Any guess what's up with this wiring?
This is how my light switches are wired. The left switch successfully works a hall light. The right switch is supposed to work a porch light, but doesn't seem to do anything.
And why there are three lines to two lights? None of these are three-way switches.
@TimeLime my guess is the right line is the power coming in from the breaker, the middle goes to your hall light, and the left one to the porch. As for what's wrong, I'd hazard it's something with how the two live wires are bussed together on the right switch.
Should probably write the disclaimer that I'm not an electrician.
@ThinSlicely hey, I'm posting here so I don't have to talk to an electrician!
I'm surprised there's no point where the white wires touch a switch. Or I guess the right switch could be broken.
@TimeLime Ah yeah, there's no need for the white wire to touch the switch! You only need to cut/complete the current loop at one point to stop/start current flowing through the bulb.
I believe you typically put the switch on the black/live wire so that the light fixture is pulled down to the neutral/white voltage (i.e. 0V) when the switch is off. Makes it safer to change bulbs and such.
