I have the Happs coin door.... (I bought it new.... its like $100 !!!... but looks VERY good...) - well... basically because I don't know how to make it look good and cover the hole without the coin door....
anyway.... that's not the point...
only the coin door lights needs power.... the ones I got from happs will take like 12V..... I'm currently feeding 9V to it and its fine....
the mircoswitch of the coin door does not need power... but beware... if you look closely, the microswitch for coin door is different than the microswitch you use in joysticks and buttons... and it turns out that the NO, and NC (normal open, normal close) leads are reversed... (at least for my Happs coin door....)
so, when you hook it up, make sure you don't hook up the wrong way....
the mechanical part of the coin door does NOT require power... (I'm talking about the usual quarter validator stuff... but NOT bill validator... that could be different....)
Hope it helps...
