Description

Die Erfindung betrifft ein elektrisches Haarpflegegerät mit einer Schalteranordnung zum Betätigen des Haarpflegegerätes, umfassend einen elektrischen Taster und einen zum Betätigen des Tasters beweglichen gegen die Kraft eines Federelements betätigbaren und in seiner Betätigungsstellung verriegelbaren Bedienknopf sowie ein durch den Bedienknopf betätigbares Stellglied umfasst.The invention relates to an electrical hair care device with a switch arrangement for operating the hair care device, comprising an electric Push button and one movable against the push of the button the force of a spring element can be actuated and in its actuation position lockable control button and one with the control button actuatable actuator comprises.

Elektrische Haarpflegegeräte, wie beispielsweise Haartrockner, Curler oder dergleichen können neben Schiebe- oder Wippschaltem auch Taster als zusätzliche Schalter aufweisen. Als zusätzlicher Schalter dient ein solcher Taster etwa bei einem Haartrockner als sogenannte Boost-Taste, um für die Zeitdauer des Betätigens dieser Taste die Geräteleistung zumeist kurzfristig zu erhöhen. Solche Tasten sind üblicherweise durch Schalteranordnungen realisiert, die zum einen diesen elektrischen Taster, auch als Mikroschalter ausgebildet sowie einen Bedienknopf umfassen, der verschieblich im Gehäuse des Handgerätes zum Betätigen des Tasters gelagert ist. Diese Schalteranordnungen arbeiten zufriedenstellend, weisen jedoch den Nachteil auf, dass diese für eine gewünschte längere Betätigung des Tasters grundsätzlich nicht arretierbar sind. Nicht unproblematisch ist bei einem Einsatz von Mikroschaltern auch, dass oftmals die Einbautoleranzen der Schalteranordnung in dem Gehäuse eines solchen elektrischen Handgerätes nicht unerheblich größer sind als der Schalthub eines Mikroschalters, der beispielsweise nur 0,5 mm betragen kann. Daher ist ein Einbau des Bedienknopfes zum Mikroschalter einer höheren Montagegenauigkeit unterworfen als eine Montage der übrigen Bestandteile eines solchen elektrischen Handgerätes. Dies ist unerwünscht, da eine solche Montage nur mit einem erheblichen Mehraufwand realisierbar wäre.Electric hair care devices, such as hair dryers, curlers or the like can push buttons or rocker switches have as additional switches. One serves as an additional switch Buttons on a hair dryer, for example, as a so-called boost button for the duration of pressing this button, the device performance mostly increase in the short term. Such buttons are usually through switch arrangements realized that on the one hand this electric button, too formed as a microswitch and include a control button that slidable in the housing of the hand-held device for pressing the button is stored. These switch arrangements work satisfactorily However, the disadvantage is that this is required for a longer operation the push button cannot be locked. Not without problems is also when using microswitches that often the Installation tolerances of the switch arrangement in the housing of such electrical handset are not insignificantly larger than the switching stroke a microswitch, which can be, for example, only 0.5 mm. Therefore is an installation of the control button to the microswitch of a higher one Assembly accuracy subject to assembly of the remaining components of such an electrical handheld device. This is undesirable because such an assembly can only be realized with considerable additional effort would.

Derartige Mikroschalter werden eingesetzt, da nur ein relativ geringer Einbauraum zur Verfügung steht. Zur Handhabung des Bedienknopfes eines solchen elektrischen Handgerätes ist es jedoch gewünscht, dass der Bewegungshub des Bedienknopfes größer ist als der Schalthub des Mikroschalters, um von einem Benutzer eine bewusste Betätigungsbewegung zur Betätigung des Mikroschalters abzuverlangen und um die Möglichkeit unerwünschter Tasterbetätigungen zu reduzieren.Such microswitches are used because they have only a relatively small installation space is available. For handling the control button one such an electrical hand-held device, however, it is desirable that the movement stroke the control button is larger than the switching stroke of the microswitch, to make a conscious actuation movement by a user to request the actuation of the microswitch and the possibility to reduce unwanted button operations.

