Zusammenfassung:An electrical switch includes a fixed contact member and a plurality of movable contact fingers that pivot into and out of engagement with the fixed contact member. The electrical switch also includes a fixed magnetic member and a plurality of U-shaped magnetic members housing the plurality of movable contact fingers. Upon occurrence of a fault condition, each of the plurality of U-shaped magnetic members is magnetically pulled towards the fixed magnetic member, without contacting the fixed magnetic member, such that each of the plurality of movable contact fingers is held in engagement with the fixed contact member.
