Description

Die Erfindung bezieht sich auf einen elektrischen Schalter mit einem in einem Gehäuse verschiebbar gelagerten Betätigungselement, das über Schaltnocken zugeordnete, mit Anschlußkontakten in Verbindung stehende Schaltkontakte beaufschlagt, wobei zwischen jedem Schaltnocken und dem zugeordneten Schaltkontakt ein endseitig gehäusefester Betätiger angeordnet ist, dessen freies Ende den Schaltkontakt beaufschlagt, und der einen zu einem zugeordneten Schaltnocken korrespondierenden Nocken trägt.The invention relates to an electrical switch with a displaceably mounted in a housing actuator, which is associated with switching cams associated with terminal contacts switching contacts, wherein between each switching cam and the associated switching contact an end fixed to the housing actuator is arranged, the free end of the switch contact acted upon, and carries a cam corresponding to an associated switching cam.

Solche Schalter werden oftmals als Spiegelverstellschalter oder Sitzverstellschalter in Kraftfahrzeugen eingesetzt, wobei ein Betätigungselement in der Regel in mehrere Richtungen verschiebbar ist, um unterschiedliche Schaltfunktionen in einem Schalter zu realisieren. Nach dem Loslassen des Betätigungselementes kehrt dieses in seine Null-Lage zurück. Zur Ausführung der Schaltfunktionen ist zwischen dem Betätigungselement und zugeordneten Schaltkontakte mindestens ein Schaltglied angeordnet. Das Schaltglied dient zur Umformung der horizontalen Schiebebewegungen des Betätigungselementes in vertikale Beaufschlagungsrichtungen für zugeordnete Schaltkontakte. Als nachteilig erweist sich die Anordnung der Schaltkontakte, die einem Boden eines Gehäuses des Schalters in einem relativ großen Abstand zueinander zugeordnet sind. Aufgrund dieser Anordnung der Schaltkontakte ist entweder eine relativ große, die Schaltkontakte tragende Leiterplatte oder ein in den gesamten Boden des Gehäuses eingelassenes Stanzgitter zur Kontaktierung der Anschlußkontakte notwendig, wodurch der Schalter einen entsprechend umfangreichen und somit teuren Aufbau aufweist.Such switches are often used as Spiegelverstellschalter or Sitzverstellschalter in motor vehicles, wherein an actuating element is generally displaceable in several directions in order to realize different switching functions in a switch. After releasing the actuator this returns to its zero position. To execute the switching functions, at least one switching element is arranged between the actuating element and associated switching contacts. The switching element is used to reshape the horizontal sliding movements of the actuating element in vertical loading directions for associated switching contacts. A disadvantage, the arrangement proves the Switch contacts, which are associated with a bottom of a housing of the switch at a relatively large distance from each other. Due to this arrangement of the switching contacts either a relatively large, the switch contacts carrying circuit board or a recessed in the entire bottom of the housing stamped grid for contacting the terminal contacts is necessary, whereby the switch has a correspondingly extensive and therefore expensive construction.

Im weiteren wird der Aufbau des Schalters durch die Anordnung von mindestens einem Schaltglied im Inneren des Gehäuses komplexer. Um die Rückstellbewegung des Betätigungselementes in die Null-Lage sicherzustellen, wirkt das Betätigungselement mit einer Schaltkulisse zusammen oder das Schaltelement ist entsprechend federbelastet und bewirkt die Rückstellung des Betätigungselementes. Die Anordnung des Schaltgliedes ist weiterhin notwendig, um bei einem relativ kleinen Schaltweg des Schaltkontaktes einen hinreichend großen Verschiebeweg des Betätigungselementes zu ermöglichen.In addition, the structure of the switch by the arrangement of at least one switching element in the interior of the housing is complex. In order to ensure the return movement of the actuating element in the zero position, the actuating element cooperates with a shift gate or the switching element is spring-loaded and causes the return of the actuating element. The arrangement of the switching element is further necessary to allow a sufficiently large displacement of the actuating element at a relatively small switching path of the switching contact.

