A3-way switch is built differently than a conventional light switch. For starters, 3-way switches are not labeled “ON” or “OFF.” They also have three terminal screws or wire holes plus a ground screw. Unlike a single-pole outlet, that third terminal connects to a traveler wire to connect the two switches.

Identifythe travelers. First, the partner switch is the power source. You can tell because its common terminal is hooked directly off a dual receptacle. Unless the receptacle is switched, that must be the supply. The other two screws on the supply 3-way are the travelers and there is a black and red wire on them.

First pick your wire type. You need to either use a 14-3type NM cable, or a 12-3 if you’re connecting to 12-gauge wire. The breakerwill affect this decision as well. Once you’ve correctly identified your wires, feed the cablesto the light. If you already have a space for the wires to go you canfollow that path.