Aus dem Bereich elektrisch angetriebener Handwerkzeuge ist durch DE 67 51 366 U1 eine Schalteranordnung bekannt geworden, die einen sich über eine Druckfeder auf einem Schaltergehäuse abstützenden Bedienknopf aufweist, der in lotrechter Richtung zum Taster bewegbar in einer Gehäuseschale gelagert ist. Der Taster wird mit der rückseitigen Stirnfläche des Bedienknopfes unmittelbar betätigt. Bei dieser Schalteranordnung ist der Bedienknopf in seiner Betätigungsstellung arretierbar, indem dieser um einige Winkelgrade in seiner Führung verstellt bzw. verkippt wird. In dieser Stellung hintergreift ein dem Bedienknopf zugeordneter Anschlag ein gehäuseseitig feststehendes Element, so dass eine ansonsten mögliche Rückstellung des Bedienknopfes durch die Federkraft verhindert ist.From the field of electrically powered hand tools by DE 67 51 366 U1 a switch arrangement has become known that one via a pressure spring on a switch housing supporting control button has, which is movable in a vertical direction to the button Housing shell is stored. The button comes with the back face of the control button operated immediately. With this switch arrangement the control button can be locked in its operating position by this is adjusted or tilted by a few degrees in its guidance. In a stop assigned to the control button engages behind this position a fixed element on the housing side, so that an otherwise possible Reset of the control button is prevented by the spring force.

Eine ähnliche Ausgestaltung einer Schalteranordnung ist aus US 4 879 438 A1 bekannt. Als Bedienknopf dient beim Gegenstand dieses Dokumentes ein nach Art einer Schwinge angelenkter Hebel, mit dessen Rückseite ein Taster betätigbar ist. An dem freien Ende dieses Bedienhebels ist schwenkbar gelagert ein Verriegelungshaken, mit dem der Bedienhebel in seiner den Taster betätigenden Stellung arretierbar ist. In dieser Stellung hintergreift der Haken einen Stift. Zum Erzielen der verriegelten Stellung des Bedienhebels ist in Betätigungsrichtung des Bedienhebels der Verriegelungshaken zum Öffnen betätigbar.A similar configuration of a switch arrangement is from US 4,879 438 A1 known. This document serves as a control button a lever articulated like a rocker, with the back of it a button can be operated. At the free end of this control lever is pivoted a locking hook with which the operating lever can be locked in its position actuating the button. In this position the hook engages behind a pin. To achieve the locked position of the control lever is in the direction of actuation of the control lever Locking hook can be operated to open.

Aus US 2 701 288 A ist eine weitere Schalteranordnung zum Betätigen eines handgehaltene elektrischen Gerätes bekannt. Bei dieser Schaltungsanordnung ist ein Bedienknopf um eine Schwenkachse schwenkbar gelagert. Die Schwenkachse selbst ist in einer Langlochlagerung gehalten. Die Längserstreckung des Langloches verläuft etwa quer zu derjenigen Richtung, mit der der Schaltstößel des Tasters betätigt wird. In dem Bedienknopf ist ein Stellglied angeordnet, das mit einem Fortsatz aus der zum Taster weisenden Seite des Bedienknopfes herausgeführt ist und unterseitig auf der Oberseite des Schaltstößels des Tasters aufliegt. Das diesbezüglich gegenüberliegende Ende des Stellgliedes ist abgekantet und greift in eine Druckfeder ein, über die die auf dem Bedienknopf wirkende Rückstellkraft bereitgestellt wird. Zum Übertragen der Rückstellkraft von der Feder auf den Bedienknopf liegt das Stellglied an der oberseitigen Begrenzung einer Öffnung, durch die der Fortsatz aus dem Bedienelement herausgeführt ist, an. Gehalten ist das Stellglied letztendlich in einer stabilen Stellung durch die auf das eine Ende wirkende Kraft der Feder und die auf das andere Ende wirkende Rückstellkraft des Stellelements des Tasters, so dass das Stellglied in der vorbeschriebenen Anordnung an der oberen Begrenzung der Öffnung des Bedienknopfes anliegt.From US 2 701 288 A a further switch arrangement for actuation is of a hand-held electrical device known. With this circuit arrangement a control button can be swiveled around a swivel axis stored. The swivel axis itself is held in an elongated hole bearing. The longitudinal extension of the elongated hole runs approximately transversely to that Direction in which the switch plunger of the button is operated. By doing Control button is an actuator arranged with an extension from the to the button-facing side of the control button and rests on the underside on the top of the switch plunger of the button. The opposite end of the actuator is folded and engages in a compression spring, via which the one acting on the control button Restoring force is provided. To transfer the restoring force from the spring to the control button the actuator lies on the top Limitation of an opening through which the extension from the control element is brought out. The actuator is ultimately held in one stable position by the force of the spring acting on one end and the restoring force of the actuating element acting on the other end of the button, so that the actuator in the arrangement described above abuts the upper limit of the opening of the control button.