Aus der US-A-5 147 990 ist ein elektrischer Schalter mit einem in einem Gehäuse verschiebbar gelagerten Betätigungselement bekannt, das über einen Schaltnocken zugeordnete, mit Anschlusskontakten in Verbindung stehende Schaltkontakte beaufschlagt. Zwischen dem Schaltnocken und dem zugeordneten Schaltkontakt ist ein endseitig gehäusefester Betätiger angeordnet, dessen freies Ende den Schaltkontakt beaufschlagt, wobei in der Betätiger einen einem Schaltkontakt zugeordneten Nocken trägt. In einer ersten Ausführungsform des Schalters sind zwei Betätiger diametral gegenüberliegend in einem Gehäuse befestigt. In einer zweiten Ausführungsform des Schalters sind zwei Betätigerversetzt zueinander an gegenüberliegenden Gehäusewänden befestigt. Beim Hin- und Herschieben des Betätigungselementes wird jeweils einer der Betätiger beaufschlagt.From US-A-5 147 990 an electrical switch with a displaceably mounted in a housing actuator is known, which acts on a switching cam associated with terminal contacts in connection with switching contacts acted upon. Between the switching cam and the associated switching contact an end fixed to the housing actuator is arranged, the free end of which acts on the switching contact, wherein in the actuator carries a cam associated with a switching contact. In a first embodiment of the switch, two actuators are mounted diametrically opposite one another in a housing. In a second embodiment of the switch two actuators offset to each other on opposite housing walls. When pushing back and forth of the actuating element in each case one of the actuators is acted upon.

Die DE 34 11 597 A1 beschreibt einen Schiebeschalter mit einem Gehäuse, in den ein Betätigungselement verschiebbar gelagert ist. In dem Gehäuse sind schwenkbar gelagerte Betätiger federbelastet zur Beaufschlagung von zugeordneten Schaltkontakten angeordnet. Die Betätiger sind winkelförmig ausgebildet, wobei ein erster Arm einen dem Schaltkontakt zugeordneten Nocken aufweist und ein zweiter Arm als Feder ausgebildet ist und sich in einem Schlitz des Gehäuses abstützt. An der Verbindungsstelle der Arme ist ein Lager ausgebildet, mit dem die Betätiger auf einer gehäusefesten Achse schwenkbar gelagert sind. Beim Verschieben des Betätigungselementes gelang eine daran ausgebildete Ausnehmung in verrastenden Eingriff mit einer Nase des ersten Armes des Betätigers. Hierbei wird der erste Arm zur Betätigung des zugeordneten Schaltkontaktes entgegen der federnden Wirkung des zweiten Armes beaufschlagt.DE 34 11 597 A1 describes a slide switch with a housing in which an actuating element is slidably mounted. In the housing pivotally mounted actuators spring loaded to act on associated switching contacts are arranged. The actuators are angularly formed, wherein a first arm has a switching contact associated cam and a second arm is formed as a spring and is supported in a slot of the housing. At the junction of the arms, a bearing is formed, with which the actuators are pivotally mounted on a housing-fixed axis. When moving the actuator succeeds a recess formed in latching engagement with a nose of the first arm of the actuator. Here, the first arm is acted upon to actuate the associated switching contact against the resilient action of the second arm.

Es ist Aufgabe der Erfindung, einen elektrischen Schalter der eingangs genannten Art zu schaffen, der bei einer gewährleisteten Funktionssicherheit einen relativ einfachen und somit kostengünstigen Aufbau aufweist.It is an object of the invention to provide an electrical switch of the type mentioned, which has a relatively simple and thus inexpensive construction with a guaranteed reliability.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß

  • das Betätigungselement kreuzweise verschiebbar in dem Gehäuse gelagert ist, wobei zumindest in jeder Schieberichtung jeweils ein Schaltkontakt beaufschlagbar ist und
  • die Schaltkontakte parallel sowie unmittelbar benachbart zu einer seitlichen Gehäusewand angeordnet und die Betätiger an einer gegenüberliegenden Gehäusewand einstückig angeformt sind.
According to the invention the object is achieved in that
  • the actuating element is mounted crosswise displaceable in the housing, wherein at least in each sliding direction in each case a switching contact can be acted upon and
  • the switching contacts arranged in parallel and immediately adjacent to a lateral housing wall and the actuators are integrally formed on an opposite housing wall.

