Description
Die Erfindung betrifft einen Kurzhubschalter mit einem Hebel, bestehend aus einer Grundplatte und einem senkrecht von der Vorderseite der Grundplatte abstehenden Betätigungsstift, und mit einer Leiterplatte, auf der mindestens ein elektrisches Schaltelement angeordnet ist, das durch eine Schwenkbewegung des Hebels betätigbar ist, wobei ein Endabschnitt des Betätigungsstifts eine Ausnehmung eines Gehäuseteils durchragt.The invention relates to a short-stroke switch with a lever, consisting of a base plate and an actuating pin protruding perpendicularly from the front of the base plate, and with a printed circuit board on which at least one electrical switching element is arranged, which can be actuated by a pivoting movement of the lever, an end section of the actuating pin extends through a recess of a housing part.
Ein derartiger Kurzhubschalter ist aus der Patentschrift
Für viele Anwendungen, insbesondere in Kraftfahrzeugen, sind besonders Kurzhubschalter erwünscht, die sich durch einen sehr einfachen und kostengünstigen Aufbau, eine hohe Zuverlässigkeit und sehr kurze Betätigungswege auszeichnen.For many applications, especially in motor vehicles, short-stroke switches are particularly desirable, which are characterized by a very simple and inexpensive structure, a high level of reliability and very short actuation paths.
Es stellte sich die Aufgabe, einen gattungsgemäßen Kurzhubschalter zu schaffen, der diese Anforderungen in hohem Maße erfüllt.The task was to create a generic short-stroke switch that meets these requirements to a high degree.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das mindestens eine Schaltelement durch jeweils eine Schnappscheibe und Kontaktflächen auf der Leiterplatte ausgebildet ist, dass die Vorderseite der Grundplatte um den Betätigungsstift herum einstückig angeformte Kugelflächenabschnitte aufweist, die an komplementär geformten konkaven Flächenabschnitten an der Innenseite des Gehäuseteils anliegen, und dass die Rückseite der Grundplatte unterhalb des Betätigungsstifts eine einstückig angeformte Kugelkalotte oder Abschnitte einer Kugelkalotte aufweist, die auf der Leiterplatte aufliegt/aufliegen.This object is achieved according to the invention in that the at least one switching element is formed by a snap disk and contact surfaces on the printed circuit board, that the front of the base plate has integrally formed spherical surface sections around the actuating pin, which bear against complementarily shaped concave surface sections on the inside of the housing part , and that the back of the base plate below the actuating pin has an integrally formed spherical cap or sections of a spherical cap which rests on the printed circuit board.
Die an der Grundplatte angeformten Kugelflächenabschnitte und die konkaven Flächenabschnitte am Gehäuseteil schaffen zusammen mit der Kugelkalotte, die auf der Leiterplatte aufliegt, auf einfache Weise eine präzise Schwenklagerung des aus Betätigungsstift und Grundplatte bestehenden Hebels.The spherical surface sections formed on the base plate and the concave surface sections on the housing part, together with the spherical cap which rests on the printed circuit board, easily create a precise pivot bearing of the lever consisting of the actuating pin and the base plate.
Die Kugelkalotte ist dazu vorzugsweise als eine einstückig an die Rückseite der Grundplatte angeformte Halbkugel ausgebildet. Anstelle einer vollständigen Kugelkalotte können an der Rückseite der Grundplatte auch ein oder mehrere Abschnitte einer Kugelkalotte angeformt sein, die derart geformt und ausgerichtet sind, dass sie in den vorgesehenen Schwenkrichtungen des Hebels auf der Leiterplatte abrollen können.For this purpose, the spherical cap is preferably designed as a hemisphere integrally formed on the back of the base plate. Instead of a complete spherical cap, one or more sections of a spherical cap can also be formed on the back of the base plate, which are shaped and aligned in such a way that they can roll on the circuit board in the intended pivoting directions of the lever.
Zusätzlich vorteilhaft ist die Ausbildung der Schaltelemente mittels Schnappscheiben, da sich Schnappscheiben mit sehr kurzen Betätigungswegen realisieren lassen.The formation of the switching elements by means of snap disks is also advantageous, since snap disks can be implemented with very short actuation paths.
Als Betätigungselemente für die Schnappscheiben können vorteilhafterweise weitere Kugelkalotten an der Rückseite der Grundplatte angeformt sein. Der Radius der Kugelkalotte unterhalb des Betätigungsstifts und die Radien der als Betätigungselemente vorgesehenen weiteren Kugelkalotten können, unter Berücksichtigung der Bauhöhe der Schnappscheiben, so aufeinander abgestimmt sein, dass in der unbetätigten Ruheposition des Schalters alle Betätigungselemente auf den Schnappscheiben aufliegen, ohne diese zu betätigen. Dabei werden das Eigengewicht des Hebels, sowie auch axiale Krafteinwirkungen auf den Betätigungsstift des Hebels, welche zu keiner Schalterbetätigungen führen sollen, durch die auf der Leiterplatte aufliegende Kugelkalotte unterhalb des Betätigungsstift abgestützt.Further spherical caps can advantageously be integrally formed on the rear of the base plate as actuating elements for the snap disks. The radius of the spherical cap below the actuating pin and the radii of the further spherical spheres provided as actuating elements can be coordinated with one another, taking into account the overall height of the snap disks, so that all actuating elements rest on the snap disks in the unactuated rest position of the switch without actuating them. The dead weight of the lever, as well as axial forces acting on the actuating pin of the lever, which should not result in any switch actuation, are supported by the spherical cap resting on the circuit board below the actuating pin.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen eines erfindungsgemäßen Kurzhubschalters gehen aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung der Figuren hervor.Further advantageous refinements and developments of a short-stroke switch according to the invention emerge from the subclaims and from the following description of the figures.
