that go with the handles? Are they special?
I have worked mostly with various PDP-8 switches, and the 11/70
switches. The PDP-8 switches are nothing unusual, for the time, but I
don't know where one would find quantities of them now. The 11/70
switches are rather ordinary C&K switch bodies with uncommon, but
standard, squarish stamped sheet-metal snap-mounts. New C&K switches
are a few dollars each, unless you can find them surplus (which I did
at the Mansfield Hamfest last year, at least for the non-momentary,
snap-action switches for my 11/70 panel).
I don't know how to describe the older switches, except to say that
they were the rather common slide-switch type of the era, with the
bakelite slide and square stem that is topped by a ridged curved
actuator area. Lots of them were used for power switches for 1960s
and 1970s appliances. The reason the DEC switch handles were these
odd levered affairs was to fit over an ordinary switch.
Personally, I could use some 11/70 switch covers - I have a panel
with _zero_ actuators. At the moment, I have standard C&K black
paddles on them, which is unaesthetic, but functional.
If 11/70 actuators were to be made, I would probably be interested,
but I'm unconvinced that at present prices, it's economical to make a
hobbyist run of them. Perhaps in the medium-term future, should
fab-at-home-type hardware continue to drop in price, the equation will
look more favorable, but right now, I don't think it is.
