Abstract

Improvements in a conductor protection switch, with electromagnetic, thermal and manual tripping, with a connection terminal arranged in the longitudinal direction of the side wall, which represents the switch retaining bottom, arranged adjacent to the lower area of the housing, with thermal trigger (bimetal), electromagnetic trigger, switching chamber with stationary contact piece and another connection terminal, the longitudinal axes of the triggers being located perpendicular to the clamping bottom, and with a retaining member arranged in the upper area of the housing, switching lever and mobile contact piece, constituted as a stationary supported rocker lever, which penetrates into the switching chamber for cooperation with the stationary contact piece, characterized in that a lowering chamber is arranged in the lower part of the switching chamber. electric arc, provided with extinguishing plates directed perpendicular to the f clamping wave, because the stationary contact part is attached by molding to the other connection terminal and for cooperation with the mobile contact part it protrudes perpendicularly above the free ends of the extinguishing plates at a distance, which guarantees the tilting movement of the moving contact piece and because a branch of the coil yoke, which represents the last extinguishing plate of the electromagnetic trigger electric arc chamber, at its free end is constituted as an appendix of electric arc rise, against the that the pound end of the movable contact piece moves when the contacts open.