Der gehäusefeste Betätiger wirkt somit wie eine einseitig eingespannte Blattfeder und formt durch seinen Nocken die von dem Betätigungselement über dessen Schaltnocken eingeleitete horizontale Schiebebewegung in eine vertikale Schaltbewegung zur.Beaufschlagung des zugeordneten Schaltkontaktes um. Ferner bewirkt der Betätiger aufgrund seiner Elastizität die Rückstellbewegung des ßetätigungselementes nach dessen Loslassen. Durch die Anordnung der Schaltkontakte ist es möglich, die für die Schaltkontakte benötigten elektrischen Verbindungen ebenfalls auf diese relativ kleine Fläche zu begrenzen. Der Hebelweg der Betätiger ist auf die für die Schaltvorgange benötigten Kraft- und Wogeverhältnisse abgestimmt. Aufgrund der Anformung der Betätiger an einer Gehäusewand ist keine zusätzliche Montage zur Anordnung der Betätiger notwetldig ist. Die kreuzweise Verschiebbarkeit des Betätigungselementes stellt sicher, daß eine Vielzahl von Schaltvorgängen durch unterschiedliche, sinnfällige Betätigungsrichtungen des Betätigungselementes ausgeführt werden können, wobei die Schaltkontakte unabhängig von den Betätigungsrichtungen angeordnet sind.The housing-fixed actuator thus acts as a cantilevered leaf spring and formed by its cam initiated by the actuator via the switching cam horizontal sliding movement in a vertical switching movement for. Feeding the associated switching contact to. Furthermore, the actuator causes due to its elasticity, the return movement of ßetätigungselementes after its release. The arrangement of the switching contacts, it is possible to limit the electrical connections required for the switching contacts also on this relatively small area. The lever travel of the actuator is tuned to the force and wave conditions required for the shifting process. Due to the molding of the actuator on a housing wall no additional assembly for the arrangement of the actuator is notwetldig. The crosswise displaceability of the actuating element ensures that a plurality of switching operations can be performed by different, obvious actuating directions of the actuating element, wherein the switching contacts are arranged independently of the actuating directions.

Um die Funktionssicherheit des Schalters weiterhin zu erhöhen, tragen nach einer Ausgestaltung der Erfindung die Schaltnocken und die Nocken auf ihren benachbarten Flächen gegenläufige schiefe Ebenen. Die flächenmäßige Auflage des Schaltnockens auf dem zugeordneten Nocken führt gegenüber einner punktuellen Auflage zu einer Verbesserung der Schaltsicherheit. Über die Gestaltung der Neigung der korrespondierenden schiefen Ebenen lassen sich die Haptik und die Übersetzung des Betätigungsweges zu dem Schaltweg abstimmen.In order to further increase the reliability of the switch, wear according to an embodiment of the invention, the switching cams and the cams on their adjacent surfaces opposite inclined planes. The areal edition of the switching cam on the associated cam leads to one Selective edition to improve the switching reliability. About the design of the inclination of the corresponding inclined planes, the feel and the translation of the actuation path can be tuned to the switching path.

Nach einer vorteilhaften Weiterbildung der Erfindung sind die Betätiger aus Kunststoff gefertigt und an der zugeordneten Gehäusewand angeformt. Das Gehäuse wird mitsamt den Betätigern in einem Arbeitsgang als Spritzgußteil gefertigt.According to an advantageous embodiment of the invention, the actuators are made of plastic and formed on the associated housing wall. The housing is manufactured together with the actuators in one operation as an injection molded part.

Um eine linien- oder punktförmige Beaufschlagung des Schaltelementes zu erzielen, trägt zweckmäßigerweise jeder Betätiger an seinem freien Ende einen auf den Schaltkontakt wirkenden Ansatz.To achieve a linear or punctiform loading of the switching element, suitably carries each actuator at its free end acting on the switching contact approach.

Bevorzugt ist das Betätigungselement verdrehbar in dem Gehäuse gelagert.Preferably, the actuating element is rotatably mounted in the housing.

Zweckmäßigerweise wirkt das Betätigungselement mit Federelementen zusammen. Die Federelemente sind zur Beeinflussung des taktilen Schaltempfindens vorgesehen.Conveniently, the actuating element cooperates with spring elements. The spring elements are provided for influencing the tactile switching sensation.

