One Face Button Needs A Really Hard Press Before It Registers
A button that works under hard pressure and misses under light pressure is a worn conductive pad or a contaminated membrane. Cleaning fixes it…

Endurance Tester And Controller Reviewer at Gamepad Tester
Puts face buttons and switches through long endurance runs to find what wears out first.
Oliver runs endurance trials. A controller that feels excellent in the shop can lose its button feel in months, so his testing deliberately pushes mechanical face-button switches, bumpers and triggers through extended, repeated actuation to see how quickly tactility and elasticity fall away.

This is switch bounce from a worn contact: it makes and breaks contact several times in one press. Cleaning sometimes fixes it, otherwise the…
