I think Stewart is incorrect with the dead zone. The black center rail is indeed hot. Over the plastic magnet portion is a very thin round insulating layer of plastic that fits under the copper jumper preventing a short. The copper jumper keeps the center rail hot. Only one accessory hot wire is attached on the screw. It goes from the accessory hot through the push button to the screw. It’s a momentary push button. No other wiring is needed.
Can you post a photo of the one you are looking at? I have one that's only a year old and it's just like pictured at top, the center rail is plastic. Yes, it has metal center rail joiners that are tied together so it can provide center rail power to both sides of it, but the center rail is plastic on these.