Zur Erzielung einer einfachen Lagerung des Betätigungselementes bei gleichzeitig einfachem Aufbau desselben, umfaßt das Betätigungselement ein Griffstück und eine Betätigungsplatte mit zwischengeordnetem Führungsansatz, wobei der Führungsansatz gehäuseseitig gelagert ist. Somit stellen das Griffstück und die Betätigungsplatte im wesentlichen die horizontale und der Führungsansatz die vertikale Führung des Betätigungselementes sicher.To achieve a simple storage of the actuating element while the same simple structure, the actuating element comprises a handle and an actuating plate with an intermediate guide lug, wherein the guide lug is mounted on the housing side. Thus, the handle and the actuator plate ensure the horizontal and the guide approach the vertical guidance of the actuator safely.

Bei einem relativ einfachen mechanischen Aufbau des Schalters ist der Führungsansatz in einem Deckel des Gehäuses mit Spiel gehalten. Darüberhinaus trägt bevorzugt die Betätigungsplatte die Schaltnocken. Sonach besteht der Schalter aus einer geringen Anzahl von Einzelbauteilen, wobei die Betätigungsplatte mitsamt den Schaltnocken einstückig im Kunststoffspritzgußverfahren herstellbar ist.With a relatively simple mechanical construction of the switch, the guide projection is held in a cover of the housing with play. In addition, preferably the actuator plate carries the switching cams. Sonach, the switch consists of a small number of individual components, wherein the actuating plate together with the switching cam is integrally produced by plastic injection molding.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Schaltkontakte in Dome einer Schaltmatte eingesetzt und beaufschlagen ein Stanzgitter oder eine Leiterplatte. Aufgrund der Materialeigenschaften der Schaltmatte und der konstruktiven Gestaltung der Dome ist beim Verschieben und/oder Verdrehen des Betätigungselementes ein Widerstand beim Beaufschlagen des Schaltkontaktes haptisch wahrnehmbar.According to a further advantageous embodiment of the invention, the switching contacts are used in domes of a switching mat and act on a stamped grid or a printed circuit board. Due to the material properties of the switching mat and the structural design of the dome, a resistance when applying the switching contact is haptically perceptible during displacement and / or rotation of the actuating element.

Nach einer alternativen Ausgestaltung sind die Schaltkontakte als einer Leiterplatte oder einem Stanzgitter zugeordnete Mikroschalter ausgebildet. Die Mikroschalter sind im Handel erhältlich und arbeiten bei geringstem Platzbedarf zuverlässig.According to an alternative embodiment, the switching contacts are formed as a printed circuit board or a lead frame associated microswitch. The microswitches are commercially available and work reliably in the smallest space requirement.

Um eine Vielzahl von Schaltkontakten auf einer relativ kleinen Grundfläche des Gehäuses anzuordnen, sind die durch die Schiebebewegung des Betätigungselementes beaufschlagten Schaltkontakte mit den zugeordneten Betätigern in einer anderen horizontalen Ebene des Gehäuses angeordnet als die durch die Drehbewegung beaufschlagten Schaltkontakte.To make a variety of switching contacts on a relatively small To arrange the base of the housing, the acted upon by the sliding movement of the actuating element switching contacts with the associated actuators in a different horizontal plane of the housing are arranged as acted upon by the rotational movement of the switching contacts.

Alternativ sind bevorzugt die durch die Schiebebewegung des Betätigungselementes beaufschlagten Schaltkontakte zu den durch die Drehbewegung beaufschlagten Schaltkontakte in einer Ebene sowie versetzt und die zugeordneten Betätiger in unterschiedlichen horizontalen Ebenen des Gehäuses angeordnet.Alternatively, preferably acted upon by the sliding movement of the actuating element switching contacts to the acted upon by the rotary switching contacts in a plane and offset and arranged the associated actuator in different horizontal planes of the housing.

