In this video, we learn how to wire a three way switch. The arrangement should be one turning the light on, one turning it off, and the other turning back on. All of the switches should be wired coming in from the source of the power on a cord. A neutral wire should go through and the hot wire should be connected to the first switch and feed into the second. The brass terminals have traveler wires going from the first switch to the second. These have two terminals on each side where a cable will come in and go out the other end of the switch.
