One Light Three Way Switch Wiring Diagram
This might seem intimidating but it does not have to be.
One light three way switch wiring diagram. The black and red wires between sw1 and sw2 are connected to the traveler terminals. The fixture s hot wire connects. Three wire cable runs between the switches and 2 wire cable runs to the light. 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.
3 way switch wiring diagram depicting all wires in the ceiling junction box. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. 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 switch can make or break the connection that completes the circuit to the light.
With these diagrams below it will take the guess work out of wiring. 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 wire diagram power to light switch in this diagram the incoming hot wire attaches to the first switch s common dark colored terminal. The two hot wires of three wire cable connect to a pair of brass colored traveler terminals on each switch.
For a 4 way light circuit to work you need two 3 way switches and at least one 4 way switch. Three wire cable runs between the switches and 2 wire cable runs to the light. A three way switch is fundamentally different in its operation from a regular two way switch. Take a closer look at a 3 way switch wiring diagram.
