摘要： Disclosed is a device where a male contact body can be inserted into the female contact body along an insertion direction and the male contact body has a cavity which reaches through the male contact body; and a spreading element, which is inserted into the cavity and which has cross-sections that taper along the longitudinal axis of the spreading element in the securing direction, wherein the spreading element can be converted from a released position into a tightened position along the securing direction such that the male contact body is spread apart, thus generating a contact pressure between the female contact and the male contact body. In the process, the cavity reaches through the entire male contact body and thus forms two openings on the male contact body. The inner face of the male contact body has a first latching element, and the outer face of the spreading element has a second latching element, the first latching element latching with the second latching element when the spreading element reaches the tightened position so that the spreading element is secured in the tightened position.

摘要： The present invention relates to a switching device with at least one contact point and an arc blow device associated with the contact point, where the arc blow device comprises at least one blow magnet for generating a magnetic blow field, and where the blow field is of such nature that a switch arc developing when the contact point opens is blown out from the contact point. It is according to the invention provided that the blow field comprises a first magnetic field area and a second magnetic field area arranged adjacent to the first magnetic field area, where the magnetic field lines of the first magnetic field area are oriented in opposite direction to the magnetic field lines of the second magnetic field area, and where the blow field further comprises a transition area which connects the first magnetic field area and the second magnetic field area with each other, where the orientation of the magnetic field lines in the transition area, each starting out from the first magnetic field area and the second magnetic field area, aligns toward the contact point so that the switch arc within the transition area is in dependence of the direction of the current, starting out from the contact point, directed either into the first magnetic field area or into the second magnetic field area and there in both cases blown in the same direction away from the contact point.

摘要： The invention relates to a microswitch comprising a housing, a switching plunger arranged in displaced relationship with the center of said housing and projecting from said housing, contacts which are arranged on the housing side located opposite the switching plunger, and a contact bridge which is adapted to be transferred from a first to a second switching position through the switching plunger and a bistable spring, said switching plunger being provided with a cantilevered arm which projects on one side and on the projecting end of which a downholder is provided for positive opening of the contact bridge. In order to improve a microswitch of the type mentioned at the beginning in such a way that its overall size can be reduced still further and that a reliable positive opening operation will take place, the present invention is so conceived that, on the switching plunger side located opposite the cantilevered arm, a support projection is arranged, which acts on a resilient part of the spring in spaced relationship with the switching plunger, in such a way that, when the switching plunger is pressed down, a moment (M) will be applied via the support projection to the cantilevered arm of the switching plunger in the opening direction of the contact bridge.

摘要： A contractor (1) having at least two spaced-apart fixed contacts (2, 3) and an at least sectionwise electrically conductive, movable contact bridge (9) having at least two contact points (8) which are associated with the fixed contacts (2, 3). The contact bridge is adapted to be moved to a switched position by a switching force (B) and to a rest position by an opening force (V). The opening force (V) is produced by a pretensioning device (13). A particularly advantageous distribution of the opening force to the two contact points and a reliable switching operation is achieved in that one contact (2) is arranged between the other contact (3) and a point where the opening force (V) acts on the contact bridge (9).

摘要： The present invention refers to a switch device with at least one contact point, the contact point having a first contact and a second contact, the first and second contacts being spaced apart from one another in an open position and electrically contacting one another in a closed position, the contact point being assigned an arc blowout device for generating a magnetic blowing field, the blowout field being such that an arc produced when the contact point is opened is blown away from the contact point. In accordance with the invention, at least one of the two contacts is provided with a non-conductive cover on a non-contact-facing side which faces away from the other contact, which cover prevents a base point of the arc from crossing the non-contact-facing side.

摘要： The present invention relates to an electrical switching apparatus having at least one contact point, an arc-quenching device associated with the contact point, and an arc-blowing device to generate a magnetic blowout field. The arc-quenching device comprises a plurality of quenching elements, which are arranged distributed and spaced from each other in a first direction, wherein the quenching elements each comprise a permanent magnet. The arc arising when the contact point is opened is blown away from the contact point towards the quenching elements by the magnetic blowout field. The magnetic blowout field is at least partially generated or supported by the permanent magnets of the quenching elements. According to the invention, the permanent magnets of the quenching elements are offset with respect to each other in a second direction that is perpendicular to the first direction.

摘要： Disclosed is multipolar power contactor with an electromagnetic drive having an armature, and at least two movable contacts arranged next to one another and connected to the armature. The armature is movable from an open position, where the movable contacts and the fixed contacts are not in contact with one another, into a closed position where the movable contacts come into contact with the fixed contacts. Each movable contact and a corresponding fixed contact, is assigned an arc quenching device, and a plasma barrier having a first and a second barrier is provided between the two movable contacts, whereby one of the two barriers is connected to the armature and the other of the two barriers to a stationary part of the power contactor. The first and the second barrier overlap with one another at least partially in each position of the armature between the open and the closed positions.
