Abstract

L'invention concerne un composant électronique fonctionnel comprenant : un corps d'actionnement pouvant tourner autour d'un axe central de rotation ; un rotor ; un mécanisme de transmission ; et une unité de génération de force de résistance. Le mécanisme de transmission fait tourner le rotor par transmission, au rotor, du déplacement du corps d'actionnement associé au mouvement rotatif du corps d'actionnement. L'unité de génération de force de résistance génère une force de résistance par rapport à la rotation du rotor, et peut modifier l'intensité de la force de résistance par commande électrique. Le corps d'actionnement et l'unité de génération de force de résistance sont juxtaposés dans une direction orthogonale à l'axe central de rotation. Ce composant électronique fonctionnel est capable de changer la sensation de fonctionnement, tout en supprimant une augmentation de taille.
