I guess i will try and leave it like that unstucked, for 3 days and afterwards replace it if it didnt go away.
Wow! That is horrible! The only thing I can think of would be to soak the switch in acetone. But given how cheap those switches are, I don't think I would risk it. I suspect it would be safe to soak it in acetone but the problem is you can't see what is inside. I would be worried the opposite thing would happen. I would worry a thin film of plastic got deposited on the contacts and then everything would act flakey.

I kind of risk the same thing spraying hair spray on the bed with the probe measuring things. But the good news is I'm spraying down and the switch button is kind of shielded. But I'm going to be more careful going forward!
