Es ist die Aufgabe der vorliegenden Offenbarung, eine weitere effiziente Schaltkontaktanordnung bereitzustellen, welche insbesondere eine Herstellung der Schaltkontaktanordnung mit einer vorteilhaft reduzierten Anzahl von Fertigungsschritten ermöglicht.It is the object of the present disclosure to provide a further efficient switch contact arrangement which, in particular, enables the switch contact arrangement to be produced with an advantageously reduced number of production steps.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche, der Beschreibung sowie der beiliegenden Figuren.This object is achieved by the features of the independent claims. Advantageous embodiments are the subject matter of the dependent claims, the description and the accompanying figures.

Die vorliegende Offenbarung basiert auf der Erkenntnis, dass die obige Aufgabe durch eine Schaltkontaktanordnung realisiert werden kann, welche einen ersten Kontaktträger, einen zweiten Kontaktträger und eine Kontaktfeder umfasst, wobei der erste Kontaktträger unterhalb der Kontaktfeder und der zweite Kontaktträger oberhalb der Kontaktfeder angeordnet ist. Ferner ist die Kontaktfeder ausgebildet, mit dem ersten Kontaktträger eine elektrische Verbindung an einem ersten Kontaktpol herzustellen und mit dem zweiten Kontaktträger eine elektrische Verbindung an einem zweiten Kontaktpol herzustellen, wobei der erste Kontaktpol seitlich versetzt zu dem zweiten Kontaktpol angeordnet ist und Kontaktstecker zum elektrischen Verbinden mit den Kontaktträgern und der Kontaktfeder seitlich nebeneinander angeordnet sind.The present disclosure is based on the knowledge that the above object can be achieved by a switching contact arrangement which comprises a first contact carrier, a second contact carrier and a contact spring, the first contact carrier being arranged below the contact spring and the second contact carrier being arranged above the contact spring. Furthermore, the contact spring is designed to establish an electrical connection to a first contact pole with the first contact carrier and to establish an electrical connection to a second contact pole with the second contact carrier, the first contact pole being arranged laterally offset from the second contact pole and contact plug for electrical connection with the contact carriers and the contact spring are arranged side by side.

Gemäß einem ersten Aspekt betrifft die Offenbarung eine Schaltkontaktanordnung für ein Relais. Die Schaltkontaktanordnung umfasst einen ersten Kontaktträger, welcher einen ersten Kontaktstecker und einen ersten Kontaktpol umfasst, wobei der erste Kontaktpol in einer ersten Schaltebene angeordnet ist und der erste Kontaktstecker einteilig mit dem ersten Kontaktträger gebildet ist und wobei der erste Kontaktträger über den ersten Kontaktstecker mit einem elektrischen Signal beaufschlagbar ist. Ferner umfasst die Schaltkontaktanordnung einen zweiten Kontaktträger, welcher einen zweiten Kontaktstecker und einen zweiten Kontaktpol umfasst, wobei der zweite Kontaktpol in einer zweiten Schaltebene angeordnet ist, welche parallel beabstandet von der ersten Schaltebene angeordnet ist, und wobei der zweite Kontaktträger über den zweiten Kontaktstecker mit einem weiteren elektrischen Signal beaufschlagbar ist.According to a first aspect, the disclosure relates to a switching contact arrangement for a relay. The switching contact arrangement comprises a first contact carrier which comprises a first contact plug and a first contact pole, the first contact pole being arranged in a first switching plane and the first contact plug being formed in one piece with the first contact carrier and the first contact carrier being connected to an electrical one via the first contact plug Signal can be acted upon. Furthermore, the switching contact arrangement comprises a second contact carrier, which comprises a second contact plug and a second contact pole, wherein the second contact pole is arranged in a second switching plane, which is arranged parallel spaced from the first switching plane, and wherein the second contact carrier via the second contact plug with a further electrical signal can be applied.

