A sealed contactor for switching electric current has a switching assembly that includes a movable contact which selectively bridges a pair of stationary contacts to provide an electrical path therebetween. The moveable and stationary contacts are mounted to a body of electrically insulating material to form a unitized structure. A separate actuator assembly has an enclosure which contains an electrically operated driver with a linkage that extends into the switching assembly to alternately operate the moveable contact into engagement with and disengagement from the stationary contacts. The switching assembly is sealingly attached to the actuator assembly in an interlocking manner that prevents arcs produced between the contacts from escaping outside the electric current switching apparatus. Nevertheless, the switching assembly is capable of being easily removed and replaced as a single unit from the actuator assembly when repairing the contactor.
Contacteur isolé permettant de laisser passer ou d'arrêter un courant électrique, comprenant un contact mobile qui permet de relier volontairement deux contacts fixes pour laisser passer le courant. Le contact mobile et les contacts fixes sont logés dans un boîtier isolant, qui forme un ensemble. Un organe de commande distinct comprend un boîtier dans lequel se trouve un poussoir électrique muni d'une tige qui pénètre dans le contacteur et déplace longitudinalement le contact mobile pour ouvrir ou fermer le circuit. Même si le contacteur est relié par enclenchement et sous boîtier isolé à l'organe de commande afin d'empêcher les arcs produits entre les contacts de sortir du dispositif de commutation, on peut l'enlever facilement de l'organe de commande et le remplacer lors de réparations effectuées sur le contacteur.
