Abstract

L'invention concerne un appareil de commutation (1) comprenant au moins deux contacts de commutation (3, 19), un mécanisme d'actionnement (18, 26, 48) couplé à ceux-ci et un élément d'actionnement (4) couplé à ce dernier. Cet appareil de commutation (1) comprend en outre un dispositif de verrouillage (24) destiné à fermer l'appareil de commutation (1), et qui, en position verrouillée, est conçu pour bloquer l'élément d'actionnement (4) et/ou découpler l'élément d'actionnement (4) du premier mécanisme d'actionnement (18, 26, 48). À cet effet, l'appareil de commutation (1) présente un élément de verrouillage (15) agissant sur le dispositif de verrouillage (24) ou faisant partie de ce dernier, dont la position est directement ou indirectement dérivée d'une position des contacts de commutation (3, 19). Cela permet de fermer le dispositif de verrouillage (24) lorsque les contacts de commutation (3, 19) sont ouverts/fermés et d'en empêcher la fermeture lorsque les contacts de commutation (3, 19) sont fermés/ouverts, même si l'élément d'actionnement (4) se trouve en position ARRÊT/MARCHE. Concrètement, lorsque les contacts de commutation (3, 19) sont fermés/ouverts, l'élément de verrouillage (15) s'étend jusque dans le chemin de déplacement d'une première partie saillante (11) du dispositif de verrouillage (24).
