[sdiy] source for thumbwheel switches?

[J P]

A man has a cool synthesizer called the Borgfotron...  some of you might 
have heard of this? ;-)

He used some nifty thumbwheel pushbuttons on that synth.

I would like to employ something similar....  but all the pushbuttons I can 
find are for digital systems...  I would prefer to use analogue routing as I 
haven't the understanding of a digital system that would function that way, 
nor do I want to try to figure that out...

Anybody know where those are sold?
