Abstract
Description
Die vorliegende Erfindung betrifft einen elektrischen Schalter mit feststehenden und bewegbaren Kontaktelementen und mit einem Betätigungsglied, das ausgehend von einer Neutralstellung in zumindest einer Betätigungsrichtung mit zweistufigem Betätigungshub verstellbar ist und dessen der Betätigungsfläche abgewandte Unterseite über einen Ansatz außermittig mit der Kopffläche eines Betätigungselements zusammenwirkt, dessen Fußfläche an zwei Schaltdomen einer Domschaltmatte anliegt.The The present invention relates to a fixed-position electrical switch and movable contact elements and with an actuator, the starting from a neutral position in at least one actuating direction with two-stage operating stroke is adjustable and the actuating surface facing away from the underside of a Approach off-center with the head surface an actuating element interacts with the foot surface at two Schaltdomen a Domschaltmatte rests.

Hierbei treffen allerdings die Kontaktelemente der Schaltmatte, die üblicherweise jeweils die Form einer Kontaktpille aufweisen, nicht planparallel auf die Kontaktflächen der Leiterplatte auf. Dies hat zu Folge, daß sich der Übergangswiderstand zeitlich und mit dem Anpressdruck ändert. Bei einem spannungscodierten Schalter kann das zu einer Fehlfunktion der Elektronik führen. Um dennoch bei einem solchen Schalter zwischen den beweglichen und den feststehenden Kontaktelementen möglichst geringe und konstante Übergangswiderstände zu gewährleisten, hat es sich bewährt, alle Kontaktelemente mit einer Goldbeschichtung zu versehen. Dies ist zweckmäßig, aber relativ kostenaufwendig.in this connection However, meet the contact elements of the safety mat, usually each having the shape of a contact pill, not plane-parallel the contact surfaces the circuit board. This has the consequence that the contact resistance in time and changes with the contact pressure. With a voltage-coded switch, this can lead to a malfunction lead the electronics. Nevertheless, in such a switch between the movable and to ensure the lowest possible and constant contact resistance for the fixed contact elements, has it proven to provide all contact elements with a gold coating. This is functional, but relatively expensive.
Es stellte sich die Aufgabe, einen gattungsgemäßen elektrischen Schalter zu schaffen, der sich durch einen besonders einfachen und kostengünstigen Aufbau sowie durch eine besonders sichere Kontaktgabe mit geringen Übergangswiderständen auszeichnet.It set itself the task of a generic electric switch create a particularly simple and cost-effective Structure and characterized by a particularly secure contact with low contact resistance.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Betätigungselement elektrisch leitend ist und einstückig bewegliche Kontaktelemente ausbildet.These Task is inventively characterized solved, that this actuator is electrically conductive and in one piece forms movable contact elements.
Die Grundidee der Erfindung ist, die Goldkontaktpillen in der Schaltmatte durch eine Kontaktbrücke, die vorzugsweise einstückig aus Metall gebildet ist, zu substituieren.The The basic idea of the invention is the gold contact pills in the switching mat through a contact bridge, preferably in one piece made of metal is substituted.
In einer bevorzugten Ausführungsform ist die Kontaktbrücke als bügelförmige Metallkontaktbrücke ausgebildet. Diese ist derart geformt, daß eine Fläche außermittig von der Schaltwippe angesteuert werden kann und daß zwei abgewinkelte Endabschnitte durch Schaltdome der Schaltmatte hindurchtauchen. Beim Betätigen der Schaltwippe kollabiert als erstes der Schaltdom, auf der Seite mit dem kürzeren Hebelarm der Metallkontaktbrücke.In a preferred embodiment is the contact bridge designed as a bow-shaped metal contact bridge. This is shaped such that a area eccentrically can be controlled by the rocker switch and that two angled Immerse end sections through switching dome of the switching mat. When pressed the rocker switch collapses as the first of the switching dome, on the side with the shorter one Lever arm of the metal contact bridge.
Die Metallkontaktbrücke überbrückt dabei eine, auf der Leiterplatte befindliche, zweiteilige elektrische Kontaktfläche unterhalb des ersten Schaltdoms. Bei weiterer Betätigung der Schaltwippe bricht auch der zweite Schaltdom zusammen. Die Metallkontaktbrücke schließt auch hier einen zugehörigen Kontakt auf der Leiterplatte. Die Kontaktfläche unterhalb des zweiten Schaltdoms kann, genau wie die Kontaktfläche unterhalb des ersten Schaltdoms, zweiteilig ausgeführt sein.The Metal contact bridge bridges a, located on the circuit board, two-piece electrical contact area below the first switching dome. Upon further actuation of the Rocker also breaks the second switching dome together. The metal contact bridge also closes here an associated contact on the circuit board. The contact surface below the second switching dome can, just like the contact surface be executed below the first switching dome, in two parts.
Eine besonders vorteilhafte Ausgestaltung der Erfindung bezieht sich auf diese zweiten Kontaktfläche. Um Fertigungstoleranzen auszugleichen ist es vorteilhaft, wenn die Metallkontaktbrücke nur drei Punkte auf den Kontaktflächen der Leiterplatte kontaktiert. Hierbei wird die Tatsache ausgenutzt, daß die Metallkontaktbrücke nach Schließen des ersten Kontaktes, durch Verbinden der beiden Teile der zweiteiligen Kontaktfläche, bereits über ein elektrisches Potential verfügt. Dieses Potential wird an den zweiten Kontakt mit nur einer einteiligen Kontaktfläche auf der Leiterplatte weitergeleitet.A particularly advantageous embodiment of the invention relates on this second contact surface. To compensate for manufacturing tolerances, it is advantageous if the Metal contact bridge contacted only three points on the contact surfaces of the circuit board. Here, the fact is exploited that the metal contact bridge after Shut down of the first contact, by connecting the two parts of the two-piece Contact area, already over has an electrical potential. This potential will be at the second contact with only one piece contact area forwarded on the circuit board.
Durch die sich in der zweiten Betätigungsstufe ergebenden drei Auflagepunkte, steht die Metallkontaktbrücke statisch stabil auf der Leiterplatte und schließt sicher den ersten und zweiten Kontakt, unabhängig von Form- und Lagetoleranzen. Der Übergangswiderstand ist konstant, da die Berührungsflächen der ersten Kontaktelemente unabhängig von Betätigungswinkel und -kraft nahezu gleich groß bleiben.By which is in the second operating stage resulting in three contact points, the metal contact bridge is static stable on the circuit board and safely closes the first and second Contact, independent of shape and position tolerances. The contact resistance is constant, since the contact surfaces of the first contact elements independently of operating angle and strength remain almost the same size.
