First of all we need to go over a little basic terminology on switches. Four way switches how they work duration.
The Best 3 Way Switch Explanation Ever
Different ways to wire a 4 way switch. Wiring a 4 way switch is simply adding a switch to an already existing 3 way switch circuit. How to wire 4 way light switch and intermediate switch in this video we explain how four way intermediate switching works to connect a light fitting which is controlled with three or more light. Fix it home improvement channel 161354 views. Starting with safety and understanding 1. A 3 wire nm connects the traveler terminals of the last 4 way switch and the second 3 way switch. At the lights the hot source is spliced to the black wire running between lights it does not connect to the lights.
Turn on the light or device being controlled by the 3 way switches if you already have them. Here 3 wire cable runs between l1 and l2 2 wire cable runs from the last light to sw1 and more 3 wire cable runs from sw1 to the 4 way switch and then to sw2. The common terminal of the second 3 way switch supplies line voltage switched from. Return to location you plan to wire to verify that there is no electric flow to that device. Wiring a 4 way switch 4 way switch diagram four way switch wiring duration. If more than three switches are needed simply place more 4 way switches between the three way switches.
4 way switch wiring 4 way switches provide switching from three or more locations. As you will see most 4 way switch wiring is placed between the wiring of two 3 way switches therefore a 4way switch is installed with two 3way switches. Here two 4 way and two 3 way switches are used to control lights from four different locations. T2 from that switch is wired to t1 on the second 4way and t2 connects to the travelers on sw2. How to wire a 4 way switch. The two 4 ways are located between the two 3 ways and the traveler wires run from sw1 to t1 on the first 4 way.
4 way switch wiring with four switches. If the device is still. A 3 wire nm connects the traveler terminals of the first 4 way switch and the second 4 way switch and so on. This allows you to control a load from other locations in addition to the 2 locations that a 3 way circuit provides. The traveler wires are interchangeable on each switch. Turn off electric power.
