As mechanical switches make or break contact, there is a certain amount
of "bounce", where the make or break is not a single concrete event,
but a transition of short make/break events and a lot of noise. In
the circuitry that they drive is "de-bounce" logic. I suppose it is
possible that as a switch ages, the amount of noise that occurs during
the make/break event may go up sufficiently to overload the debounce
logic. Or maybe not. I'm no hardware designer, so perhaps I'm soaking
wet.
