Now if your "SWITCH" is of the push button type then that is a momentary acting switch. Depending on how the circuit was designed by the manufacture, every time you push the button you are either pulling voltage to ground or sending voltage to certain transistor that will then within the circuit design vary resistance and then voltage output to the face plates. This is why I said I would need to take voltage readings in order to design it to work right. Now with that said, IMHO just buy a new set, you already invested the time and effort to install the face plates. You can always use the remaining parts as spares in the event something breaks.
it's a mementary switch i apologize for the redundancy and really appreciate all the comments i was just wondering if i could hard wire it. thanks again.
