Abstract

The relay has a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements (21, 22, 23, 24) and is mounted on the base by means of bearing strips, the bearing strips simultaneously serving as electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of the individual parts. This structure consequently permits non-problematic, cost-effective production of the individual parts and accurate assembly without the requirement of subsequent adjustment.
