Radams -
I can't be certain, but what you may be describing are the multi-point swtiches that are installed in some coaches. If so, one manufacturer of these switches is Intellitec and that is the brand that is in my Camelot. And if this is what you want, the problem you will face is that they represent a fundamentally different wiring approach from what is conventionally used in 12volt coach wiring. For each switch, you have a single conductor that goes back to a multi-point switching controller. On my coach, there are three of these controllers mounted in a cabinet above the head and they are programable.

and here is a schematic of how they are wired on my coach -

If this is indeed what you are looking for, conversion could be difficult.
Coincidentaly, I could not help but notice the very next post on this forum, where rick.siebert is describing problems he is having with this very same system on his Dynasty......

I guess we should all be careful what we wish for......