Darüberhinaus resultiert aus einer entsprechenden Auslegung der korrespondierenden schiefen Ebenen 10, 19 eine bestimmte Übersetzung, also ein bestimmtes Verhältnis, zwischen einem Verschiebeweg des Betätigungselementes 1 und einem Beaufschlagungsweg des entsprechenden Schaltkontaktes 13. Somit ist es möglich, einen relativ großen Betätigungsweg des Betätigungselementes 1 bei einem relativ kleinen Beaufschlagungsweg der Schaltkontakte 13 zu erzielen.In order to reshape the vertical displacement direction of the actuating element 1 and thus the switching cam 9 in a horizontal loading direction of the corresponding actuator 11, the cam 20 of the actuator 11 are formed as inclined planes 19, wherein the inclined plane 19 of each actuator 11 to the inclined plane 10 of associated switching cam 9 and to the corresponding displacement direction of the actuating element 1 corresponds. In addition, resulting from a corresponding interpretation of the corresponding inclined planes 10, 19 a certain translation, so a certain ratio, between a displacement of the actuating element 1 and a Beaufschlagungsweg the corresponding switching contact 13. Thus, it is possible a relatively large actuation of the actuating element 1 at a To achieve relatively small admission of the switching contacts 13.

Der elektrische Schalter dient zur Steuerung nicht dargestellter Stellmotoren für Verstellbewegungen eines Sitzes 21 entsprechend den Doppelpfeilen 22, 23. Nach einem Verschieben des Betätigungselementes 1 in Richtung des Pfeils 24 erfolgt eine Beaufschlagung des zugeordneten Schaltkontaktes 13 durch das Niederdrücken des entsprechenden Betätigers 11 über den zugeordneten Schaltnocken 9 und den korrespondierenden Nocken 20, wonach ein Stellmotor den Sitz 21 nach vorne bewegt. Nach einem Verschieben des Betätigungselementes 1 in Richtung des Pfeils 25 verfährt ein Stellmotor den Sitz nach hinten, da der dieser Verschieberichtung zugeordnete Schaltkontakt 13 von dem entsprechenden Betätiger 11 beaufschlagt und sonach der Stellmotor angesteuert wird. Zum Anheben und Absenken des Sitzes 21 wird das Betätigungselement 1 gemäß den Richtungen der Pfeile 26, 27 verschoben, worauf eine Beaufschlagung des jeweils zugeordneten Schaltkontaktes 13 analog zu den zuvor geschilderten Vorgängen erfolgt.The electric switch is used to control actuators, not shown, for adjusting movements of a seat 21 corresponding to the double arrows 22, 23. After a displacement of the actuating element 1 in the direction of arrow 24, the associated switching contact 13 is acted upon by the depression of the corresponding actuator 11 via the associated switching cam 9 and the corresponding cam 20, after which a servomotor moves the seat 21 to the front. After a displacement of the actuating element 1 in the direction of the arrow 25, a servomotor moves the seat to the rear, since the direction of this shift associated switching contact 13 acted upon by the corresponding actuator 11 and therefore the servomotor is controlled. For raising and lowering the seat 21, the actuating element 1 is displaced in accordance with the directions of the arrows 26, 27, whereupon an action on the respective associated switching contact 13 takes place analogously to the previously described processes.

Die jeweilige Endlage des Betätigungselementes 1 in einer der Richtungen der Pfeile 24, 25, 26, 27 wird bei Anlage des Führungsansatzes 3 an dem entsprechenden Ende des Langloches 7 erreicht, wodurch die Schaltkontakte 13 vor einer mechanischen Überlastung geschützt sind. Aus jeder der Endlagen kehrt das Betätigungselement 1 aufgrund der Elastizität des Kunststoffes aus dem die Betätiger 11 gefertigt sind und die damit verbundene Rückstellbewegung des jeweils beaufschlagten Betätigers 11 in seine Null-Lage zurück, in dem die schiefe Ebene 10 des Schaltnockens 9 von der schiefen Ebene 19 des Nockens 20 des Betätigers 11 abgleitet.The respective end position of the actuating element 1 in one of the directions of the arrows 24, 25, 26, 27 is achieved when the guide projection 3 at the corresponding end of the slot 7, whereby the switching contacts 13 are protected against mechanical overload. From each of the end positions, the actuator 1 returns due to the elasticity of the plastic from which the actuator 11 are made and the associated return movement of each acted upon actuator 11 in its zero position, in which the inclined plane 10 of the switching cam 9 from the inclined plane 19 of the cam 20 of the actuator 11 slides off.
