A two-way switch, also known as a three-way switch in some regions, is a common electrical component that allows a single light fixture (or other electrical load) to be controlled from two different locations. This functionality is especially useful in hallways, staircases, and large rooms. At the heart of properly installing a two-way switch system is understanding and accurately implementing the wiring diagram for a two-way switch. The diagram serves as the roadmap for connecting the switches and the light fixture correctly, ensuring safe and reliable operation.
