Product Summary

Electrically, a four-way switch has two pairs of terminals which it connects either straight through, or crossed over. By connecting one or more four-way switches in-line with three-way switches at either end, the light can be controlled from three or more locations. Toggling any switch changes the state of the light from off to on, or on to off.

A 4 way switch is interconnection of two or more light switches to control lighting from more than one location. This allows lighting in a hallway or stairwell to be controlled from either end. 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, or either end of a long hallway. These switches are externally similar to single-pole switches, but have extra connections which allow two circuits to be controlled. Toggling the switch disconnects one circuit and connects the other.
