4 Way Switch Wiring Diagram With 2 Light

This 4 way switch diagram 2 shows the power source starting at the fixture.

4 way switch wiring diagram with 2 light. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit. Place all the 4 way switches between the two 3 way switches. 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. Conventional 4 way switch wiring.

A 4 way switch must be wired between two 3 way switches as shown in the diagrams on this page. This 4 way switch diagram 1 shows the power source starting at the left 3 way switch. Quick 4 way light wiring. Multiple light wiring diagram.

A 4 way switch has five terminals. If you want more than three locations to control the lights you will need a 4 way switch for each of those extra locations. A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch. A 3 wire nm connects the traveler terminals of the first 3 way switch and the first 4 way switch.

The source is at sw1 and 2 wire cable runs from there to the fixtures. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut. It is used for carrying the power from the far end of the final 3 way switch back to the light device being switched. This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following.

A third conductor passing through the junction box with the 4 way switch will not be connected to the 4 way switch. This diagram illustrates wiring for one switch to control 2 or more lights. 4 way switches have four terminals each with two pairs of travelers one set usually black and one set usually brass color. Power from light fixture to light switch.

In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. I have a few of the most common ways in wiring a 4 way switch to help you with your basic home wiring projects. The black line wire connects to the common terminal of the first 3 way switch. For a 4 way light circuit to work you need two 3 way switches and at least one 4 way switch.

A four switch configuration will have two 3 way switches one on each end and two 4 way switches in the middle. A two wire cable c2 is run from the light to the first switch sw1 and a 3 wire cable runs between all the switches. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. Typical 4 way switch wiring nm cable.
