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 way switching old cable colours.
Three Way Switch Description
Three way lighting circuit diagram. Three way switching old cable colours. The 3 way lighting circuit which is often referred to as the two way and intermediate lighting circuit is a common arrangement usually found in large houses. A three way switch is fundamentally different in its operation from a regular two way switch. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. 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. The most basic circuit with only two wires at the switch.
This might seem intimidating but it does not have to be. Two way switching 2 wires. If you are familiar with wiring a two way lighting circuit then the addition of an extra switching point will not be much of a problem. These diagrams show various methods of one two and multiple way switching. In this diagram the electrical source is at the first switch and the light is located at the end of the circuit. 3 way switch wiring diagram.
Wiring diagram 3 way switch with light at the end. Earth wires are not shown. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. L and n indicate the supply. 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 black and red wires between sw1 and sw2 are connected to the traveler terminals.
This allows a single light to be turned on or off from any of the switchesthis page shows it wired in the new cable colours if your house has the old colours you want to go here. With these diagrams below it will take the guess work out of wiring. Switches are shown as dotted rectangles. Knowing how to wire a three way lighting switch comes down to understanding the operation of this contraption. Take a closer look at a 3 way switch wiring diagram. 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. Turn the power off at circuit breaker. Three wire cable runs between the switches and 2 wire cable runs to the light. Basic 3 way switch diagram how to wire 3 way light switch step by step. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. 3 way switch diagrams for multiple light fixtures.
This allows a single light to be turned on or off from any of the switchesthis page shows it wired in the new cable colours if your house has the old colours you want to go here. It is true that there are several wiring configurations for wiring 3 way light switches and all of the wiring configurations will depend on where the incoming circuit power is located and once that is identified the rest of the three way wiring connections are straight forward.
