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

So the switches got here Friday, and alas, they are _not quite_ the right
thing.

OK, I've cracked the part number code. The things we are looking for are:

Yes. The footprint for the existing front panel PCBs are SPDT.

Ooops; the ones in the PDP-11 front panels (/05, /45, /70 and almost
certainly the /40 too) are SPDT, not SPST (typing too fast, in my excitement
that these have finally been found :-).
I looked at the data sheet for the ones you found, and it's actually a sheet

Casting is one option. Another is CNC out of dense PVC foam.

Any of these C&K-type switches are likely to sell for $4-$6 each as
new (I've gotten fistfuls of similar ones at Hamfests for $0.75 or
less, but it's ve

I think that the switches can be found, but they might be expensive.

But as Noel wrote... the problem isn't the CK switches as far as the "model
number" on them goes. They can be found pretty easy. The problem is that CK
switches used in these systems were custom made wi

kits are even more un-obtainium than the switches

We have plenty of the original bezels, from which it would be easy to cast molds
(the same part is used on the 11/45 and 11/70, unlike the rest of the front
console).
The real issue in any front panel recreation is

But a 11/70 replica needs two physical 'cosmetic elements': proper
switches, and the white bezel/frame. The switches *seem* to be feasible
to produce cheaply (I will know in a month with PDP-8/I switches...). The
white bezel though brings me into unknown territory. 3D CAD (based on

How about making a version for a REAL PDP-11/70 front panel, and one for
a REAL PDP-11/45 front panel, for those of us who have such stashed away

Well done. Have you looked at 3D printing? Not fast, not especially
cheap, but potentially the least difficult developmentally. And once
it's set up you can just let her rip and churn them out.
This is only going in one direction of course... once you have the
11/70 nailed, you *have* to do a pdp-
