how are they pushed in? do you have a photo or video of them in action?

my tvs growing up had a potentiometer bank behind the channel switcher
button panel. you pressed the panel in to make a drawer the size of
the panel pop out, and then you turned the potentiometer with your
thumb to tune into the channel. so maybe that's similar enough for you
to use this idea.

if the mini potentiometers are supposed to be shafts coming out of a
hole in the front panel, and you can press them in to make them
ineffective, then you might want a ballpoint pen mechanism.

(Here’s a fairly cringe video of the core in action, with a lot of extra info about the board layouts, etc — https://www.youtube.com/watch?v=lbtxMdQE64A) I’ve got the core circuitry (48 separate synthesizers) and much of the downstream circuitry (resonators, etc) designed, built and tested, and I am currently trying to lay out the panel.

The original had these nifty retractable mini pots that can be pushed in flush the panel when not being used.  I cannot seem to find anything similar on the internet.  I was wondering if any of you had any inside track into where one might be able to procure such a thing.  I need a dozen of them, and I’d prefer if they were PCB mount, but that’s not strictly necessary.
