After a long and circuitous search I have found a supplier for the switches on our Regency Dash and Side Console. My various switches have a few that are loose in the panels because the small mounting tabs in the back have broken off. The switch itself works fine. The switches appear to be Carling brand however these were made by Carling for Sprague Devices, the maker of our air powered wipers and parts of the air powered cruise controls. You can find the current supplier at www.msfoster.com who supplies a wide variety of switches to the RV industry. The ones in my coach are the 511 series.They have a set of pdf documents that describe the switches that can be downloaded.I plan to call tomorrow to see what I can get from them.
