Abstract
A contact arrangement for a relay having a high breaking current capacity. A contact spring is split in fork-like fashion so as to form two fork ends at its free end. The contact spring is opposite two cooperating contact elements in the form of a double contact or two contacts to be bridged. The two fork ends of the contact spring are directly connected to one another via a welded on contact strip. A stranded conductor is welded directly to a freely accessible center portion of the contact strip between the two fork ends. Thus, the two contacting locations of the contact spring are connected to one another or to a power terminal in a low-loss fashion without employing an expensive central contact spring having good conductivity. Rather, a spring steel having a relatively poor conductivity may be employed.
