Abstract

La présente invention concerne un appareil de manœuvre à trois positions. La présente invention comprend un boîtier (10) constitué d'un matériau conducteur. Le boîtier (10) possède une pièce de connexion fixe fixée et raccordée à un côté d'un rail électrique, et des première et deuxième pièces de connexion mobiles (16, 18) de l'autre côté de celui-ci. Une came d'entraînement (20) se trouve dans un espace intérieur (12) du boîtier (10). Des premier et deuxième canaux de verrouillage mutuel (24, 24') sont formés sur les surfaces des deux cotés de la came d'entraînement (20). Une première électrode mobile (30) et une deuxième électrode mobile (40) sont réalisées dans les première et deuxième pièces de connexion mobiles (16, 18) de telle sorte que la première électrode mobile (30) et la deuxième électrode mobile (40) pénètrent à l'intérieur du boîtier (10) et sortent de l'extérieur de celui-ci. La première électrode mobile (30) est verrouillée mutuellement avec la came d'entraînement (20) par un premier mécanisme de liaison (32), et la deuxième électrode mobile (40) est verrouillée mutuellement avec la came d'entraînement (20) par un deuxième mécanisme de liaison (42). Une première broche de verrouillage mutuel (36) et une deuxième broche de verrouillage mutuel (46) agissent dans un état dans lequel la première broche de verrouillage mutuel (36) et la deuxième broche de verrouillage mutuel (46) sont placées dans le premier canal de verrouillage mutuel (24) et le deuxième canal de verrouillage mutuel (24') de manière à être verrouillées mutuellement avec la came d'entraînement (20) dans le premier mécanisme de liaison (32) et le deuxième mécanisme de liaison (42). Conformément à la présente invention mentionnée précédemment, il existe des avantages au fait de disposer d'une configuration relativement simple et d'une longévité ainsi que de performances accrues, car les première et deuxième broches de verrouillage mutuel (36, 46) agissent en douceur dans les canaux de verrouillage mutuel (24, 24').
