Abstract

L'invention concerne un dispositif de manipulation manuelle (3) à poignée tournante pour des appareils électriques, dont la poignée tournante (5) indique chaque position de commutation et coopère avec l'axe d'entraînement (22) d'un moteur d'orientation (2) et dont la plaque de base (4) montée sur le moteur d'orientation (2) présente une entretoise (41) s'étendant de manière circulaire. Afin d'assurer des positions univoques de la poignée dans différentes positions de montage de l'appareil de commutation, la plaque de base (4) peut être montée dans différentes positions décalées autour de l'axe d'entraînement (22). L'entretoise (41) comprend en outre un premier segment marginal (42) en saillie vers l'intérieur. La poignée tournante (5) coopère avec une plaque d'entraînement (6) pouvant être placée à l'intérieur de l'entretoise (41). Il est prévu sur la plaque d'entraînement (6) un second segment marginal (62) circulaire formé par rapport à la zone marginale en retrait (63). En position ARRET, les deux segments marginaux (42, 62) se complètent sans se chevaucher pour former un anneau de cercle plein. Dans chacune des positions qui s'écarte de la position ARRET, le second segment marginal (62) chevauche ou enserre par l'arrière le premier segment marginal (42).
