There are two clear giveaways that identify a switch as being a three-way type: A three-way switch has four different screw terminals on its body: The green screw attached to the metal strap of the switch is always for the ground wire (this is the bare copper or green insulated wire within the circuit). When the switches are installed, these wires allow electrical current to pass between the switches—or they interrupt the circuit flow to turn the light fixture off. In a normal switch, the two terminals are either connected (as shown) or disconnected. When the toggles are in opposite positions, the circuit is interrupted and the light fixture turns off.

All three-way switch and 2-way switch wiring diagrams have the same basic components: Wires consisting of a LINE, a LOAD, a neutral, a pair of travelers, and two 3-way switches. Because switches do not have white neutral wire connections, the neutral wires at the switch boxes are simply joined together so they pass through, onward to the light fixture box. At this first switch, the black feed wire is connected to the common screw on the switch. Cap the white neutral wires to each switch box. According to the position of its handle, hotness "travels" on to the next switch on one of the two traveler wires.
