Abstract: The disclosure relates to a screw terminal for an electrical service device for connecting an electrical connecting conductor, which can be inserted through an insertion opening in the housing wall of the service switching device into the screw terminal. The screw terminal includes a terminal frame with a first transverse limb, which has a threaded hole for accommodating a clamping screw, and a clamping screw, which protrudes through the threaded hole into the terminal frame. The clamping frame, in its installed position in the housing of the service switching device, is guided displaceably parallel to the mid-axis of the clamping screw. The connecting conductor can be fixedly clamped in the terminal frame. That part of the terminal frame with which touching contact can be made in the installed position through the insertion opening from outside the device housing is covered by an insulating material.

Abstract: The invention relates to switching equipment comprising a housing, at least one contact point that has at least one fixed and one mobile contact part and an electromagnetic trip device, comprising a trip coil and a hammer armature. Said equipment is wherein the electromagnetic trip device comprises a snap body consisting of a material with magnetic shape memory properties, which interacts with the hammer armature. According to the invention, when a short-circuit occurs, the snap body is switched between two bi-stable positions by the influence of the magnetic field of the trip coil.

The tripping armature comprises at least two operatively connected tripping armature parts. The first tripping armature part is formed from a first material having a magnetic shape memory effect.

The tripping armature, both under the influence of the magnetic field of the tripping coil in the event of a short-circuit current and under the influence of an increase in temperature brought about by overcurrent, can be deformed and, as a result, the contact point can be caused to open.

Abstract: A measuring device for determining the oxygen content in gases is described. The measuring device is disposed between two magnets that are positioned at a distance from one another. The measuring device is equipped with a sensor that is held rotatably within a frame. The sensor has two parallelepipedic bodies that are both made hollow or solid and are connected to one another via a web-shaped structural element. The web-shaped structural element is fastened to the frame via at least one holding element, so that the sensor can be rotated about its center of gravity. The amount of rotation is dependent on the quantity of oxygen that is concentrated between the two magnets. A current can be conducted through a conductor track led on the surface of the sensor and generates a correspondingly high restoring force by which the sensor is brought into the position of rest again.

Abstract: A differential pressure sensor has a first and a second measuring chamber. Each measuring chamber is limited by a rigid carrier plate and a diaphragm plate, which is formed in the region of the measuring chamber as a pressure-sensitive measuring diaphragm. To design the differential pressure sensor to be resistant to overloading, the carrier plate is arranged between a first and a second diaphragm plate and has congruent concave depressions on opposite sides in the plane of the plate. The depressions are connected to one another by a central duct, penetrating the carrier plate perpendicularly to the plane of the plates. In the region of the measuring chambers, the diaphragm plates are formed congruently in relation to the depressions as pressure-sensitive measuring diaphragms. The measuring chambers are coupled to one another by a ram guided axially movably in the duct.
