• - When wiring a 3-way switch, first screw the terminal screws of the new switch until they are difficult to turn. - Connect the ground wire to the green screw. - Connect the wire marked common to the black or dark colored screw. - Connect the two remaining traveler wires to the two brass or light colored screws. - Connect the wires to screw terminals by slipping the looped wire under the head of the screw. The end of the loop should point clockwise. - Use long nose pliers to squeeze the wire end tight around the screw. - Tighten the terminal screws.

• A 3-way switch routes the current down one of two wires called travelers. When both of the two switches make contact through the same traveler wire, a circuit is made. This is how each 3-way switch can, at any time, turn a circuit on or off. Each switch can reroute the current to make or break the circuit.

Three-way switches are commonly used to control a light fixture from two different locations. For example, a long hallway or stairway might use a pair of three-way switches at each end so that lights can be turned on when approaching one end of the hall or stairway, then shut off from the other end.Sep 10, 2021

Usually when a 3-way switch fails, lights can be toggled on and off at one switch, but not the other. If one of the two 3-way switches toggles the light(s) on and off, the other 3-way switch has probably failed. Follow these steps to find which switch is bad. Toggle each switch until the light come on.

You will need two different types of 14 AWG wire, to wire your three way switch. You will need 14/2 Romex, and 14/3 Romex. 14/2 wire has two power carrying conductors, a black, and a white, plus a bare ground wire.Jan 17, 2019