Weiterhin umfasst die Schaltkontaktanordnung eine Kontaktfeder, welche einen dritten Kontaktträger und einen dritten Kontaktstecker aufweist, wobei die Kontaktfeder zwischen der ersten Schaltebene und der zweiten Schaltebene angeordnet ist, und wobei der dritte Kontaktträger über den dritten Kontaktstecker mit einem dritten elektrischen Signal beaufschlagbar ist, und wobei die Kontaktfeder einen dritten Kontaktpol, welcher dem ersten Kontaktpol zugewandt ist und einen vierten Kontaktpol, welcher dem zweiten Kontaktpol zugewandt ist, aufweist, und wobei der dritte Kontaktpol seitlich versetzt neben dem vierten Kontaktpol angeordnet ist.Furthermore, the switching contact arrangement comprises a contact spring which has a third contact carrier and a third contact plug, the contact spring being arranged between the first switching level and the second switching level, and wherein the third contact carrier can be acted upon by a third electrical signal via the third contact plug, and wherein the contact spring has a third contact pole facing the first contact pole and a fourth contact pole facing the second contact pole, and wherein the third contact pole is arranged laterally offset next to the fourth contact pole.

Die Schaltkontaktanordnung kann insbesondere geeignet sein, in ein Relais mit einer reduzierten Baubreite von 3 mm eingesetzt zu werden. Vorteilhafterweise kann die Schaltkontaktanordnung zur Verwendung in einem 3 mm-Relais kosteneffizienter als eine Schaltkontaktanordnung zur Verwendung in einem 5 mm-Relais hergestellt werden. Zusätzlich kann eine Montage der Schaltkontaktanordnung in dem Relais vereinfacht sein.The switching contact arrangement can in particular be suitable for being used in a relay with a reduced overall width of 3 mm. The switch contact arrangement for use in a 3 mm relay can advantageously be produced in a more cost-effective manner than a switch contact arrangement for use in a 5 mm relay. In addition, assembly of the switch contact arrangement in the relay can be simplified.

Die Bestandteile der Schaltkontaktanordnung sind in der ersten Schaltebene oder in der zweiten Schaltebene angeordnet, wobei die Kontaktfeder und der zweite Kontaktträger jeweils einen Übergangsbereich aufweisen können, welcher eine Verbindung zwischen der ersten Schaltebene und der zweiten Schaltebene realisiert. Entsprechend kann eine Anzahl von Biegevorgängen, welche zur Herstellung der Schaltkontaktanordnung notwendig sein kann, vorteilhaft reduziert sein.The components of the switching contact arrangement are arranged in the first switching level or in the second switching level, wherein the contact spring and the second contact carrier can each have a transition area which realizes a connection between the first switching level and the second switching level. Correspondingly, a number of bending processes, which may be necessary for producing the switch contact arrangement, can advantageously be reduced.

Zur Herstellung der Schaltkontaktanordnung können vorteilhafterweise planare Halbzeuge eingesetzt werden, welche insbesondere durch Stanzen, Nieten und Biegen zu der Schaltkontaktanordnung geformt werden. Durch die planare Form der Kontaktträger und der Kontaktfeder kann die Schaltanordnung mittels eines kombinierten Stanz-biegeverfahrensschritt und einem Nietverfahrensschritt hergestellt sein.To produce the switch contact arrangement, planar semi-finished products can advantageously be used, which are formed into the switch contact arrangement in particular by punching, riveting and bending. Due to the planar shape of the contact carriers and of the contact spring, the switching arrangement can be produced by means of a combined stamping and bending process step and a riveting process step.

In einer Ausführungsform umfasst die Kontaktfeder ein Federelement, welches ausgebildet ist, bei einer Auslenkung der Kontaktfeder von einer Ruhelage eine Rückstellkraft zu erzeugen, welche die Kontaktfeder in die Ruhelage zurücktreibt.In one embodiment, the contact spring comprises a spring element which is designed to generate a restoring force when the contact spring is deflected from a rest position, which restoring force drives the contact spring back into the rest position.

