The present invention relates to a switch device for controlling electrical equipment. Such a switch device comprises a body piece (15), a sliding member (14) and contact surfaces controlled by the sliding member (14), means for latching the sliding member (14) into a closed/open position of the switch and for unlatching the sliding member (14) from said positions, a spring-arming plate (11) and switch actuator springs (10). The invention is implemented by making a slot (33) into the sliding member (14) that controls the second movable set of contact surfaces in the switch and adapting compatible interlock means (34) to the housing or body piece (15) of the switch, said interlock means serving to inhibit the movement of said sliding member (14) by virtue of partially entering the slot (33) made into the sliding member (14). Additionally, the spring-arming plate (11) is provided with a projection (32) capable of covering the slot (33) made into the sliding member (14) and thus preventing the interlock means (34) from inhibiting the movement of the sliding member (14) when the switch is being opened or closed. The switch device is also provided with another set of springs (31) for storing the mechanical energy required for a remote-controlled operation.

La présente invention concerne un interrupteur permettant de commander un appareillage électrique. Cet interrupteur comporte une pièce corps (15), un élément coulissant (14) et des surface de contact commandées par l'élément coulissant (14), un organe de verrouillage de l'élément coulissant (14) en position ouverte ou fermée de l'interrupteur, et de libération de cet élément coulissant (14) desdites positions, une platine (11) d'armement de ressort et des ressorts (10) d'actionnement d'interrupteur. On améliore l'invention en ménageant une fente (33) dans l'élément coulissant (14) pour qu'elle commande le second ensemble mobile de surfaces de contact dans l'interrupteur, et en adaptant au boîtier ou à la pièce corps (15) de l'interrupteur des moyens de liaison (34) compatibles. Ce moyen de liaison, servant à empêcher le mouvement dudit élément coulissant (14), est pour ce faire, partiellement introduit dans la fente (33) ménagée dans l'élément coulissant (14). En outre, la platine (11) d'armement de ressort est pourvue d'une saillie (32) capable de recouvrir la fente (33) ménagée dans l'élément coulissant (14) et, ainsi, éviter que l'organe de verrouillage (34) n'empêche le mouvement de l'élément coulissant (14) lors de l'ouverture ou de la fermeture de l'interrupteur. L'interrupteur est également pourvu d'un autre ensemble de ressorts (31) permettant de stocker l'énergie mécanique nécessaire à un fonctionnement commandé à distance.
