The black and red wires between sw1 and sw2 are connected to the traveler terminals.

Electrical 3 way switch wiring diagram.

A three way switch is fundamentally different in its operation from a regular two way switch. The white wire between switches is not being used as a neutral. Regardless of what 3 way switch wiring diagram you re following you ll need to use a 3 wire cable to connect the two 3 way light switches. Switched outlet wiring diagram.

Now discussing 3 way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire. 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. In the above diagram the white wire must be re identified as a hot wire at each switch location.
