Headlight Switch - Should it pull out to turn on? 1967 Barracuda

Thanks, all!
That makes sense - switches can probably be purchased from a few places. Nobody is making more knobs, is my assumption.

I'll try 'gentle persuasion' and penetrant spray, then plan to reach behind the panel and release the knob.

If releasing won't work, then I'll destroy the switch but save the knob and stem.

All those photos of the switch are SUPER helpful, thanks!
