3 Way Switch

Wiring Three Way Switches

Executive summary By Gary Chappell-Smith

The difference between a standard switch and a three way switch is one additional terminal, or connection. A 3 way switch has 2 terminals that are either silver or brass colored and one terminal that is dark colored. The silver or brass terminals are called travelers or messengers and the dark colored terminal is called the common. In a 3 way switch circuit there will be two 3 way switches and a light or series of lights that are controlled by the switches. To understand this terminal, consider for a moment a standard switch that has only 2 terminals. When wiring a standard switch the incoming power feed (hot) conductor is connected to one terminal (usually bottom right) and the outgoing power feed to the lights is connected to the other terminal (usually top right).

Wiring your house and a Three-way Switch

Executive summary By Robert

Taking the time to plan the wiring of a house always pays off in the long run. Wiring you house this way will allow for a lot of flexibility on where you place your furniture. Canned lighting is appropriate for areas such as the kitchen and family room. Ceiling fans with a light fixture are another option to consider. Once you have made all the decisions on outlets, switches and fixtures it is best to draw out a plan for each room to be wired. The only real difference in a regular switch and a three-way switch is that the two switches on the opposite sides of the room are hooked together with what is called a traveler wire. Then it is just a matter of twisting the wires from the traveler with the regular wires, by matching up the colors and then wiring the switch normally.
