Today I'll show you how to Install a 3 way light switch in a 60 second #short video. Wiring two 3 way light switches to control one or more lights from two locations is really quite easy. I'll show you the most common method which is when the feed enters one box and the light exits the second box.

Electrical box at switch #1 will have the following:
14/2 cable with a black/white/bare wire power feed to the box.
14/3 cable with a black/red/white/bare wire between switch boxes.

Electrical box at switch #2 will have the following:
14/2 cable with a black/white/bare wire to the light(s).
14/3 cable with a black/red/white/bare wire between switch boxes.

Connections: (box #1)
White wires tie together with a wire nut or other approved connection.
Bare ground wires tie together with a wire nut or other approved connection with a tail left which connects to the green screw on the switch.
Black feeder wire connects to the common (black) screw on the switch.
Red and Black wires between switch boxes (travelers) connect to the two bronze screws on the switch.
Connections: (box #2)
White wires tie together with a wire nut or other approved connection.
Bare ground wires tie together with a wire nut or other approved connection with a tail left which connects to the green screw on the switch.
Black wire to the lights connects to the common (black) screw on the switch.
Red and Black wires between switch boxes (travelers) connect to the two bronze screws on the switch.
