Out Of This World Hooking Up A 4 Way Switch

Leave the lead on a post that does not have continuity with your initial post.

Hooking up a 4 way switch. Pick one of the four posts of the 4 way switch to hook up the source power. Connect the traveler terminal between all the switches. Does it have continuity now.

Connect the hot wire from the source to the common terminal on the first 3 way and the hot wire from the lights to the common on the other 3 way. If you want more than three locations to control the lights you will need a 4 way switch for each of those extra locations. In the first position the contacts are connected straight through so that the switch has no effect.

A 4 way switch has five terminals. Now flip the switch. Do you need a 3 way switch wiring diagram.

Place all the 4 way switches between the two 3 way switches. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit. Please leave a comment i.

Power from light fixture to light switch. In position two the switch cross connects the contacts on the left with the contacts on the right in an x connection. A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch.

For more than two switches one or more 4 way switches are added between the 3 way switches. The travelers from one 3 way can be wired to either terminal in a pair but don t mix up the pairs on the 4 way or the circuit won t work properly. All you have to do is use two posts of your 4 way switch that alternate continuity when you flip the switch.
