Abstract

Dispositif d'ouverture rapide des contacts d'un interrupteur sous l'effet de la répulsion électrodynamique. Le pont de contact mobile est relié au porte-contact par un dispositif de liaison amovible, associé à un organe élastique qui assure la pression des contacts; une course déterminée du dispositif de liaison effectuant une compression supplémentaire de l'organe élastique, provoque l'interruption de la liaison. Ce dispositif est avantageusement utilisé dans les interrupteurs manuels ou discontacteurs limitant les courants de court-circuit.
