What is a 4-way switch and how does it work?
A 4-way switch is a type of electrical switch that allows you to control a single light fixture from three or more locations. It typically works in conjunction with two 3-way switches. When you flip any of the switches, it changes the path of the electricity, allowing you to turn the light on or off regardless of which switch you operate. This setup is particularly useful in larger spaces like hallways, staircases, or large rooms where multiple points of access to control the same light are needed.
In a standard setup, the 4-way switch will have four terminals and will connect to the two 3-way switches. The two 3-way switches are located at the ends, and the 4-way switch is placed in between. When one of the 3-way switches is flipped, it sends electricity to the 4-way switch, which then directs the current to the other 3-way switch, completing the circuit and turning the light on or off.
