Abstract (en)
[origin: WO8502487A1] Key with non linear travel-force characteristic provided with a motionless part (3), a movable part (1) moving relatively with respect to the motionless part (3) when the key is depressed, as well as switching, respectively detection elements using the relative displacement. The aim of the present invention is to form between the motionless part (3) and the moving part (1) a magnetic circuit which sets, at least in part, the travel-force characteristic and of which the ferromagnetic elements are coupled on one hand with the motionless part (3) and on the other hand with the moving part (1), at least one ferromagnetic element being comprised of a permanent magnet.
