A three-way light switch allows you to control a light source from two different locations. It involves two switches and a traveler wire that connects them. Here’s a simplified explanation: 1. Connect the power supply to the first switch's common terminal. 2. Use the traveler wires (usually in red) to connect the traveler terminals of both switches. 3. Connect the light fixture's wire to the common terminal of the second switch. Ensure the circuit is grounded for safety. Always turn off power at the main breaker box during installation for safety.
