What wires go where on a 3-way light switch?
With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit’s power is turned on, any of these may be “hot,” depending upon how the switches are toggled.

Where does the neutral wire go on a 3-way switch?
The other wires in a circuit with 3-way switches are the neutral (usually white) and ground (usually bare copper or green). The neutral wire bypasses both 3-way switches but connects to the light fixture. The ground connects to the ground terminal on each switch and to the light fixture.
What happens if 3-way switch is wired wrong?
Finding the common wire: When wiring a 3-way light switch, you’ll need to find the common wire and connect it to the common screw. If you don’t correctly connect this wire, then your lights won’t work from more than one switch.
What is the white wire in a 3-way switch?

How to wire a 3-way light switch?
– 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.
How to troubleshoot 3-way switches?
[Solution] How to Troubleshoot a 3 Way Switch TURN OFF THE POWER AT THE CIRCUIT BREAKER Remove the 3 wires from each of the switches and make sure that none are touching anything.
