Maybe because on the older machines (e.g. PDP-1) they really were toggle
switches?

That would work.

Still, it would be nice to find a front panel mechanical drawing and see what
they are called on the BoM. (I tried to find one for the 11/20 front panel,
and although I found the tech manual for it, I couldn't the print set for the
front panel.)
