Idea on Switch Modifications

[eRadicatedZomBiE]

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...

Only Rootwyrm can answer about the mechanics of infinite wear, but it has been my experience that switches fail in many different ways.

With the keyboards that I have owned, far more of the dead switches are due to electrical problems than mechanical parts wearing through.

After you have put in your 50 million strokes, just buy a new keyboard. At some point it isn't worth upgrading the parts.

I will certainly not live long enough to wear out the 4 Model Fs and half-dozen Model Ms that I own.

I believe that the leaf spring inside the switch is likely to break before the coiled spring does.

I had the housing of a switch (the one in the middle) break apart. (Yes, I know the colours are weird. The blue switches look green)
