Abstract: A housing for an electrical device comprises a housing bottom, a fastening element, and an unlocking element and is closeable by a housing cover. The housing bottom includes an elastically deformable connecting section to connect the housing to a machine, a technical system, or a building wall. The fastening element is disposed on an outer face of the connecting section and is connectable in a form-fitting and/or friction-fitting manner to a corresponding retaining element of the machine, the technical system, or the building wall. The unlocking element is disposed on an inner face of the connecting section and is operatively connected to the fastening element. The unlocking element is user actuatable only from an inside of the housing when the housing is open in order to release the form-fitting and/or friction-fitting connection of the fastening element to the retaining element of the machine, the technical system, or the building wall.

Abstract: A safety switching device for switching on and safely switching off an electrical load, comprising a failsafe evaluation/control unit, an output terminal for providing a potential, a switching element having a first working contact, wherein the potential is connectable to the output terminal via the first working contact, and an input terminal for receiving an input signal for operating the switching element via the evaluation/control unit. Additionally, the safety switching device comprises a separator having a connecting piece, a drive element and a separating element. The drive element is configured to mechanically move the separating element from a first position into a second position and the connecting piece and the first working contact electrically connect in series with one another the potential to the output terminal. Further, in the second position the separating element irreversibly separates the connecting piece into two pieces.

Abstract: An emergency command device comprises: two safety inputs connectable to a control/evaluating unit to receive an input voltage; two safety outputs connectable to the control/evaluating unit; two electrical switching paths respectively extending between the two safety inputs and the two safety outputs; an emergency actuating unit comprising: a manually triggerable actuating element, a background element, and two switches connected to the actuating element and respectively disposed in the two electrical switching paths; a light emitting unit comprising red LEDs to backlight the actuating element and yellow LEDs to backlight the background element; a voltage detector detect an electrical output voltage at one of the two safety outputs; and a flashing circuit arrangement coupled to activate flashing of the yellow LEDs and/or the red LEDs in response to detection by the voltage detector of a drop in the output voltage below a preset or presettable threshold value.