Dadurch wird der Vorteil erreicht, dass der dritte Kontaktträger federnd an dem zweiten Kontaktträger oder an dem ersten Kontaktträger gelagert sein kann, wobei jeweils der zweite Kontaktpol auf dem vierten Kontaktpol aufliegt oder der erste Kontaktpol auf dem dritten Kontaktpol aufliegt. Ferner kann in einer Ruhelage der Kontaktfeder der erste Kontaktpol von dem dritten Kontaktpol beabstandet sein und der zweite Kontaktpol von dem vierten Kontaktpol beabstandet sein. Entsprechend kann die Schaltkontaktanordnung drei Schaltzustände aufweisen. In einem ersten Schaltzustand können die drei Kontaktträger voneinander elektrisch getrennt sein, in einem zweiten Schaltzustand können der erste Kontaktträger und der dritte Kontaktträger elektrisch miteinander verbunden sein und/oder in einem dritten Schaltzustand können der zweite Kontaktträger und der dritte Kontaktträger elektrisch miteinander verbunden sein. Vorzugsweise ist der dritte Kontaktträger in einer Ruhelage der Kontaktfeder mit dem ersten Kontaktträger oder mit dem zweiten Kontaktträger elektrisch verbunden, in dem die jeweiligen Kontaktpole aufeinander aufliegen. Eine Auslenkung der Kontaktfeder bewirkt eine Trennung des elektrischen Kontakts zwischen den zuvor aufeinanderliegenden Kontaktpolen und das jeweils andere Kontaktpolpaar wird elektrisch miteinander verbunden.This has the advantage that the third contact carrier can be resiliently mounted on the second contact carrier or on the first contact carrier, the second contact pole resting on the fourth contact pole or the first contact pole resting on the third contact pole. Furthermore, in a rest position of the contact spring, the first contact pole can be spaced apart from the third contact pole and the second contact pole can be spaced apart from the fourth contact pole. The switching contact arrangement can accordingly have three switching states. In a first switching state, the three contact carriers can be electrically isolated from one another, in a second switching state the first contact carrier and the third contact carrier can be electrically connected to one another and / or in a third switching state the second contact carrier and the third contact carrier can be electrically connected to one another. In a rest position of the contact spring, the third contact carrier is preferably electrically connected to the first contact carrier or to the second contact carrier, in which the respective contact poles rest on one another. A deflection of the contact spring causes a separation of the electrical contact between the contact poles previously lying on top of one another and the respective other contact pole pair is electrically connected to one another.

In einer Ausführungsform sind der erste Kontaktträger und der zweite Kontaktträger aus einem ersten Blechplatinenstück gebildet und die Kontaktfeder ist aus einem zweiten Blechplatinenstück gebildet.In one embodiment, the first contact carrier and the second contact carrier are formed from a first sheet metal piece and the contact spring is formed from a second sheet metal piece.

Die Schaltkontaktanordnung weist bei einer Sicht entlang einer Flächennormale der ersten Schaltebene und/oder der zweiten Schaltebene überlappende Flächen zwischen dem ersten Kontaktträger und dem dritten Kontaktträger und/oder dem zweiten Kontaktträger und dem dritten Kontaktträger, insbesondere im Bereich der Kontaktpole auf. Entsprechend können der erste Kontaktträger und der zweite Kontaktträger, welche keine überlappenden Flächen aufweisen aus dem gleichen Blechplatinenstück hergestellt werden. Die Kontaktfeder mit dem dritten Kontaktträger kann aus einem weiteren Blechplatinenstück hergestellt sein und durch ein Einschieben parallel zu der ersten Schaltebene und/oder der zweiten Schaltebene zwischen dem ersten Kontaktträger und dem zweiten Kontaktträger angeordnet sein.When viewed along a surface normal of the first switching plane and / or the second switching plane, the switching contact arrangement has overlapping surfaces between the first contact carrier and the third contact carrier and / or the second contact carrier and the third contact carrier, in particular in the area of the contact poles. Correspondingly, the first contact carrier and the second contact carrier, which do not have any overlapping surfaces, can be produced from the same piece of sheet metal blank. The contact spring with the third contact carrier can be made from a further piece of sheet metal blank and can be pushed in parallel to the first Switching level and / or the second switching level can be arranged between the first contact carrier and the second contact carrier.

In einer Ausführungsform sind der erste Kontaktstecker, der zweite Kontaktstecker und der dritte Kontaktstecker aus dem ersten Blechplatinenstück gebildet. Insbesondere können die Kontaktstecker und der erste Kontaktträger und der zweite Kontaktträger aus dem gleichen Blechplatinenstück hergestellt sein, um eine effiziente Herstellung der Schaltkontaktanordnung mit einer reduzierten Anzahl an Herstellungsschritten zu realisieren.In one embodiment, the first contact plug, the second contact plug and the third contact plug are formed from the first sheet metal piece. In particular, the contact plugs and the first contact carrier and the second contact carrier can be made from the same sheet metal piece in order to realize an efficient production of the switching contact arrangement with a reduced number of production steps.

