Thanks Al, I did look at US Digital but didn't find anything that was very compatible with what I already have. The EC35 looked the closest but still at least $186 each by the time you configure it, add in the connector and cable and then I still need to rework the shaft arrangement. So it's not all that much better. It amazes me to think nobody has come up with a better solution for what is essentially a 3 pole rotary switch.
Maybe here is something... What do you think of this one?
