switch Wiring Fundamentals The term two way switch refers to the ability to control a single light fixture from two distinct locations, not the number of electrical poles the switch possesses.

Unlike a standard on/off scenario, the circuit’s live feed can enter at either switch box, making the layout flexible for different architectural plans. Properly identifying the cores—live, neutral, and the two travelers—is critical before any connections are made.
