Electrical Switch Wiring: Wiring 3 way rocker switch



Question about Wiring 3-Way Switches:

I have wired my three way switch the way you have shown in the 3-way switch wiring diagram and for some reason I am not getting power through to the light on one side of the switch and I'm not sure what to do about it.

Please help me. I am using the wide button rocker switches and each has a black screw in the same position and two brass screws the same as in the 3-way wiring diagram.

The switch does not work no matter what order I put the wires in.

Thank You,
John R.



Hi John - Great Electrical Repair Question!
When looking at the rocker switches it is very easy to use the wrong terminal for the point or black screw, especially if you're using the push in terminals on the back. Remember that the brass terminals are for the travelers between your two 3-way switches, the black terminals are for the power and the wire leading to the fixture. From here I don't know which wiring scenario your actually using, where your power originates at or where your switch leg for the light fixture is located with respect to your layout



If you don't get it working, please let me know more about your wiring layout or which diagram you are using on the website.
