Components of 3-Way Switch Wiring. All three-way switch and 2-way switch wiring diagrams have the same basic components: Wires consisting of a LINE, a LOAD, a neutral, a pair of travelers, and two 3-way switches. If you are trying to troubleshoot a 3-way switch operation, you will need to identify the function of each wire.

3 Way Switch Wiring Diagram

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! This might seem intimidating, but it does not have to be. With these diagrams below it will take the guess work out of wiring.

Typical 3-Way Switch Wiring, NM Cable. In the 1st diagram below, a 2-wire NM cable supplies power from the panel to the first switch box. The black (line) wire connects to the common terminal of the first 3-way switch. A 3-wire NM connects the traveler terminals of the first and second 3-way switch together. Traveler wires are interchangeable on each switch.

How to Wire a 3 Way Switch

3-way switch (2) 3-way wire (which has black, white, and red (coated) wires – and of course a copper ground wire), electrical boxes of appropriate size to hold 3-way switch and wire; wire cutters and strippers; standard electrical tape; a non-contact voltage tester; 3-Way light switch wiring diagram – See below.

3 Way Switch Wiring Methods: 2 wire and Light Fed S3

Best blog explaining 3 ways with wiring diagrams, photos and 10 different 3 way switch wiring methods used in buildings throughout the US (120 volt). All photos and diagrams may be copied for classroom instruction or personal use.

3 Way Switch Wiring Diagrams

Ceiling Fan 3 Way Switch Wiring. Here, a ceiling fan with a light kit is controlled with two 3-way switches. This is the same arrangement as the second diagram on this page with a fan in place of the light fixture. In this wiring, the source is at SW1 and 3-wire cable runs between each switch and the ceiling fan.

How a 2 Way Switch Wiring Works? | Two

The first way of wiring uses a couple of Two-Way Light Switches with a 3-wire control. The following is the simple schematic of a three wire 2-way switch wiring. You can observe in the schematic that both the COM terminals are connected together. The L1 terminals of both the switches are connected to line (or phase or live) of the AC Supply.