Erfindungsgemäß sind der erste Kontaktstecker, der zweite Kontaktstecker und der dritte Kontaktstecker in der ersten Schaltebene angeordnet. Dadurch wird der Vorteil erreicht, dass die Kontaktstecker in einer Reihe angeordnet sein können, welche senkrecht zu einer Baubreite eines Relais angeordnet ist, sodass die Kontaktstecker innerhalb der Baubreite des Relais angeordnet sein können.According to the invention, the first contact plug, the second contact plug and the third contact plug are arranged in the first switching level. This achieves the advantage that the contact plugs can be arranged in a row which is arranged perpendicular to an overall width of a relay, so that the contact plugs can be arranged within the overall width of the relay.

In einer Ausführungsform weist der dritte Kontaktstecker zumindest eine Verbindungsstelle auf, welche ausgebildet ist, den dritten Kontaktträger mit dem dritten Kontaktstecker elektrisch zu verbinden und mechanisch zu fixieren.In one embodiment, the third contact plug has at least one connection point which is designed to electrically connect the third contact carrier to the third contact plug and to fix it mechanically.

Dadurch wird der Vorteil erreicht, dass die Kontaktfeder zweiteilig aus zwei unterschiedlichen Blechplatinenstücken zusammengesetzt sein kann. Insbesondere können der dritte Kontaktstecker und der dritte Kontaktträger aus jeweils separaten Blechplatinenstücken hergestellt, insbesondere gestanzt und gebogen sein, um anschließend an der Kontaktstelle zusammengefügt zu werden. Der dritte Kontaktträger kann insbesondere mit dem dritten Kontaktträger vernietet, verpresst, verschweißt und/oder verlötet werden. Ferner kann der dritte Kontaktträger mittels einer Steckverbindung mit dem dritten Kontaktstecker verbunden sein.This has the advantage that the contact spring can be assembled in two parts from two different sheet metal pieces. In particular, the third contact plug and the third contact carrier can each be produced from separate sheet metal pieces, in particular punched and bent, in order to then be joined together at the contact point. The third contact carrier can in particular be riveted, pressed, welded and / or soldered to the third contact carrier. Furthermore, the third contact carrier can be connected to the third contact plug by means of a plug connection.

In einer Ausführungsform ist der erste Kontaktträger in der ersten Schaltebene L-förmig ausgebildet und der zweite Kontaktträger ist abgewinkelt ausgebildet, um den Abstand zwischen dem zweiten Kontaktpol in der zweiten Schaltebene und dem zweiten Kontaktstecker in der ersten Schaltebene zu überwinden.In one embodiment, the first contact carrier is L-shaped in the first switching plane and the second contact carrier is angled in order to overcome the distance between the second contact pole in the second switching plane and the second contact plug in the first switching plane.

Dadurch wird der Vorteil erreicht, dass zwischen dem ersten Kontaktträger und dem zweiten Kontaktträger ein Zwischenraum zum Einsetzen, insbesondere Einschieben der Kontaktfeder und/oder des dritten Kontaktträgers geschaffen ist. In dem Bereich der Kontaktpole ergibt sich daher von der ersten Schaltebene aus gesehen die Anordnung erster Kontaktträger, dritter Kontaktträger und abschließend aufliegend der zweite Kontaktträger. Der zweite Kontaktträger kann insbesondere z-förmig und/oder rechtwinklig gebogen sein, um einen Abstand zu dem zweiten Kontaktstecker zu überwinden.This achieves the advantage that an intermediate space is created between the first contact carrier and the second contact carrier for inserting, in particular pushing in, the contact spring and / or the third contact carrier. In the area of Contact poles, viewed from the first switching level, therefore result in the arrangement of the first contact carrier, third contact carrier and finally the second contact carrier. The second contact carrier can in particular be bent in a z-shape and / or at right angles in order to overcome a distance from the second contact plug.

In einer Ausführungsform ist das Federelement zwischen dem dritten Kontaktträger und dem dritten Kontaktstecker angeordnet und z-förmig geformt, um einen Abstand zwischen der ersten Schaltebene und der zweiten Schaltebene zu überbrücken.In one embodiment, the spring element is arranged between the third contact carrier and the third contact plug and is Z-shaped in order to bridge a distance between the first switching plane and the second switching plane.

