22 wrz 2024 · A three-way switch controls ceiling lights, fans, or other fixtures from two locations, unlike a single-pole switch, which controls a light fixture from a single location. You can arrange switches to control light fixtures from multiple locations using a three-way or four-way switch.
Three-way and four-way switches make it possible to control a light from multiple locations, such as the top and bottom of a stairway, either end of a long hallway, or multiple doorways into a large room.
Unlike a traditional switch, which simply opens and closes a circuit, a 3-way switch uses a more complex mechanism involving three terminals and four wires. This allows for a variety of connections and combinations, giving you more control over your lighting.

A 3 way switch is a type of electrical switch that allows you to control a light fixture or a group of lights from two different locations. It is commonly used in stairways, hallways, and large rooms where multiple access points are needed to control the lights.
Three-way switches allow you to operate a light, or device such as a ceiling fan, from two different locations. That’s why a 3-way circuit always involves two 3-way switches. Watch our video for a straightforward guide to understanding how a three-way switch works – theoretically.
