Abstract (en)
[origin: US2005205394A1] The invention relates to a load changeover switch for a tap changer with two permanent main contact pairs for each phase to be switched, wherein the fixed contacts thereof are each time bridged over by a movable permanent main contact. The fixed permanent main contacts consist of a plurality of contact plates, which are articulated by means of contact springs, in the manner that the direction of deflection of the individual contact plates corresponds in each instance with the direction of impinging of the movable permanent main contact.
