To wire a 4-way switch configuration, you'll need the following components: One 4-way switch. The centerpiece of the setup, the 4-way switch connects two 3-way switches and allows you to control the lights from multiple locations. Two 3-way switches. The 3-way switches work in conjunction with the 4-way switch to complete the multi-location.. 4-Way Switch Wiring 3 Switches. 4-way switches have four terminals each with two pairs of travelers (one pair usually black and and the other pair brass color). A three switch configuration will have two 3-way switches, one on each end and one 4-way switch in the middle. In the diagrams below, switch 1 common terminal connects to line voltage.
How Does a 4-Way Switch Work? The 4-way switch works by connecting two three-way switches together.
