Abstract
A contact arrangement for an electromagnetic switching apparatus having parallel offset contact bridges which are held in windows of a contact bridge carrier. These contact bridges are prevented from shifting transversely to the direction of force of a contact pressure spring pushing against a spring cup. The contact bridges are connectable to fixed contact parts. The spring cup is adapted to the offset of the contact bridges and has a separating rib for the contact bridges which extends between the two parallel contact bridges, so that mutual contact of the contact bridges with each other is impossible if diagonally opposite contact parts are welded together when the contacts are opened.
