摘要： A protecting device has a disconnecting contact (13) connected to the load current line (2) and actuated by an electromagnetic system (9). A shunt circuit leads from the side of the disconnecting contact (13) opposite to the battery to an earth line (3), via a diode polarised in the blocking direction. The earth line (3) crosses or extends through the ferromagnetic circuit of the electromagnetic system (9). When the battery terminals are connected to reverse poles, a high short-circuit current flows through the diode (23) and induces an excitation in the ferromagnetic circuit (11, 12) of the magnetic system (9), lifting the armature (12) and opening the disconnecting contact (13).

摘要： A control component has a substantially square housing (11) with a coupling side (14) that can be connected by means of plugs to a matching connection side (25) of a square relay housing (21). Complementary plug-in connecting elements (26, 27) which can be mechanically and electrically interconnected are provided in the coupling side (14) and in the matching connection side (25) to electrically and mechanically couple the control component (10) to the relay (20). An universal relay may thus be transformed into a special relay with a particular special function by plugging the control component on the relay.

摘要： The load disconnecting switch is connected with a contact installation (14, 15, 36) between a pole terminal (4) and a main circuit (8). By means of a manually operated switch arm (45), the contact installation can be locked in the closed state, whereby the locking takes place by means of a ratchet (39). This ratchet (39) is, on the other hand, coupled with the armature (28) of an electro-magnetic system (26, 27). In this way, in the case of a dysfunction, the contact installation can be unlocked by means of the electro-magnetic system, and the circuit interrupted. With this disconnecting switch, the electrical system of a motor vehicle can, in the case of an accident or a short circuit, be connected quickly and without current, so as to reduce fire risk, or in the case of another dysfunction, to prevent discharging of the battery.
