ABSTRACT:
A contact bridge arrangement useful particularly in electromagnetic switchgear has a set of fixed contacts and a contact bridge which can be brought into active connection therewith. The contact bridge is movably guided in a window of a contact bridge carrier being spring loaded in the direction of the fixed contacts by a spring which is braced on a support part which is carried, in the active position, on parts fixed to the housing and which is elevated by a stop in the window of the contact bridge carrier. The support part is inserted between a spring cup and the stop in the window of the contact bridge carrier from the outside of the contact bridge assembly in a direction transverse to the direction of the spring loading.
