An electrical wiring three way switch is a device used to control a light fixture or other electrical device from two different locations. It operates on a three-way circuit, consisting of a power source, the fixture, and two three way switches. Each switch has two input terminals and one output terminal, with the input terminals connecting to the power source and the fixture, and the output terminal connecting to the other switch.
When one switch is in the “on” position, it completes the circuit between the power source and the fixture, turning it on. When the other switch is in the “on” position, it breaks the circuit between the first switch and the fixture, but completes the circuit between the power source and the fixture through its own output terminal, again turning it on. This allows for the same fixture to be controlled from two separate locations.
Three way switches are commonly used in hallways, stairwells, and other areas where it is convenient to control a light from multiple locations. They provide greater convenience and flexibility in controlling lighting, and have been an essential part of electrical wiring systems for over a century.
