A 3-way switch is a type of electrical switch with three terminals, used to control a circuit from two different locations. It's a single-pole, double-throw (SPDT) switch, meaning it has one common terminal and two traveler terminals that switch between two different circuits. This allows a light or other electrical device to be turned on or off from either of the two switches.
