That would be fine for the Elf2K, but I want to also use the same
switch panel for a different design that uses a single-ended input
only, so I need it to be a true toggle rather than momentary.

If it was momentary, it would have to be momentary-off-momentary, so
it still wouldn't really make sense (IMNSHO) to refer to the contacts
as NC and NO.
