How To Install A Three Way Switch. A three-way switch is built and wired a little differently than a conventional single-pole light switch. The difference between a three-way switch and a single-pole is that all the single-pole is really doing is breaking the connection between the two wires.

When it comes to installing switches, a three-way switch is more involved than the traditional single switch, but it's nothing you can't handle with a little time and patience.
