I see now that my idea would not work on HP calculators and my idea of why keys go mushy. So, just what is it that happens when a key goes mushy?
Two possibilities:
1. The metal arcs that provide the key snap feel have fatigued or cracked. The only repair possible is to replace the keyboard assembly.
2. Depending on the calculator, screws holding the keyboard assembly together have loosened, or in the case of heat-staked keyboards, the heat stakes have started to fail, although this is rare.
What calculator do you have with a mushy keyboard?
