A changeover arrangement for load selector switches of tapped transformers having a plurality of fixed tap contacts which are arranged in a circle and having two switching contacts which can roll on said tap contacts, change over the load output line and, in the quiescent state, both rest on one tap contact. Each switching contact is permanently conductively connected to in each case one further series contact, the series contact being constructed as a contact roller which can roll directly on a circular output rail, is located approximately on the same axis as the switching contact allocated to it and is connected thereto via a flexible shaft which is constructed as an electrical conductor. In this case, during the changeover process, in each case one contact roller can be lifted off the output rail by means of a stop lever. |
