I am putting two red on/off’s in my master bath - one for the vent fan and one for the additional bathroom lights, but am not having any luck getting them to work. My voltimeter tests seem appropriate so I don’t know what’s wrong. Below is a rough sketch of the wiring in the gang.
Update: jumping the line and load screws while it was hot for a second allowed it to turn on and function. Resetting the breaker killed it again. I have NO idea what that means.
e: and then switching the light off kills the switch, so this must mean they somehow aren’t getting a constant current
