Description

Die Erfindung betrifft einen elektrischen Schalter nach dem Oberbegriff des Patentanspruchs 1 (DE-A-19 646 474).The invention relates to an electrical switch according to the Preamble of claim 1 (DE-A-19 646 474).

Bei elektrischen Geräten, die unter rauhen Betriebsbedingungen eingesetzt werden, sind Vorkehrungen zu treffen, so daß der elektrische Schalter vor schädlichen Einflüssen, die seine Funktionsfähigkeit beeinträchtigen, geschützt ist. Beispielsweise kann es sich bei solchen schädlichen Einflüssen um Feuchtigkeit, Staub o. dgl. handeln.For electrical devices that are rough under Precautions must be taken when operating conditions are used hit so that the electrical switch from harmful Influences that impair its functionality, is protected. For example, such harmful influences around moisture, dust or the like act.

Solche Schalter besitzen ein Gehäuse, in dem das Kontaktsystem befindlich ist, sowie ein in einer Öffnung am Gehäuse angeordnetes, teilweise aus dem Gehäuse herausragenden Betätigungsorgan zum schaltenden Einwirken auf das Kontaktsystem. Zum Schutz des Schalters vor schädlichen Einflüssen ist am Schalter eine Kappe aus elastischem Material angeordnet, die den aus dem Gehäuse ragenden Teil des Betätigungsorgans sowie die Öffnung im Gehäuse überdeckt. Aufgrund ihrer Elastizität gestattet die Kappe die Bewegung des Betätigungsorgans zum Schalten des Kontaktsystems.Such switches have a housing in which the Contact system is located, as well as in an opening on Housing arranged, partially from the housing outstanding actuator for switching action the contact system. To protect the switch from harmful Influences is a cap made of elastic on the switch Material arranged, the part protruding from the housing of the actuator and the opening in the housing covered. Due to its elasticity, the cap allows movement of the actuator for switching the contact system.

Nachteilig bei der bekannten Kappe zum Schutz des Schalters vor Schadstoffen ist, daß bei Betätigung des Schalters eine Relativbewegung zwischen der Kappe und dem Betätigungsorgan stattfindet. Dadurch kann eine Zerstörung der Kappe nach einer gewissen Gebrauchsdauer auftreten, insbesondere kann die Reibung zwischen der Kappe und dem Betätigungsorgan zu Rissen in der Kappe führen, so daß die Kappe ihre Schutzfunktion nicht mehr erfüllen kann. Weiterhin ist es nachteilig, daß aufgrund der Elastizität der Kappe optisch nur schwer zu erkennen ist, welchen Schaltzustand das Betätigungsorgan einnimmt.A disadvantage of the known cap for protecting the switch before pollutants is that when the switch is actuated Relative movement between the cap and the actuator takes place. This can destroy the cap after a certain period of use, in particular can occur the friction between the cap and the actuator Make cracks in the cap so that the cap is yours Protective function can no longer fulfill. Furthermore it is disadvantageous that optically due to the elasticity of the cap it is difficult to see which switching state it is Actuator occupies.

Aus der DE 196 46 474 A1 ist weiter ein elektrischer Schalter mit einer Kappe bekannt, die einen Deckel aus einem harten Werkstoff und ein in der Art eines Faltenbalgs ausgebildetes hülsenartiges Teil aus einem flexiblen Werkstoff besitzt. Der Deckel der Kappe ist an der benutzerabgewandten Seite topfförmig ausgestaltet und so an dem aus der Öffnung herausragenden Teil des Betätigungsorgans angeordnet, daß das hülsenartige Teil vom Deckel überdeckt ist. Das Betätigungsorgan ist über die benutzerzugewandte Seite des Deckels zum Schalten des Kontaktsystems bewegbar. Diese Ausgestaltung der Kappe bedingt eine große Bauform für den Schalter. Zudem besteht die Gefahr, daß sich Schadstoffe im topfförmigen Teil des Deckels ansammeln und in das Gehäuse des Schalters eindringen.From DE 196 46 474 A1 there is also an electrical switch known with a cap that made a lid from a hard Material and a bellows-type has sleeve-like part made of a flexible material. The The lid of the cap is on the side facing away from the user Pot-shaped and so on the out of the opening protruding part of the actuator arranged that the sleeve-like part is covered by the lid. The Actuator is on the user side of the Movable cover for switching the contact system. This Design of the cap requires a large design for the Switch. In addition, there is a risk that pollutants in Collect the pot-shaped part of the lid and into the housing of the switch penetrate.

