3 Way Switching Wiring Diagram. This is the wiring for a dimmer in a 4 way circuit. A 3-way switch wiring diagram is a simple drawing showing how to connect the wires to each of the four screws on the 3-way switch.
I have a light that has two switches controlling it. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. Most likely to be found with wires in conduit.
This might seem intimidating but it does not have to be.
The circuit consists of a two way switch at each end top and bottom switches in Fig 2 and an intermediate switch in the middle. Three wires between the two end switches probably using 3 core and earth cable. I have the understanding of a normal 3 way switch but the extra light has thrown me. First my easy to understand chart helps to identify the 3-way switch system for the application.
