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.

I looked at the schematic pdf and it looks right.
The ground lead is the NC.
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.
