A two-way switch connection allows a light (or load) to be controlled from two different locations. It uses two switches connected by “traveler” wires and a common wire. When either switch is toggled, the circuit is completed or broken, turning the light ON or OFF. This type of wiring is commonly used in staircases, hallways, and large rooms for convenient control from multiple points. br br br ⚠️WARNING... br br The videos are for educational purposes only.
