Wiring 3 Way Switch With 2 Hot Wires. Three-way wire(which includes red, black and white wires) runs from the switch on the left to the switch on the right, with the white wire carrying There are several other ways to wire three-way switches to a light. Each switch box has a hot line coming in.
If one of the black (hot) wires does have power, then that is the wire for the "always on" plug. I thought only one should be hot??? Each three-way switch has two hot terminals, like a conventional switch, as well as an extra terminal that connects it to the other switch.
Flip the switch to make sure the light turns off and on.
I've read up on three way switches, and have replaced a few over the years.
