Diagram For Wiring 3 Way Switch

The fixture s hot wire connects.

Diagram for wiring 3 way switch. The black line wire connects to the common terminal of the first 3 way switch. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. Then a 4 wire cable going between the two 3 way switches and then a 3 wire cable going from the switches to the load. 3 way switch wiring diagrams wiring diagram 3 way switch with light at the end.

Three way switch wiring with light middle. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together. The two hot wires of three wire cable connect to a pair of brass colored traveler terminals on each switch. This is the 3 wire cable which you must have to wire a 3 way.

Now discussing 3 way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. 3 way switch wiring diagram with power feed via light. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wire nut. In the above 3 way switch wiring diagram at each switch the black wire gets connected to the copper or black screw.

3 way switch wiring with. 3 way switch wire diagram power to light switch in this diagram the incoming hot wire attaches to the first switch s common dark colored terminal. The source in this circuit is at the first switch and the light fixture is. With these diagrams below it will take the guess work out of wiring.

Power through switch light is controlled by two three way switches with the light between the switches and the power first going through a switch then to the light and onto the second three way switch. The white wire becomes the energized switch leg as indicated by using black or red electrical tape. 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. In the ceiling light fixture electrical box one black wire from a 3 way switch gets connected to the black load wire on the light fixture.

Each 3 way switch in these examples are controlling the power source to the same load. So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire. Take a closer look at a 3 way switch wiring diagram. When wiring a 3 way switch circuit we will be using a 3 wire cable known as romex coming from the source such as the breaker box.
