This is only a wiring schematic and not the actual wiring method used for 3 way switch installations. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together.
3 Way Light Circuit Wiring Diagram A Wiring Diagram Images
3 way circuit wiring diagram. The black line wire connects to the common terminal of the first 3 way switch. Take a closer look at a 3 way switch wiring diagram. With these diagrams below it will take the guess work out of wiring. The steps above describe installing a 3 way switch and provide a 3 way switch diagram utilizing one light fixture. If you intend to add multiple lights with a 3 way switch use the 3 way switch for multiple lights diagram. If more than three switches are needed simply place more 4 way switches between the three way switches.
3 way switch schematic wiring diagram. Typical 3 way switch wiring nm cable. Below is a simple 3 way schematic that can be applied to all three way electrical light switch connections. Assortment of fender telecaster 3 way switch wiring diagram. To illustrate the wiring of these 3 way switches switch boxes and fixture boxes are not shown but are obviously required for every application. The basic 3 way switch wiring diagram this is the most common and the easiest wiring diagram to follow of any of the wiring diagrams for a 3 way switch circuit.
This wire diagram shows the wiring for source power into the first three way switch then 3 wire cable to the next 3 way light switch and then on to the light or light fixtures. 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. Traveler wires are interchangeable. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. A wiring diagram is a simplified conventional photographic depiction of an electric circuit. 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.
3 way switch wiring diagram. Two very old three way switches. 4 way switch wiring 4 way switches provide switching from three or more locations. This might seem intimidating but it does not have to be. Wiring multiple lights on a 3 way 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 can make or break the connection that completes the circuit to the light. Three wire cable runs between the switches and 2 wire cable runs to the light. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. Wiring a 3 way light switch. It shows the elements of the circuit as streamlined shapes and the power and also signal links in between the devices. Two very old three way switches are depicted in the photo above.
As you will see most 4 way switch wiring is placed between the wiring of two 3 way switches therefore a 4way switch is installed with two 3way.
