Abstract

L'invention concerne un interrupteur de circuit Selon l'invention, il comprend deux contacts séparables 2, 3, une chambre 1 d'augmentation de pression pouvant contenir un fluide d'extinction d'un arc dont la pression est élevée par un arc électrique établi entre les contacts, et une chambre 4 d'extinction de l'arc communiquant avec la chambre 1 pour amener et libérer le fluide dont la pression est augmentée dans la direction sensiblement perpendiculaire à l'arc établi entre les contacts. L'invention s'applique notamment aux interrupteurs à auto-extinction de l'arc.