In einer Ausführungsform sind die jeweiligen Kontaktpole auf den jeweiligen Kontaktträger genietet und/oder geschweißt. Ferner können die Kontaktpole auch auf die Kontaktträger gelötet sein. In einer Ausführungsform können die Kontaktpole durch Umformen des jeweiligen Kontaktträgers gebildet sind. Die Kontaktpole können insbesondere eine gewölbte Form aufweisen. Für eine Nietverbindung zwischen einem Kontaktpol und einem Kontaktträger kann ein Durchbruch in dem Kontaktträger vorgesehen sein. Die Kontaktpole können gegenüber den Kontaktträgern widerstandsfähiger gegenüber Kontaktabbrand ausgebildet sein, um eine mögliche Anzahl von Schaltvorgängen mit anliegen einer elektrischen Last zwischen den Kontaktpolen zu erhöhen.In one embodiment, the respective contact poles are riveted and / or welded onto the respective contact carrier. Furthermore, the contact poles can also be soldered onto the contact carriers. In one embodiment, the contact poles can be formed by reshaping the respective contact carrier. The contact poles can in particular have a curved shape. For a riveted connection between a contact pole and a contact carrier, an opening can be provided in the contact carrier. The contact poles can be designed to be more resistant to contact erosion than the contact carriers in order to increase a possible number of switching operations with an electrical load applied between the contact poles.

In einer Ausführungsform umfasst die Schaltkontaktanordnung einen Kopplungsarm, welcher mit einem Anker eines Magnetsystems koppelbar ist, wobei der Kopplungsarm ausgebildet ist, mit einer mittels des Ankers auf den Kopplungsarm einwirkenden Kraft, eine Translation der Kontaktfeder senkrecht zu einer Längsachse des Ankers zu bewirken, um die Kontaktfeder mit einem der Kontaktträger elektrisch leitend zu verbinden.In one embodiment, the switching contact arrangement comprises a coupling arm which can be coupled to an armature of a magnet system, the coupling arm being designed to bring about a translation of the contact spring perpendicular to a longitudinal axis of the armature with a force acting on the coupling arm by means of the armature To connect contact spring with one of the contact carriers in an electrically conductive manner.

Dadurch wird der Vorteil erreicht, dass die Kontaktfeder abwechselnd den ersten Kontaktpol mit dem dritten Kontaktpol und den zweiten Kontaktpol mit dem vierten Kontaktpol elektrisch leitend verbinden kann. Der Kopplungsarm kann insbesondere einteilig mit der Kontaktfeder gebildet sein. Ferner können seitlich neben dem dritten Kontaktpol und/oder dem vierten Kontaktpol der Kopplungsarm und/oder ein weiterer Kopplungsarm angeformt sein, wobei der Anker auf bei Kopplungsarme gleichzeitig einwirkt, um eine Torsion der Kontaktfeder um eine Längsachse der Kontaktfeder zu unterbinden.This has the advantage that the contact spring can alternately connect the first contact pole to the third contact pole and the second contact pole to the fourth contact pole in an electrically conductive manner. The coupling arm can in particular be formed in one piece with the contact spring. Furthermore, the coupling arm and / or a further coupling arm can be formed laterally next to the third contact pole and / or the fourth contact pole, the armature acting simultaneously on the coupling arms to prevent torsion of the contact spring about a longitudinal axis of the contact spring.

In einer Ausführungsform ist der Kopplungsarm seitlich neben dem dritten Kontaktträger angeordnet und weist einen Kopplungsbereich auf, welcher ausgebildet ist, einen Hebelarm des Magnetsystems zumindest teilweise formschlüssig aufzunehmen.In one embodiment, the coupling arm is arranged laterally next to the third contact carrier and has a coupling area which is designed to receive a lever arm of the magnet system at least partially in a form-fitting manner.

