First of all, hello there everyone, I'm new to the site and pretty much to custom electronics but I learn quickly and right now I'm in need of a bit of help. My question is probably quite easily answered with "you could just build one yourself" lol, but I want to use a unit I have seen due to its design and I want to know if and how to convert a standard touch activated (Metal panel) home lighting switch so that it can be powered from a 12v supply?
