Top Notch 3 Way Switch Internal Diagram
The black and red wires between sw1 and sw2 are connected to the traveler terminals.
3 way switch internal diagram. The diagrams below show the conventional wiring for 3 way switches. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. If you have any problems with these switches it may be best to call an electrician.
The white wire of the cable going to the switch is attached to the black line in the fixture box using a wire nut. 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. Take a closer look at a 3 way switch wiring diagram.
Unfortunately not all 3 way switches are wired the conventional way. In the ceiling light fixture electrical box one black wire from a 3 way switch gets connected to the black load wire on the light fixture. For example they can be arranged so that the feed cable runs to the first three way switch then to the light fixture box then to the second three way switch.
Three way switches allow for controlling a light fixture from two separate locations these are usually used at the top and bottom of a flight of stairs or at two different entrances to a room. 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. This 3 way light switch diagram shows connections when the power comes into the first switch on to the second switch and then on to two or more lights switched by the 3 way circuit.

Read the schematic like a new roadmap. 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. Three way switches can be wired in a number of different ways depending on where they are located relative to the light fixture in the circuit cable runs.
