I have a BA11-M box with the usual front panel control, however it was
damaged and all three switches have been sheared off.? The LED's and the
circuit card that connects to the power supply appear to be OK.? I would
like to repair it and put it back into service.? Is there a replacement
for those switches?

Hi Doug,
It might be cheaper to get a BA11-N and use them. The BA11-M panels are
very difficult to find,

In general, many old switch patterns are still made. Often,
they have a manufacturer's name and part # on the body of
the switch. Some common makes from back then were C&K and Alco.

Good advice, I went and looked at another box I had and the switches are
indeed C&K models 7101 and 7108.? Looking on ebay since they are
obsolete, finding the model with the paddle actuator will be the trick.

You should really get on Digi-Key or other distributor who
has a good web site and see if you can find a new model that
fits the same mounting hole and PC board pattern. Even if
C&K obsoleted the exact model, they very likely still make a
compatible part. Digi-Key shows 408 items when I search on
"C&K 7101". Some of those REALLY look like stuff I remember
in DEC equipment.

In case anyone is interested I have put up the STL and parametric scripts on Thingiverse
for a project to build a replica PDP-11/03 console with the same look and feel as the
original
(following the 6-foot Rule) for an MDB backplane I acquired from a cctalk listmember.
If you have missing or broken switch paddles on your 11/03 or 11/05 then this might be of
use to you. Also included is the LED receptacle used on the 11/03 and 11/05 and I think
(but am not certain) the PDP-8/E, as is currently being discussed.
Being parametric you can adjust for different C&K switches, or other brands if you
like.
You will find it at https://www.thingiverse.com/thing:2829191
