Abstract: A relay and control module combination wherein the control module has an essentially cuboid housing with a coupling side for plug connection to an auxiliary connection side of a cuboid relay housing. Mutually complementary plug connector elements, which can be connected mechanically and electrically, are provided in both the coupling side and in the auxiliary connection side, The plug connector elements allow mechanical and electrical coupling between the control module and the relay. In this way, a universal relay can be converted into a special relay having a specific function by plugging on the control module.

Abstract: The load section switch is connected between a pole post (4) and a main circuit (8) with a contact arrangement (14, 15, 36). Via a manually actuated switch arm (45), the contact arrangement can be locked in its closed condition, whereby the locking ensues via a switch pawl (39). This switch pawl (39), on the other hand, is coupled to the armature (28) of an electromagnet system (26, 27). In this way, the contact arrangement can be unlocked and the circuit can be interrupted via the electromagnet system given the occurrence of a malfunction condition. Given an accident or a short, the on-board network of a motor vehicle can be quickly disconnected from the current with this section switch in order to reduce the risk of fire or to prevent a discharge of the battery given some other malfunction condition.
