Hi @all,
Hansi is right here, keybeds are actually using two (or three) closing-contacts (often called "rubber contacts") to detect the key pressure and emit the velocity. The velocity is calculated out of the time delta between the events of closing the contacts.
I'm at least not aware of any classical keybed using a different aproach. (apart from very different concepts like in the Roli Seaboard or in like Hansi mentioned strain gauges).
Aftertouch or polyphonic aftertouch is different here. Here a continues value is measured: mostly a pressure depended electrical resistance.
Never the less it's not unusual to call such closing contacts also sensors - especially in the english speaking community. With the German word Sensor mostly a device measruring a continues value and not only closed/opened circuit is meant. So this is IMHO mostly a language and definition topic.
