COSMAC Elf switch panel using PCBs

[dwight]

Lf it were mine to make, it would be a spring return
momentary SPDT. NC would be ground and NO would be +5V,
as per the schematic.
I'm not sure what the manual says about it.
It is debounced with a jam latch, as per schematic.

It's an SPDT toggle. Neither the NC or NO pin of the switch should be
tied to ground; it's the common pin that's grounded. So for a toggle
switch, which side is NC and which is NO?

Anyhow, apparently if I'd read it more carefully, it is explained in the manual.
