Abstract

The input device has a printed circuit board (5) to which a plurality of coils (L1-L8) has been fitted which, together with a capacitor (C2), each form a frequency-determining element of an oscillator (1). The coils (L1-L8) are arranged so as to be distributed along a path (K), which may also be a circular path. A movable magnet portion (M) can be displaced relative to the printed circuit board (5). At least one further stationary magnet portion (M1-M8) is mounted on the printed circuit board (5), which is opposite the movable magnet portion (M).