Der Bedienknopf weist zwei Betätigungsoberflächen auf, von denen eine gerillt ist. Femer verfügt der Bedienknopf über einen Stellstift, der an einer Kulisse entlanggeführt wird. Die Kulisse umfasst eine Rastvertiefung, in die der Stift zum Arretieren der geschalteten Stellung dieser Schalteranordnung eingebracht werden kann.The control button has two operating surfaces, one of which is grooved. The control button also has an adjusting pin that is attached to one Scenery is led along. The backdrop includes a recess, in which the pin for locking the switched position of this switch assembly can be introduced.

Zumindest bei einer Betätigung des Bedienknopfes über die gerillte Bedienfläche wird der Stellstift quasi automatisch in die die Schalteranordnung verriegelnde Stellung, in der dieser in die Rastvertiefung eingreift, gebracht. Ist eine solche automatische Verriegelung der Schalteranordnung in der eingeschalteten Stellung des Tasters nicht gewünscht, muss der Bedienknopf an der anderen Bedienoberfläche betätigt werden. At least when the control button is pressed via the grooved control surface the control pin is almost automatically in the switch arrangement locking position, in which this engages in the locking recess. Is such an automatic locking of the switch assembly not desired when the button is switched on, the Control button on the other user interface.

Nachteilig an diesen beiden vorbekannten Ausgestaltungen einer Bedienknopfverriegelung ist, dass eine Verriegelung in der betätigten Bedienknopfstellung durch annähernd dieselbe Bewegung erfolgt wie die eigentliche Tasterbetätigung. Daher besteht die Gefahr, dass der Bedienknopf in seine verriegelte Stellung gebracht wird, ohne dass dieses tatsächlich gewünscht ist. Bei Haarpflegegeräten kann dieses beispielsweise zu einer zu lang andauernden Wärmeeinwirkung führen.A disadvantage of these two previously known configurations of an operating button lock is that a lock in the actuated control button position by approximately the same movement as the actual one The button is activated. There is therefore a risk that the control button in is brought into its locked position without this actually is desired. In the case of hair care devices, for example, this can result in a lead to long-term exposure to heat.

Ausgehend von diesem diskutierten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, ein eingangs genanntes gattungsgemäßes elektrisches Haarpflegegerät dergestalt weiterzubilden, dass eine unbewusste Verriegelung des Bedienknopfes vermieden ist.The invention lies on the basis of this prior art discussed therefore based on the task of a generic electric hair care device to further develop such an unconscious Locking the control button is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Bedienknopf zum Betätigen des Tasters als Ganzes translatorisch gegenüber dem Taster verschiebbar gelagert ist und das Stellglied in der den Taster betätigenden arretierten Stellung des Bedienknopfes zwischen dem Bedienknopf und dem Taster angeordnet ist, wobei durch eine translatorische Verschiebebewegung des Bedienknopfes oder eines diesem zugeordneten Verriegelungsknopfes in einer quer zur Betätigungsrichtung zum Betätigen des Tasters verlaufenden Richtung die Schalteranordnung in ihrer geschalteten Stellung arretierbar ist. This object is achieved in that the control button to actuate the button as a whole, translationally opposite the button is slidably mounted and the actuator in the button actuated locked position of the control button between the control button and the button is arranged, with a translational Sliding movement of the control knob or one of these assigned locking button in a transverse to the direction of actuation the switch arrangement for actuating the push-button direction can be locked in its switched position.

Vorteile einer solchen Schalteranordnung liegen auch darin begründet, daß grundsätzlich lediglich zwei zusätzliche Elemente - das Federelement sowie das Stellglied - benötigt werden, um die erfindungsgemäße Schalteranordnung realisieren zu können.The advantages of such a switch arrangement also lie in the fact that that basically only two additional elements - the spring element and the actuator - are required to the switch assembly according to the invention to be able to realize.

