How to handle a circuit switched by ground

woody_unreal:
you may even try a actual picture :slight_smile: it may be easyer to just find a walwart that is 4.5v :slight_smile:

I will post an actual picture but it sounded/sounds to me like JimG was on to something!

As for finding a wall wart that is 4.5v, that's what I thought. Then I found that a wall wart for 4.5v can output +/- roughly 3v in either direction! Hence the vreg. I don't think the problem lies in my vreg, though.
