ABSTRACT:
In a contact arrangement for high breaking capacity relays having a center contact spring movable between two cooperating fixed contact elements characterized by the contact spring having a contact member secured on each of the two opposite surfaces facing the fixed contact elements with one of the two contact members being of a larger size than the other contact member and the width of the contact spring to form a projection to which a flexible copper lead can be directly secured. As a result thereof, the switched current in a changeover contact can be conducted with low-loss across the center contact spring without an expensive center contact spring of a material which has a good conductivity being required.
