Abstract: A modular safety switching device is set up such that various signaling devices in a set of possible connectable signaling devices can be connected. In this case, a typical combination of inputs and outputs that are used is provided for each signaling device. The nature of the connection of the signaling device is unique for each signaling device within the set, by which the safety switching device can identify during startup, on the basis of the electrical connections that are made, which type of signaling device is connected and what function is required for identical signaling devices. The safety switching device automatically changes itself to the required operating mode in accordance with this association.

Abstract: A toploaded balance in accordance with the principle of the electromagnetic compensation of force with a divided upper guide rod (3, 3') and a divided lower guide rod (4, 4') which together as a parallel guide connect a load receiver (2) to a system carrier (1) fixed to the housing, which system carrier (1), load receiver (2) and guide rods (3, 3', 4, 4') form a one-piece base, with a translation lever (5) rotatably mounted by two flexible articulations (7) on the system carrier (1), with a coupling element (12) connected by flexible articulations on the one hand to the load receiver (2) and on the other hand to the short lever arm of the translation lever (5), with a magnet build, as viewed from above, into the free space between the parts of the guide rods (3, 3', 4, 4') and their extensions on the system-carrier side and with a coil fastened on the longer lever arm of the translation lever (5) and extending into the air gap of the magnet, the translation lever (5), the two flexible articulations (7) for mo