Dadurch wird der Vorteil erreicht, dass der Kopplungsarm mit dem Hebelarm mechanisch fest mit dem Magnetsystem gekoppelt werden kann. Insbesondere kann dadurch eine effiziente Kraftübertragung von dem Magnetsystem auf die Kontaktfeder realisiert werden. Der Formschluss zwischen dem Hebelarm und dem Kopplungsarm kann beispielsweise durch Eingreifen eines zylindrischen Vorsprung des Hebelarms, welcher in eine Öffnung des Kopplungsarms eingreift realisiert sein. Auf der Mantelfläche des zylindrischen Vorsprungs kann ferner ein Rastverbinder in Form einer Rastnase und/oder einer Rastvertiefung ausgebildet sein, in welche der Kopplungsarm eingreift respektive einrastet. Die Verbindung zwischen Kopplungsarm und dem Hebelarm kann insbesondere spielfrei ausgebildet sein, um eine Translation des Hebelarms möglichst verlustarm in eine Translation des Kopplungsarms und entsprechend der Kontaktfeder umzusetzen. Mit der Formschlussverbindung kann der Kopplungsarm sowohl in Richtung der ersten Schaltebene als auch entgegengesetzt in Richtung der zweiten Schaltebene bewegt werden.This achieves the advantage that the coupling arm with the lever arm can be mechanically firmly coupled to the magnet system. In particular, an efficient transmission of force from the magnet system to the contact spring can thereby be achieved. The form fit between the lever arm and the coupling arm can be implemented, for example, by engaging a cylindrical projection of the lever arm which engages in an opening in the coupling arm. A latching connector in the form of a latching lug and / or a latching recess, into which the coupling arm engages or latches, can also be formed on the outer surface of the cylindrical projection. The connection between the coupling arm and the lever arm can in particular be designed without play in order to convert a translation of the lever arm into a translation of the coupling arm and corresponding to the contact spring with as little loss as possible. With the form-fit connection, the coupling arm can be moved both in the direction of the first switching level and in the opposite direction in the direction of the second switching level.

In einer Ausführungsform ist die Kontaktfeder in der Ruhelage von dem ersten Kontaktträger und/oder dem zweiten Kontaktträger elektrisch isoliert. Dadurch kann der Vorteil erreicht werden, dass mit einer Auslenkung der Kontaktfeder ein Kontaktpolpaar, beispielsweise der zweite Kontaktpol und der vierte Kontaktpol elektrisch getrennt und ein weiteres Kontaktpolpaar; beispielsweise der erste Kontaktpol und der dritte Kontaktpol elektrisch verbunden werden kann.In one embodiment, the contact spring is electrically isolated from the first contact carrier and / or the second contact carrier in the rest position. In this way, the advantage can be achieved that, with a deflection of the contact spring, a contact pole pair, for example the second contact pole and the fourth contact pole, are electrically separated and a further contact pole pair; for example, the first contact pole and the third contact pole can be electrically connected.

In einer Ausführungsform weisen der erste Kontaktträger, der zweite Kontaktträger und/oder der dritte Kontaktträger Öffnungen zur Aufnahme von Stiften eines Relaisgehäuses auf, um die Schaltkontaktanordnung in einem Relaisgehäuse zu fixieren.In one embodiment, the first contact carrier, the second contact carrier and / or the third contact carrier have openings for receiving pins of a relay housing in order to fix the switching contact arrangement in a relay housing.

Dadurch kann der Vorteil erreicht werden, dass das Relaisgehäuse effizient in dem Relaisgehäuse gehalten werden kann. Insbesondere der erste Kontaktträger und der zweite Kontaktträger können mechanisch fest mit dem Relaisgehäuse verbunden sein. Ferner kann ein Teil der Kontaktfeder, welcher beispielsweise die Verbindungsstelle und den dritten Kontaktstecker umfasst, fest mittels einer mechanischen Verbindung zwischen den Öffnungen und den Stiften des Relaisgehäuses in dem Relaisgehäuse fest verankert werden. Das Federelement und der dritte Kontaktträger können gegenüber dem Relaisgehäuse beweglich angeordnet sein.Thereby, the advantage can be obtained that the relay housing can be efficiently held in the relay housing. In particular, the first contact carrier and the second contact carrier can be mechanically firmly connected to the relay housing. Furthermore, a part of the contact spring, which comprises, for example, the connection point and the third contact plug, can be firmly anchored in the relay housing by means of a mechanical connection between the openings and the pins of the relay housing. The spring element and the third contact carrier can be arranged to be movable relative to the relay housing.

