Patent ID: 8030583

Claim:
A switching arrangement with two operational settings for switching over a winding during transformer operation, wherein during the switching-over a transient current commutates from one current path to another current path, wherein at least one horizontal plane is provided for each phase to be switched, wherein in each horizontal plane fixed contacts are arranged around a centrally and vertical rotatable switching shaft and on a common insulating-material frame and wherein selectable electrical connection with the fixed contacts in each plane can be made by at least one respective movable switching contact fastened on the switching shaft, characterized in that the movable switching contact is constructed as a curved horizontally extending rail of electrically conductive material and that the fixed contacts have upper and lower contact fingers that extend parallel to one another and that can be pressed apart against the force of upper and lower contact springs in such a manner that the movable switching contact can run in therebetween and produce an electrical contact.
