First on my bench will be a bunch (8 or so) of Data

machines and a few Nova 2's. I can think of several questions so far
to get me started down the path:
1) A number of the 1200 machines have broken front panel toggle
switches (the switch handle was broken off and lost). Some are spring
return to center, some are just two position. Before I take the
approach of robbing one of the machines for front panel switches, is
there someplace that I can purchase exactly idential (both
electrically and cosmetically) switches, or does some one have donor
switches available for trade? I am a stickler for completely identical
parts, especially for front panel switches :) I was hoping someone had
been down this road before and knew the switch model #'s, etc.
Jay, is this the front panel in the first picture on the wikipedia page?

If those are 'standard size' mini-toggle switches, they may be C&K
switches (typically having a red body).
C&K switches tend to be well-marked with a type number stamped in the
metal, and are fairly prevalent in equipment from the period. I have
their catalog from the mid-70's with full listings. You might have
greater luck finding replacements by specifying the manufacturer & type
number.
If the switch is an unusual pole arrangement or pin-type (PCB mount
rather than wire eyelets) and the body of the switch is still present,
it is sometimes possible to rebuild such switches with the toggle from
a surplus one of more-common type.
