[GreenKeys] Dry contacts

[Nick England]

Good comments on the M14 keyboard thread. You may also run across
gold-plated contacts on M28 keyboards and TDs used for low-level signaling.
+/-6v, 80uA.
You can use these on 60ma loops but you’ll never be able to go back to
low-level after the gold has been blasted away….
