On a switch, when they say 50 million press guarantee (or something along those lines).
What on the Switch actually fails?
I would assume compressing the spring over and over again, creates a wear on the spring sort of like bending a paperclip back and forth until it degrades and breaks off.
What if on the bottom of the switch where the Spring rests you have a mechanism like that on a click pen that rotates to have the tip out and then retracts. This would rotate the spring a little bit every time you pressed a key, relieving the same spot of having pressure on it and would make the spring last that much longer.
The only downside I see is, it maybe cheaper to just buy a new switch than to add another moving part to it.
If this has already been done or I'm way off of what breaks down in the switch compartment, I apologize.
EDIT: I may have posted in the wrong area...
