Abstract

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.