In einer Ausgestaltung der Erfindung ist vorgesehen, daß das Stellglied mit dem Bedienknopf eine gegenständliche Einheit bildet, wobei zwischen dem Stellglied und dem Bedienknopf das Federelement zum Ausüben eines gegen beide Elemente gerichteten Druckes angeordnet ist. Das Stellglied kann sich bei diesem Ausführungsbeispiel mit seiner dem Bedienknopf gegenüberliegenden Seite auf der Oberfläche des Tastergehäuses abstützen und zweckmäßigerweise als Gleitschuh ausgebildet sein, der auf der Tastergehäuseoberfläche gemeinsam mit dem Bedienknopf verschiebbar ist. In der arretierten Stellung des Bedienknopfes befindet sich der Gleitschuh auf dem Taster und hält diesen in seiner betätigten Stellung. Zum Einbringen des Gleitschuhs in diese, den Taster betätigende Stellung kann vorgesehen sein, daß dieser an seiner zum Taster weisenden Kante angefast ist und/oder und daß zunächst eine Tasterbetätigung durch den Bedienknopf selbst erfolgt, bevor der Gleitschuh über den betätigten Taster geschoben wird.In one embodiment of the invention it is provided that the actuator forms a physical unit with the control knob, with between the actuator and the control button the spring element for exercising a pressure directed against both elements is arranged. The In this exemplary embodiment, the actuator can be operated using the control button opposite side on the surface of the push button housing support and expediently designed as a sliding shoe be on the button housing surface together with the control button is movable. The control button is in the locked position the slide shoe on the button and holds it in its actuated Position. To insert the slide shoe into this, the push button Position can be provided that this at its push button facing edge is chamfered and / or and that first a button operation done by the control button itself before the shoe is pushed over the actuated button.

In einem anderen Ausführungsbeispiel ist als Stellglied ein schwenkbar angelenkter Hebel, zweckmäßigerweise ein einarmiger Hebel vorgesehen, auf den der Bedienknopf wirkt und der wiederum zum Betätigen des Tasters vorgesehen ist. Bei diesem Ausführungsbeispiel erfolgt somit in jeder Stellung des Bedienknopfes eine mittelbare Betätigung des Tasters über das Stellglied. Eine Arretierung dieses Bedienknopfes kann beispielsweise durch einen zusätzlichen Verriegelungsknopf herbeigeführt werden, der den Bedienknopf in seiner eingerückten Betätigungsstellung beläßt.In another embodiment, an actuator is pivotable articulated lever, advantageously a one-armed lever is provided, on which the control button acts and which in turn actuates the button is provided. In this embodiment, therefore, occurs in everyone Position of the control button an indirect actuation of the button via the actuator. A locking of this control button can, for example brought about by an additional locking button the control knob in its engaged position leaves.

The button 7 of the microswitch 6 can be compared to the housing 8 of the microswitch 6 also according to the direction of the arrow assigned to the control button actuate.

