Abstract

The invention relates to 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. In that case fixed contacts are arranged in several horizontal planes around a rotatable switching shaft and on an insulating-material frame and have upper and lower contact fingers that can be pressed apart and with which electrical connection can be made by an electrically conductive rail as movable switching contact.
