Abstract

L'invention concerne un actionneur (1) destiné à la commande d'une unité de commutation et comportant un affichage mécanique qui présente une pluralité de fenêtres (10) et une pluralité de surfaces d'affichage (8) visibles à travers ces fenêtres. L'invention porte également sur un appareil de commande électromécanique comportant une unité de commutation pouvant être commandée par un actionneur (1) de ce type. L'invention est caractérisée en ce que les surfaces d'affichage (8) sont reliées à un élément de liaison élastique (9) disposé contre la tête d'actionnement (2) de l'actionneur (1) et que, lors d'un mouvement d'actionnement de la tête d'actionnement (2), elles tournent partiellement autour d'un axe de rotation avec l'élément de liaison élastique (9), l'axe de rotation étant sensiblement perpendiculaire au mouvement d'actionnement de la tête d'actionnement (2), et les surfaces d'affichage (8) étant visibles à travers les fenêtres (10) annulaires ménagées dans la tête d'actionnement (2).
