Abstract

L'invention concerne un dispositif de sélection de mode de fonctionnement grâce auquel la fiabilité de contact n'est pas réduite pendant un long moment si le dispositif est fréquemment utilisé et grâce auquel une sensation prédéterminée obtenue en faisant cliqueter le dispositif peut être maintenue. Dans le dispositif de sélection de mode de fonctionnement, un premier et un second IC complet (33, 34) sont placés sur une carte de circuit imprimé (30), et un cadran de fonctionnement (60) muni d'un aimant de sélection de mode (51) qui présente des pôles magnétiques opposés disposés en alternance sur sa circonférence est installé de manière rotative sur ladite carte de circuit imprimé (30). Lorsque le cadran de fonctionnement (60) tourne selon un angle prédéterminé, une sensation de cliquetis s'exerce sur un opérateur, et les pôles magnétiques de l'aimant de sélection de mode (51) sont détectés par les premier et second IC complets (33, 34), afin de produire la position de rotation du cadran de fonctionnement (60).