Der Erfindung liegt die Aufgabe zugrunde, den elektrischen Schalter derart weiter zu entwickeln, daß der Schutz vor Eindringen von Schadstoffen in den Schalter verbessert ist. Außerdem soll ein kleinbauender Schalter dieser Art geschaffen werden.The invention has for its object the electrical Switch to develop in such a way that protection against Penetration of contaminants in the switch is improved. In addition, a small switch of this type be created.

Diese Aufgabe wird bei einem gattungsgemäßen elektrischen Schalter durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is done in a generic electrical Switch by the characterizing features of claim 1 solved.

Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further refinements of the invention are the subject of Dependent claims.

Zweckmäßigerweise wird als Werkstoff für die ebene Fläche des Deckels ein starrer Kunststoff und für das hülsenartige Teil ein flexibler Kunststoff, wie ein thermoplastisches Elastomer, gewählt. Es bietet sich dann an, das eine Ende des hülsenartigen Teils zur Befestigung in der Art eines Zwei-Komponenten-Teils an der ebenen Fläche des Deckels anzuspritzen. Die Gefahr, daß Schadstoffe an der besonders beanspruchten Befestigungsstelle zwischen dem Deckel und dem hülsenartigen Teil eindringen, ist dadurch sehr gering.Appropriately, as a material for the flat surface of the Cover a rigid plastic and for the sleeve-like part a flexible plastic, like a thermoplastic Elastomer, selected. It then lends itself to one end of the sleeve-like part for attachment in the manner of a two-component part on the flat surface of the lid to mold. The danger that pollutants on the particular claimed attachment point between the lid and the penetrate sleeve-like part is very low.

Die ebene Fläche des Deckels kann an der benutzerabgewandten Seite mittels Rast- und/oder Schnappelemente am Betätigungsorgan befestigt sein. Dadurch ist eine einfache Montage lediglich durch Aufstecken der Kappe ermöglicht, wobei vorteilhafterweise eine Beeinträchtigung der Schutzfunktion der Kappe nicht zu befürchten ist. Das dem Gehäuse zugewandte, andere Ende des hülsenartigen Teils kann an einer Flanschfläche des Gehäuses auf einfache Art und Weise überstülpbar oder auch mittels eines rahmenartigen Sockels aufsteckbar ausgebildet sein.The flat surface of the lid can face away from the user Page by means of locking and / or snap elements on Actuator be attached. This makes it easy Assembly only possible by attaching the cap, advantageously an impairment of the Protective function of the cap is not to be feared. That the Housing facing, other end of the sleeve-like part can on a flange surface of the housing in a simple manner and Can be slipped on or by means of a frame-like one Base be designed to be pluggable.

Zur zusätzlichen Verbesserung der Abdichtung der Montageöffnung eines Gerätes, in die der Schalter eingesetzt ist, kann eine Dichtlippe am anderen Ende des hülsenartigen Teils beziehungsweise am rahmenartigen Sockel angeordnet sein. Weiter ist es auch möglich, den Schalter derart in die Montageöffnung einzusetzen, daß ein Teil des hülsenartigen Teils an der Kappe gleichzeitig die Montageöffnung in das Innere des Gerätes abdichtet. Dadurch ist auf einfache Art und Weise lediglich durch Verwendung des Schalters das Eindringen von Schadstoffen in das Gerät verhindert, ohne daß zusätzliche Abdichtmittel für das Gerät notwendig wären.To further improve the sealing of the Installation opening of a device in which the switch is inserted is, a sealing lip at the other end of the sleeve-like Partly or arranged on the frame-like base his. It is also possible to insert the switch in such a way Insert mounting hole that part of the sleeve-like Part of the cap at the same time the mounting opening in the Seals inside the device. This makes it easy and only by using the switch Prevents pollutants from entering the device without additional sealants for the device would be necessary.

