Tried some searches but don’t know how to word this properly I guess. So I have 9 switches on the layout now, I want to power them with their own transformer through the constant power pin. Oh, this is all tubular stuff. Do I put the constant voltage pin to the 18v on the transformer and the common (U) to the outside rail? That being hooked up to the rail, will it interfere with the common of the trains transformer. Hope I phrased this properly and sorry if it’s a silly question........
