The white wire of the cable going to the switch is attached to the black line in the fixture box using a wire nut. A wiring diagram is a simplified standard pictorial representation of an electrical circuit.
Lighting Circuit Diagrams For 1 2 And 3 Way Switching
3 way electrical circuit diagram. With these diagrams below it will take the guess work out of wiring. 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. Assortment of 3 way switch wiring diagram pdf. Wiring a 3 way light switch. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box.
Diagram to add an outlet to a 3 way 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. The goal is to place two switches at separate locations which control the exact same device. The first step in any electrical project is to make sure there is no power going to the circuit you plan to be working on. The source hot neutral and ground are spliced to a 2 wire cable that runs to the new outlet. A three way switch is fundamentally different in its operation from a regular two way switch.
Interested in a 4 way switch wiring diagram. The white wire becomes the energized switch leg as indicated by using black or red electrical tape. You must completely forget about the notion of a switch being a simple openclosed circuit and look at the diagram of the circuitry of this modern alternative. It shows the parts of the circuit as simplified forms and also the power and signal links in between the tools. Take a closer look at a 3 way switch wiring diagram. This might seem intimidating but it does not have to be.
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. Here a receptacle is added to the 3 way circuit before the first switch. Basic 3 way switch diagram how to wire 3 way light switch step by step. Typical 3 way switch wiring nm cable. This article explains a 3 way switch wiring diagram and step how to wire three way light switch electrical circuit we have to discuss about what are the three ways for wiring diagram as discussed below and how to connect all the lights and what are the different techniques to join such switches to getour own desired outputs as mentioned below. Traveler wires are interchangeable.
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. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together. 3 way switch diagram 2 above shows the electricity source starting at the fixture. It is not controlled with the switches but is instead always hot. Turn the power off at circuit breaker.
