Diagram Of Wiring A 3 Way Switch

With these diagrams below it will take the guess work out of wiring.

Diagram of wiring a 3 way switch. An example of three way switch wiring with the line and load in the same 4 square electrical box. 3 way switch wiring diagram with line and load in the same switch box. Wiring a 3 way light switch. Interested in a 4 way switch wiring diagram.

The power source also connects the terminal main three way switch and means that you need to have it spliced with a 3 way switch with the wire cable and that you will see the way that there is a neutral terminal with the light. The white wire must be re identified as a hot wire at each switch location. To illustrate the wiring of these 3 way switches switch boxes and fixture boxes are not shown but are obviously required for every application. Knowing how to wire a three way lighting switch comes down to understanding the operation of this contraption.

The travelers actually pass the electricity between the two 3 way switches as well as the 4 way switches shown in the 4 way switching wiring diagrams. This might seem intimidating but it does not have to be. You will see what you need to do when the power is coming to the light switch. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram.

Three wire cable runs between the switches and 2 wire cable runs to the light. Typical 3 way switch wiring nm cable. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit.

With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. This is the 3 wire cable which you must have to wire a 3 way light switch. To wire a 3 way light switch you ll need 2 3 way light switches 2 2 wire non metallic cables 1 3 wire non metallic cable and 2 6 inch grounding wires. The white wire between switches is not being used as a neutral.

3 way switch wiring diagram with power feed via switch. The exact cable you use depends on the gauge of the existing wiring in the rest of the circuit but in most cases the correct cable will be either 12 3 or 14 3. The black line wire connects to the common terminal of the first 3 way switch. You must completely forget about the notion of a switch being a simple open closed circuit and look at the diagram of the circuitry of this modern alternative.

First run a 2 wire cable from the wall power to the black screw on 1 of the switches. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together.
