摘要： The invention relates to a self-holding magnet with a spring (accumulator spring) and a first armature. The self-holding magnet is capable of holding the first magnet armature against the spring force in a lift position which is determined by a stop; the stop thus determines at least the remaining air gap of a working air gap. The magnetic circuit of the self-holding magnet comprises a magnetic shunt which has a particularly low reluctance of the same order of magnitude as the series reluctance of the remaining working air gap(s). The working air gap(s) and the shunt are magnetically connected in parallel in relation to the flow generated by a permanent magnet but are connected in series in relation to the flow generated by the (trigger) coil. The self-holding magnet additionally has at least one of the following three positive feedback devices: (1.) a resilient stop: the stop is capable of compressing to a certain extent and in the process is much more rigid than the accumulator spring but much less rigid than a solid stop made of iron would be, said stop preferably being 100 to 10,000 times more rigid than the accumulator spring; (2.) a shunt which is designed such that a movement of the armature results in a reduction of the reluctance of the shunt in that the self-holding magnet is designed as a reversal lifting magnet, the retaining force which can hold the accumulator spring in a biased manner being generated with as little characterizing influence as possible, and the shunt is designed as an armature/counter armature piece system, wherein energizing the coil in order to trigger the drive (counter excitation) then leads to a reduction of the flow in the air gap without a characterizing influence and to an increase of the flow through the armature/counter armature piece system, the force generated by the latter acting as much as possible in the same direction as the force of the accumulator spring; and (3.) a shunt which is designed such that a movement of the armature results in a reduction of the reluctance of the shunt in that the shunt is provided with a second armature (shunt armature) which is capable of closing the small air gap of the shunt up to a known (even smaller) remaining air gap. The force acting on the shunt armature is transmitted onto the armature of the self-holding magnet by means of a known device, for example a tappet, such that the force acts on said armature in the same direction as the force of the accumulator spring.

摘要： The invention relates to a relay for a defibrillator, comprising a support base (50) on which a coil (40) and a contacting unit (10) having a contact assembly are mounted. The contacting unit can be actuated by means of an armature (30) and at least one additional mechanical connecting link as a result of the electrical excitation of the coil. The contact assembly has contacts (11, 11') supported on contact carriers (12, 13, 14). The contacts can be connected to each other by activating the coil (40). In order to optimize the contacting, at least one connecting link is designed as a rotating lever (e.g. 22) coupled to the armature (30), which rotating lever is pivotably coupled to a contact carrier (e.g. 13), and another contact carrier (e.g. 14) is pivotably coupled to an additional rotating lever (e.g. 23) or directly to the armature (30), wherein both contact carriers (13, 14) having the contacts (11, 11') to be contacted are moved towards each other during contacting.

摘要： An electromagnetic switch is provided which is equipped with a built-in electronic control circuit working to control energization of an exciting coil. The electronic control circuit is disposed within a chamber defined by a magnetic plate to be separate from a contact chamber. In other words, the electronic control circuit is disposed between the magnetic plate and the exciting coil, thereby avoiding the adhesion of conductive dusts, as arising from the wear of contacts, to the surface of the electronic control circuit. This results in decreases in electric insulation and short-circuit of the electronic control circuit and also eliminates the need for additional special parts to electrically insulate and shield the electronic control circuit, thus permitting the electromagnetic switch to be reduced in size and produced at a decreased const.

摘要： Das Relais besitzt eine Blattfeder, die auf einem ebenen Auflageabschnitt (23) eines Jochschenkels (22) und/oder einem ebenen Auflageabschnitt (33) eines Ankers (30) befestigt ist und sich mit einem unbefestigten Federabschnitt über das freie Ende (24; 32) des Jochschenkels (22) bzw. des Ankers (30) hinweg erstreckt. Um bei Stößen eine plastische Deformierung der Blattfeder zu vermeiden, geht der ebene Auflageabschnitt (23; 33) jeweils in einen konvex gekrümmten Abrollabschnitt (25; 35) über, auf dem die Blattfeder bei einem Stoß abrollt, ohne sich bleibend zu verbiegen. Das Ende der Abrollbewegung wird zweckmäßigerweise durch einen Anschlag begrenzt. Auf diese Weise wird sichergestellt, daß das Relais auch bei stärkeren Stößen keine bleibende Veränderung seiner Kennwerte erleidet.

摘要： A direct current relay is disclosed, which is especially fit for railway type signalling systems. The said relay comprises a core (7) extending horizontally through a coil (8), an iron yoke (6) disposed above the core (7), and fixed to the core fore end, and extending along the coil (8) to the core rear end, an armature (11) pivotally mounted at the free end of yoke (6), in front of the corresponding rear end of core (7), and sets of moving and stationary contact members (C1, C2, C3, C4, C5) carried by moving and stationary, elastically flexible strips (24) which project in superposed and reciprocally spaced relationship from a contact carrier block fixed on the yoke (6). The free ends of the moving strips (24) are engaged with a vertically movable contact operator template (17) operatively connected with the armature (11) for movement of the moving strips, to cause the moving contact members (C1, C2) to be moved into or out of electrical contact with the stationary contact members (C3, C4, C5) when the relay is energized. The moving and stationary contact members are situated above the fore end of the yoke (6). Two counterweights (16) respectively arranged on either side of coil (8) are provided, which are operatively connected with the armature (11) for moving the same into rest position when the relay is de-energized.
