how do you know if a Light Switch is broken?
I've been installing a light fixture. Wires in the fixture appear to be correctly wired. However, it does not work. I have a Levitron switch which is flickering. A working one in another room does not flicker. Therefore, I think it is a switch issue. I've taken the meter to the wires going into and out of the switch. All appear dead. This leads me to think the switch is broken. How else can I test to see what is broken? (Hopefully, not the wiring)
Have you used the meter properly. One lead to the neutral/white wire or green/bare, and then the other lead to the terminals on the switch to test. Sometimes there isn't a neutral wire in the switch box. In this case, use a nearby ground from an outlet for the testing.
If you don't have power then check the other boxes for your source. Use your meter(continuity) to test the switch without power or wires hooked up. Establish that the switch is wired properly and works well. Switches are real cheap when in doubt
