Me too, so I've uploaded some pictures of the knitter switches, as I used 
them. They're pretty small, so I mounted them to small PCB's to make them easier 
to handle. the center wire with green on it is a common ground.

Each clockwise 'click' is a momentary close across the common ground and the 
left pin, a counterclockwise 'click' is a momentary close across the right pin 
and ground. As I said, you have top go a little slowly when making big 
changes, or you miss clicks.

The radio panel is currently a little more advanced than in the pic I 
uploaded - I have added knobs, and across the bottom below the displays there are 
three more knobs - OBS1, OBS2 and HDG. That leaves me enough free inputs (the 
ribbon cable carries 32) for three more rotaries or six more switches. Not sure 
what they'll be yet.
