I have a 5yo Cherry MX keyboard, and the rarely used keys (Scroll Lock, Pause, numpad) have a somewhat more defined feeling when they actuate than the most commonly used ones. The difference is subtle, but it's there.
- londons_explore 4y agoThat's probably the spring mechanism wearing out - the actual electrical part is still working properly.
- Majromax 4y agoThat's also the part that isn't worn out under this hall effect approach; the keys are magnetically levitated.
- londons_explore 4y agoUnfortunately a magnetic approach alone won't easily give a suitable force Vs displacement curve for a keyboard. The affirmative 'clunk' feeling as a key goes down isn't easy to replicate with fixed magnets
- lsaferite 4y agoThe key stems in a hall-effect key switch still use a spring. The magnet is not providing any (effective) movement resistance or levitation. It's there simply to provide the magnetic field for the sensor to measure.