Insbesondere kann der zweite Kontaktträger, welcher Abschnitte in der ersten Schaltebene und weitere Abschnitte in der zweiten Schaltebene aufweist, in der jeweiligen Schaltebene mittels Verbindungen zwischen Stiften des Relaisgehäuses und entsprechenden Öffnungen in den Abschnitten des zweiten Kontaktträgers fixiert sein. Ferner kann die Schaltkontaktanordnung mittels Klemmverbindungen an den Kanten der Kontaktträger und/oder mittels stoffschlüssiger Verbindungen, insbesondere Klebeverbindung in dem Relaisgehäuse befestigt sein.In particular, the second contact carrier, which has sections in the first switching plane and further sections in the second switching plane, can be fixed in the respective switching plane by means of connections between pins of the relay housing and corresponding openings in the sections of the second contact carrier. Furthermore, the switching contact arrangement can be fastened to the edges of the contact carrier by means of clamping connections and / or by means of material connections, in particular adhesive connections, in the relay housing.

In einer Ausführungsform umfasst die Schaltkontaktanordnung einen ersten Versatzabschnitt, welcher an dem ersten Kontaktstecker angeordnet und ausgebildet ist, den ersten Kontaktstecker entlang einer Flächennormale der ersten Schaltebene um einen vorbestimmten Abstand von der ersten Schaltebene versetzt anzuordnen. Der erste Versatzabschnitt ist insbesondere einteilig mit dem ersten Kontaktstecker und/oder dem ersten Kontaktabschnitt gebildet, insbesondere aus einem Kontaktträgerband geformt.In one embodiment, the switching contact arrangement comprises a first offset section which is arranged on the first contact plug and is designed to offset the first contact plug along a surface normal of the first switching plane by a predetermined distance from the first switching plane. The first offset section is in particular formed in one piece with the first contact plug and / or the first contact section, in particular formed from a contact carrier strip.

Mit dem ersten Versatzabschnitt kann der erste Kontaktstecker an einer vorbestimmten Position der Relaisbreite angeordnet sein. Insbesondere kann der erste Kontaktstecker in der ersten Schaltebene, in der zweiten Schaltebene oder mittig zwischen der ersten Schaltebene und der zweiten Schaltebene angeordnet sein. Ferner ist eine beliebige vorbestimmte Position des ersten Kontaktträgers begrenzt durch die Breite des Relais realisierbar. Dadurch kann die Position des ersten Kontaktträgers in vorteilhafterweise an eine Position einer zugehörigen Kontaktbuchse in einer Reihenklemme zur Aufnahme des Relais angepasst sein. Ferner können auch der zweite Kontaktstecker und/oder der dritte Kontaktstecker über einen jeweiligen Versatzabschnitt in einer vorbestimmten Position angeordnet werden.

In einer Ausführungsform sind die Kontaktstecker jeweils versetzt zueinander angeordnet.With the first offset section, the first contact plug can be arranged at a predetermined position of the relay width. In particular, the first contact plug can be arranged in the first switching level, in the second switching level or in the middle between the first switching level and the second switching level. Furthermore, any predetermined position of the first contact carrier, limited by the width of the relay, can be realized. As a result, the position of the first contact carrier can advantageously be adapted to a position of an associated contact socket in a terminal block for receiving the relay. Furthermore, the second contact plug and / or the third contact plug can also be arranged in a predetermined position via a respective offset section. The first contact plug, the second contact plug and the third contact plug are advantageously arranged in one plane. In one embodiment, the contact plugs are each arranged offset to one another.

The offset sections are designed to dispose the respective contact plug along a surface normal of the first switching plane offset by a predetermined distance from the first switching plane.

Mittels der seitlich versetzten Anordnung des dritten Versatzabschnittes kann vorteilhafterweise der in Längsrichtung der Kontaktfeder zur Verfügung stehende Bauraum für eine Befestigung der Kontaktfeder und/oder für eine Ausbildung des Federelements genutzt werden. Insbesondere wird durch den Versatzabschnitt, der in Längsrichtung der Kontaktfeder zur Verfügung stehende Bauraum nicht reduziert. Effizienter Weise kann der dritte Versatzabschnitt quer zur Längsrichtung der Kontaktfeder versetzt angeordnet sein, um Bauraum effizient zu nutzen, welcher durch den Mindestabstand der Kontaktstecker zueinander gegeben ist.By means of the laterally offset arrangement of the third offset section, the installation space available in the longitudinal direction of the contact spring can advantageously be used for fastening the contact spring and / or for forming the spring element. In particular, the installation space available in the longitudinal direction of the contact spring is not reduced by the offset section. The third offset section can be arranged offset transversely to the longitudinal direction of the contact spring in an efficient manner in order to efficiently use installation space which is given by the minimum distance between the contact plugs.
