All,
The switch has two wafers (decks A and B in diagram below), six
positions and rotates 180 degrees. The Heathkit part number is
63-212. The diagram gives significant detail as to the functioning of
the switch:

Thanks again, and happy holidays,
M100C

That AR section is a killer, I don't have a wafer with the open circuit
seeking section. But it appears from the schematic that that section is not
used. Is this correct? Are you M1OOC or M100C?
