Can anyone recommend suitable rotary switches for either the A (vertical)
or B (angled) configuration?
Unfortunately I don't have any leads on a modern equivalent.
(Just the fairly useless DEC part numbers.)
The construction is dead simple, though. Essentially, mine are
a set of reed switches mounted at 36 degree intervals, a couple
of end plates, and a central shaft with a magnet on it. Some
detents which make the shaft tend to want to stay where you
put it. The newer ones presumably used an angle of 30 degrees
instead of 36.
It's probably achievable to create something with a 3D printer
and some modern reed switches that would fit the original form
factor.
