Abstract

La présente invention concerne un appareil de commutation (10) électrique, en particulier électromécanique, doté d'un entraînement rotatif (30) pouvant être monté ultérieurement. L'espace d'installation nécessaire ne devrait pas être augmenté par le montage ultérieur de l'entraînement rotatif (30). Selon l'invention, un appareil de commutation électrique (10) pouvant être commandé par un élément de commande (16, 17) sensiblement translatoire entre deux positions finales et disposé sur un côté avant (11) de l'appareil de commutation est rééquipé avec un entraînement rotatif (30) changeant le mouvement de commande sensiblement translatoire en un mouvement de commande rotatif. L'entraînement rotatif (30) comprend un premier axe (32) sensiblement perpendiculaire au côté de commande (11) de l'appareil de commutation (10) et un organe d'entraînement (35, 36, 37) en liaison fonctionnelle avec le premier axe pour l'élément de commande (16, 17). L'appareil de commande est pourvu d'un logement pour l'entraînement rotatif de sorte que l'entraînement rotatif puisse être intégré dans l'appareil de commutation (10). Par ce moyen, l'espace d'installation nécessaire pour l'appareil reste identique, indépendamment du fait qu'il puisse être commandé en translation ou en rotation. Un entraînement rotatif (30) comme module correspondant pouvant être monté dans le logement de l'appareil de commutation (10) peut être fabriqué à moindres coûts à partir de quelques pièces.
