Abstract: A load-disconnecting switch has a permanent-magnetic holding circuit. A coil (5), upon excitation thereof, generates a magnetic flux that is opposite to the magnetic flux of the permanent magnet (9). The armature (6) is biassed to an open position by an armature spring (10), so that the armature spring (10), when a defined operational excitation is exceeded, detaches the armature (6) from the core (7) of the magnet system, allowing said armature to open and thereby disconnecting a switching contact (15) and a fixed contact (16). The load-disconnecting switch can be switched on again by means of a spring clip (12) acting on said armature (6).

Abstract: A switch relay with a switching status display is described, in which a display element is in operative connection with a switch contact of the switch relay and displays the switch positions in a clearly recognizable manner. The display element enlarges the display stroke so that contact movement is more readily visible. The principle is based on the elongation of a pointer of the flexing line of, for example, a constructed film hinge. As a result of the display element being constructed as a synthetic part low in mass, the contact dynamics are reduced by only a small extent.

Abstract: The battery section switch is switched between a terminal post and a main circuit using a contact arrangement. The contact arrangement can be locked in its closed position via a toggle spring device that acts directly on a free end of a contact spring. The toggle spring device is also coupled to the armature of an electromagnet system which, given excitation, releases the interlock and opens the contact arrangement. Given this battery section switch, the on-board network of a vehicle can be quickly switched current-free, given a collision or given a short-circuit, in order to reduce the risk of fire or in order to prevent a discharge of the battery given some other malfunction.
