(pronounced THREE-way swich)

This is a bit of a confusing term when you first hear it because it seems to be improperly named. A three-way switch is a pair of light switches wired to control the same fixture or group of fixtures. (So wouldn’t you think that it would be called a two-way switch?) Similarly, a four-way switch is a set of three switches wired to control the same fixture or group of fixtures. Whatever — we don’t make the rules.