Der erfindungsgemäße Schalter läßt sich auch auf einfache Art und Weise beleuchtbar ausgestalten, wobei dennoch der Schutz vor Eindringen von Schadstoffen vollständig erhalten ist. Hierzu genügt es, die ebene Fläche des Deckels aus einem für Licht im sichtbaren Spektralbereich wenigstens teilweise durchlässigen Kunststoff herzustellen. Das Leuchtmittel kann in einer Kammer des Betätigungsorgans angeordnet sein, wobei die Kammer von der ebenen Fläche des Deckels überdeckt ist. Zur Steigerung der Lichtausbeute bei einem solchermaßen beleuchtbaren Schalter bietet es sich dann weiter an, das hülsenartige Teil aus einem für Licht im sichtbaren Spektralbereich im wesentlichen undurchlässigen Kunststoff herzustellen.The switch according to the invention can also be simple and fashionable illuminated, while still protecting completely preserved before the ingress of pollutants. To do this, it is sufficient to remove the flat surface of the cover from a Light in the visible spectral range at least partially to produce permeable plastic. The lamp can be arranged in a chamber of the actuator, wherein the chamber is covered by the flat surface of the lid. To increase the light output in such a way Illuminated switch, it then offers itself that sleeve-like part made of one for light in the visible Spectral range of essentially impermeable plastic manufacture.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein verbesserter Schutz vor Eindringen von Schadstoffen in das Gehäuseinnere des Schalters, was zu Beeinträchtigungen des im Gehäuse befindlichen Kontaktsystems führen kann, erreicht wird. Die Gefahr, während der Gebrauchsdauer des Schalters, die Kappe zu beschädigen, ist durch die als Betätigungsfläche dienende, harte ebene Fläche des Deckels der Kappe stark reduziert. Daneben ist auch ein gleichzeitiger Schutz des elektrischen Gerätes, in dessen Wandung der Schalter in einer Montageöffnung einsetzbar ist, vor Eindringen von Schadstoffen durch die Montageöffnung erzielbar. Zudem wird durch die Verbesserung des Schutzes für den Schalter dessen Lebensdauer beträchtlich erhöht.The advantages achieved with the invention exist especially in that improved protection from Penetration of pollutants into the interior of the Switch, which adversely affects the housing located contact system can be achieved. The Danger, during the life of the switch, the cap is to be damaged by the hard flat surface of the lid of the cap is greatly reduced. There is also a simultaneous protection of the electrical Device, in the wall of the switch in one Mounting opening can be used before intrusion of Pollutants can be achieved through the assembly opening. In addition, by improving protection for the switch of that Service life increased considerably.

Gegenüber den bisher verwendeten elastischen Kappen, bei denen die jeweilige Schaltstellung des Betätigungsorgans nur sehr schwer optisch erkennbar ist, ist beim erfindungsgemäßen Schalter die eingenommene Schaltstellung des Betätigungsorgans gut sichtbar. Bei einem beleuchteten Schalter wird das Licht der Beleuchtung weniger stark gedämpft als es bei den bisherigen elastischen Kappen der Fall ist.Compared to the previously used elastic caps, at which the respective switching position of the actuator only is very difficult to recognize optically, is in the invention Switch the switch position it occupies Actuator clearly visible. With an illuminated Switch, the light of the lighting becomes less strong dampened than it was with the previous elastic caps of the Case is.

Aufgrund der als Betätigungsfläche dienenden harten ebene Fläche des Deckels der Kappe ist der erfindungsgemäße Schalter besser vom Benutzer zu betätigen. Das Betätigungsgefühl entspricht demjenigen eines Schalters, bei dem der Benutzer direkt auf das Betätigungsorgan einwirkt, womit nicht das bei einem Schalter mit der herkömmlichen elastischen Kappe undefinierbare Betätigungsgefühl auftritt. Weiterhin wird eine Dämpfung der beim Betätigen des Betätigungsorgans erzeugten Schaltgeräusche bewirkt, so daß beim erfindungsgemäßen Schalter die Ergonomie für den Benutzer verbessert ist.Due to the hard level serving as the operating surface The surface of the lid of the cap is that of the invention Switch better to be operated by the user. The Actuation feeling corresponds to that of a switch, at which the user acts directly on the actuator, which is not the case with a switch with the conventional one elastic cap indefinable actuation sensation occurs. Furthermore, a damping of the actuation of the Actuator generated switching noise, so that in the switch according to the invention, the ergonomics for the User is improved.

Trotz der Abdichtung gegenüber Schadstoffen kann der erfindungsgemäße Schalter kleinbauender als ein bisheriger geschützter Schalter ausgestaltet werden. Schließlich ist für den Benutzer gut sichtbar, daß der Schalter vor Eindringen von Schadstoffen geschützt ist, selbst wenn der Schalter in die Wandung eines elektrischen Gerätes eingebaut ist. Dennoch ist gegenüber den herkömmlichen Schutzkappen die Ästhetik für den Schalter verbessert.Despite the sealing against pollutants, the Switch according to the invention more compact than a previous one protected switch can be designed. After all, is for clearly visible to the user that the switch from intrusion is protected from harmful substances, even if the switch is in the wall of an electrical device is installed. Yet is the aesthetic for conventional protective caps improved the switch.
