Could someone explain these to me. If I am understanding this correctly, basically you are adding a neutral wire to a hot wire so that a switch turns off whatever is connected to this? That is as far as I have gotten with it. I posted another post about breaker tips when switch is off. and I am thinking that this is a switch loop. So, if someone could explain this to me so that I can wrap my pretty little head around it that would be great. I have looked on the internet, but... nothing is making sense.
