Also know, how can you tell if a 4 way switch is bad?
If you get a light in any combination in both up and down positions of a 3-way, that switch is good. If it meets the above "all or nothing" test, then that 3-way switch OR the wire from it to the first 4-way switch connection is bad OR that first 4-way is bad.
Likewise, how does a 4 way switch work? Four-way switches are used to control lighting from three or more locations. There are four terminals that provide two sets of toggle positions on a four-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals.
Accordingly, when should you use a 4 way switch?
You use 4-way switches in situations where you want to control a light or other fixture from more than two locations. For example, the second-floor hallway lights in my own home are controlled at four different locations. To accomplish this, you must have two 3-way switches and two 4-way switches.
What does a 4 way light switch look like?
4-way switches have four terminals each with two pairs of travelers (one set usually black and one set usually brass color). A four switch configuration will have two 3-way switches, one on each end and two 4-way switches in the middle.
