Abstract

The invention relates to a starter relay (19) for internal combustion engines, comprising a relay coil (27) and an armature (20), which interacts with a fork lever (21) by way of a driver (24) so as to toe-in a starter pinion, and comprising a contact bridge (34) which is to be actuated by the armature by way of a switch axis (32) and interacts with switch contacts (23a), wherein a coupling (33b) connects the switch axis and the armature such that they can be displaced with respect to each other to a limited extent. In order to ensure that welded contacts tear open and the neutral position of the fork lever is achieved when the relay is shut off, a pretensioned compression spring (26) is inserted between the armature (20) and the end of the fork lever (21).
