I might be able to fix the switch if I can remove the wire hoops and
find a suitable replacement ferrite, though that seems at least as
difficult (possibly moreso) as finding replacement keyswitches.
I'm actually tempted to get a Nd magnet and a few small ferrites and try
this on a breadboard. Seems like it might be a fun experiment to do in
an evening and then write up (or demonstrate in a video).
Look for RF cores, not ones for shielding. These are usually easy
to saturate.
