the keycap having a long plunger on it.
There's NO way chips can get to the working bits in normal use.
However, you may have to vacuum the chips away - inverting the keyboard
to spill them out will likely cause some chips to fall where they
shouldn't.
Most importantly, even at the limit of a key's travel, there's still a
fair bit of room between the bottom of the key and the base. A fair
bit of swarf can get in there without affecting "feel".
This explanation is poor, I know. Just find one and pry a keycap off.
You'll see immediately.
