Thanks for your efforts. They seem to be PDP11 types.
Has anybody had any luck with PDP -8 switches.
Has 3D printing been considered.?

let's see if the 7101J50-C's fit, then we can discuss how to proceed.

They are very close, however - they have the bent face-plate, with the latch,
and the triangular side plates with the holes at the tips for the pivots of
the toggle (actuator, is I guess the formal name). They are also the same
size (facing them - i.e. side-side, both directions).
The only thing that's wrong is that the distance between the switch body, and
the top of the bent face-plate, is too far. This, alas, means not only that
it won't fit into existing holder frames on front consoles, but they also
interfere with the installation of the DEC custom toggles (actuators).
However, they are _so close_ that it's possible that C+K can produce some
semi-custom ones with the right distance. (I've had a good look through the
C+K 7000 series catalog, and all of the current snap-in panel ones have the
taller offset.) Maybe they even still have the tooling, and it's only a
Anyway, I will call C+K on Monday, and see what I can find out.
If it helps any, here are what I expect are the pertinent pages from an original C&K
catalog from 1977:
The selection covers two categories, "Rocker and Lever Handle Switches" and
"PC Mounted Toggle and Rocker Switches"
They include all sorts of styles and measurements, so maybe you can discern whether
something changed in C&K's specs from way back when.
If there seems to be something missing or other pages needed let me know.
Pardon the white-balance, I set the camera and thought they were coming out whiter.
