Abstract (en)

Electric switch has contact bridge (24) with housing (70) used for supporting two contact blades (56, 58). One blade has lateral zone for arc transfer situated to larger distance relative to median plane than contact zone of blade. Switch also includes spark suppressor (40) linked to fixed blade (20, 22). When contact bridge is in its opened position, shortest distance between spark suppressor and contact bridge is measured between zone for arc transfer and corresponding zone on lateral parts of suppressor, and this distance is smaller than shortest distance between contact bridge and fixed blade.

Abstract (fr)

Un interrupteur comporte un organe de contact fixe (20, 22) à couteau et un organe de contact mobile (24) à pince comportant deux lames de contact (56, 58), munies chacune d'une zone de contact (60, 62) et d'une zone latérale de transfert de l'arc (64, 66). Un pare étincelle (40) métallique solidaire de l'organe de contact fixe (20, 22) et en contact électrique avec celui-ci, a un rebord supérieur (48) incurvé avec une partie médiane (50) située à faible distance de l'organe de contact fixe (20, 22) et deux parties latérales (52, 54) située à plus grande distance du plan médian et du contact fixe. Lorsque l'organe de contact mobile (24) est dans sa position d'ouverture, la distance la plus courte entre le pare étincelle (40) et l'organe de contact mobile (24) est mesurée entre la zone de transfert de l'arc (64, 66) et une zone correspondante de ladite partie latérale (52, 54) du rebord supérieur de la plaque, et cette distance est plus faible que la plus courte distance entre l'organe de contact mobile (24) et l'organe de contact fixe (20, 22). <IMAGE>
