4 Way Switch Wiring Diagram With 2 Light

Conventional 4 way switch wiring.

4 way switch wiring diagram with 2 light. A 4 way switch must be wired between two 3 way switches as shown in the diagrams on this page. I have a few of the most common ways in wiring a 4 way switch to help you with your basic home wiring projects. Do you need a 3 way switch wiring diagram. The black line wire connects to the common terminal of the first 3 way switch.

A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch. 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. If you want more than three locations to control the lights you will need a 4 way switch for each of those extra locations. Multiple light wiring diagram.

In the diagrams below the first switch 3 way common terminal connects to. This 4 way switch diagram 1 shows the power source starting at the left 3 way switch. 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.

Power from light fixture to light switch. This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following. It is used for carrying the power from the far end of the final 3 way switch back to the light device being switched. Typical 4 way switch wiring nm cable.

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. A four switch configuration will have two 3 way switches one on each end and two 4 way switches in the middle. Place all the 4 way switches between the two 3 way switches. 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.

This 4 way switch diagram 2 shows the power source starting at the fixture. 4 way switches have four terminals each with two pairs of travelers one set usually black and one set usually brass color. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut.

In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. 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. Quick 4 way light wiring.
