To nemusi byt spinaci.
Problem je v tom, ze zpusob pouziti spinacu neodpovida tomu, pro co jsou navrzene.
Failing switch problem: Omron vs the modern mouse circuit

TL;DR:
-the change from 5v to lower (3.3v) logic voltage and use of the MCUs' higher resistance internal pull-ups (~40k) necessitates a change in hardware design, which manufacturers have not caught up to yet
-the change to faster MCUs and higher polling rates necessitates more advanced firmware logic, which manufacturers have not caught up to yet
-the 'general purpose' switches we have been using don't work well at new voltages/currents/rates, and the ruggedized 50M versions are even more incompatible, and may 'fail' even faster than the lower cycle-life versions
-Micro-load rated switches like D2F-01F or similar may offer better performance and longer electrical life (but possibly shorter mechanical life)
