The new three-way switch box has a green screw at the bottom on one side, and a black screw on the other side at the bottom, with two gold-colored screws at the top. The goal is to place two switches at separate locations which control the exact same device. You can use a volt meter, or the non contact voltage detector to trace the wires. Mechanically and electrically this common terminal is connected internally to one of the other two brass screws, called the traveler terminals. The current enters the light box on a black wire, as it always does. The travelers from one 3 way can be wired to either terminal in a pair, but don't mix up the pairs on the 4 way or the circuit won't work properly.

If you understand the fundamentals of the circuit itself, the possibilities are endless. Three-way switches have different methods of connection, depending on the brand of the switch. Three-way switches allow for controlling a light fixture from two separate locations, these are usually used at the top and bottom of a flight of stairs or at two different entrances to a room.

Take your time, mark the wires properly and you will not only be successful, you will stay sane. The diagrams on this page illustrate connecting multiple lights in 3 way and 4 way switch circuits. Notice the pattern is very similar, but the color code is a little trickier. The line wire is the one that is hot all the time. In the above picture, white is always neutral, while black or red may be hot.

Imagine my frustration after checking my wiring three times, I checked the three-way switch to determine it was a normal single pole, on-off two-way switch. If not, one of the travelers is interchanged with the power here. Click Image or to enlarge Diagram Option 3.

You can observe how the schematic look of 3 way light switch. Here is an example of a light in the middle of the run. Three-Way Switch Wiring Source in Middle In this arrangement, the source for the circuit is at the light fixture which is located in the middle of the circuit. In this circuit, the source hot is connected to the common terminal on the 3 way switch in the first box. For circuits with only two switches, just ignore the 4-way switches in the above figure. This common terminal is always connected internally to one but only one of the traveler terminals; which one is dependent on whether the switch is up or down.
