4 Way Switch Wiring Diagrams

This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches coming after. Two-wire cable is run from the light to SW1 and 3-wire cable runs between the three switches.

Four way switch wiring diagram with the LINE and the LOAD in the same switch box. In the diagram above splices are made and a three conductor cable is installed between all the switches. The white wire needs to be re-identified as a hot conductor because it is not being used as a neutral in this installation.

At the center box, with a four-way switch, black and red from the first box goes to two terminals with the black and red going to the third box to the other two terminals. The white neutral splices to the white to the light. In the third box, black and red are travelers with white going to the common.

4 way switch wiring diagram with the power feed through the light : In this method the power source is at the light fixture and the two 3-way switches follow after the light fixture. A 2-wire cable is connected from the light fixture to the first 3-way switch. The hot source is connected to the common on the first switch and the hot terminal on ...

3 Way & 4 Way Switch Wiring Diagram

4-Way Switch Wring Diagram. A 4-way switch is always placed in between two 3-way switches. Watch the 4-Way Switch video below and pay attention. If you understand how to wire a 3-way switch, you'll have no issues with a 4-way switch. You can have an indefinite number of 4-way switches in a circuit. They all must be between the two 3-way switches.

Conventional 4-Way Switch Wiring. 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. In the diagrams below, the first switch (3-way) common terminal connects to ...

How to Wire a 4 Way Switch (with Pictures)

Attach the black and white/blue traveler wires entering the 4-way switch box to the "in" terminals, often the top terminals on the 4-way switch - black on the left top pole and white/blue on the right top pole. Some 4-way switches may have the "in" and "out" pairs opposite each other, rather than top and bottom.
