A short overview. I'm trying to power a low power device (5v) inside a light switch fitting. The problem is that there is no neutral wire going into the switch to connect up to some kind of ac-dc power supply as the only wire going in and out of the fitting is the live supply and the load wire to the light fitting. Is there some kind of way to get a small amount of power to run a circuit in there? The only thing I can think of is some kind of transformer in series of the live going in and out of the switch but that seems like a bad idea.
Also there is an earth in there too for safety reasons but I know that's not usable. Just thought I'd add that before someone tells me my house will burn down.
