If I recall correctly, the BCD switch Codan/Daniels used for channel selection in the AC-3e,? CI-BC-4E, and CI-RC-4L is from the Grayhill 26AS22-01-1-16 series.? In order to get a more exact part number, I would need to pull and open a module. Perhaps I can do this by the weekend but no promises.
It appears that NOS versions of this switch -- that should work fine -- can be found on eBay for about $15 to $20, including shipping.? The usual places, such a Mouser and Digikey also carry these switches. You only need modest soldering skills to add the necessary leads, although switches with leads attached seem to be available on eBay for about $40.? When buying surplus switches, be sure that you get regular BCD encoding instead compliment or Gray encoding.
Codan may offer a kit that includes the switch with leads attached and perhaps a matching knob.? However, that is a more expensive option.?
