Abstract

L'invention concerne un dispositif d'entrée comportant une carte de circuit imprimé (5) sur laquelle sont disposées plusieurs bobines (L1-L8) qui forment chacune conjointement avec un condensateur (C2) un circuit déterminant la fréquence d'un oscillateur (1). Les bobines (L1-L8) sont réparties le long d'une trace (K) qui peut être également une trace circulaire. Une pièce magnétique mobile (M) peut être décalée par rapport à la carte de circuit imprimé (5). Au moins une autre pièce magnétique stationnaire (M1-M8) est fixée sur la carte de circuit imprimé (5) en regard de la pièce magnétique mobile (M).