Der Bedienknopf 4 stützt sich über eine Druckfeder 9 an einem als Steilglied dienenden Gleitschuh 10 ab, der wiederum auf der dem Bedienknopf 4 zugewandten Seite des Gehäuses 8 des Mikroschalters 6 anliegt und auf dieser Seite verschiebbar ist. Figur 2 zeigt die Schalteranordnung 3 in ihrer ungeschalteten Stellung. In dieser Stellung ist der Bedienknopf 4 durch die sich über den Gleitschuh 10 an der Oberfläche des Gehäuses 8 des Mikroschalters 8 abstützenden Druckfeder gehalten. Die Endstellung des Bedienknopfes 4 ist durch entsprechende Vorsprünge des Gehäuses 5 des Haartrockners 1 bestimmt, an denen der Bedienknopf 4 in dieser Stellung anliegt. Zum Betätigen des Bedienknopfes 4 zum Herbeiführen eines Boost-Effektes wird dieser entsprechend der Pfeilrichtung gegen die Kraft der Druckfeder 9 bewegt, so daß eine unterseitig an dem Bedienknopf 4 angeformte Schaltnocke 11 zu dem Taster 7 hingeführt und nach einer Kontaktierung des Tasters 7 diesen betätigt. In dieser geschalteten Stellung ist der Gleitschuh 10 in einer Aussparung 12 innerhalb der Unterseite des Bedienknopfes 4 eingeschoben, so daß die an dem Taster 7 anliegende Seite der Schaltnocke 11 sowie die auf der Oberseite des Gehäuses 8 aufliegende Seite des Gleitschuhs 10 im wesentlichen in einer Ebene angeordnet sind. In dieser geschalteten Stellung ist der Bedienknopf 4 zusammen mit dem Gleitschuh 10 in vertikaler Richtung verschiebbar, so daß die zunächst an der Oberseite des Gehäuses 8 anliegende Fläche des Gleitschuhs 10 nunmehr über den Taster 7 geschoben wird und diesen in seiner geschalteten Stellung hält. Die Kraft der Druckfeder 9 ist ausreichend, damit der Bedienknopf 4 reibschlüssig an der Innenseite der Vorsprünge des Gehäuses 5 fixiert ist, so daß durch diese Maßnahme der Bedienknopf 4 in seiner geschalteten Stellung arretiert ist.The control button 4 is supported by a compression spring 9 as a steep link serving slide shoe 10, which in turn on the control button 4 facing side of the housing 8 of the microswitch 6 and can be moved on this page. Figure 2 shows the switch arrangement 3 in their unswitched position. The control button 4 is in this position through which the sliding block 10 on the surface of the housing 8 of the microswitch 8 supporting compression spring. The end position the control button 4 is through corresponding projections of the housing 5 of the hair dryer 1 determines where the control button 4 in this Position is present. To actuate the control button 4 to bring it about of a boost effect is this according to the direction of the arrow against the Force of the compression spring 9 moves, so that on the underside of the control button 4 molded switching cam 11 led to the button 7 and after a contacting of the button 7 actuates it. In this switched Position is the shoe 10 in a recess 12 within the bottom the control button 4 inserted so that the on the button 7th adjacent side of the switching cam 11 and that on the top of the housing 8 overlying side of the sliding block 10 essentially in one Level are arranged. The control button is in this switched position 4 can be displaced in the vertical direction together with the sliding shoe 10, so that the initially adjacent to the top of the housing 8 Surface of the slide shoe 10 now pushed over the button 7 and keeps it in its switched position. The force of the compression spring 9 is sufficient so that the control button 4 frictionally on the inside the projections of the housing 5 is fixed, so that by this Measure the control button 4 is locked in its switched position.

Es ist zweckmäßig, die vordere untere Kante des Gleitschuhs 10, die zu der Taste 7 des Mikroschalters 6 weist, mit einer Fase zu versehen. Weist der Gleitschuh 10 an seiner zum Taster 7 weisenden Seite eine Auflaufschräge auf, deren Höhe größer ist als die Höhe der Taste 7 abragend von der Oberseite des Gehäuses 8, kann der Bedienknopf 4 auch unmittelbar in seine arretierte Stellung gebracht werden, so daß dieser dann quasi als Schiebeschalter wirkend eingesetzt ist.It is useful to have the front lower edge of the shoe 10 facing the button 7 of the microswitch 6 has a chamfer. has the sliding block 10 has a run-up slope on its side facing the button 7 on, the height of which is greater than the height of the key 7 protruding from the top of the housing 8, the control button 4 can also directly be brought into its locked position, so that it then is effectively used as a slide switch.

Gemäß einem weiteren Ausführungsbeispiel der beanspruchten Erfindung ist in Figur 3 eine weitere Schalteranordnung 13 gezeigt, die ebenfalls für einen Haartrockner zum Bereitstellen eines Boost-Effektes vorgesehen ist. Die Schalteranordnung 13 umfaßt wiederum einen Mikroschalter 14, dessen Taste mit dem Bezugszeichen 15 gekennzeichnet ist. In dem Gehäuse 16 des Haartrockners gelagert ist ein Bedienknopf 17, der in das Gehäuse 16 entsprechend der dargestellten Pfeile eingedrückt werden kann. Der Bedienknopf 17 weist zwei einzelne Arme 18, 19 auf, wobei der Arm 18 als Stößel zum Betätigen eines einarmigen Hebels 20 wirkt . Der Hebel 20 ist durch eine Nocke 21 schwenkbar in dem Gehäuse 16 gehalten und dient zum Betätigen des Tasters 15 des Mikroschalters 14. Der Hebel 20 ist gegen die Kraft einer Druckfeder 22 durch den Bedienknopf 17 zum Betätigen der Taste 15 bewegbar. Zu diesem Zweck ruht das untere Ende des Armes 18 auf der Oberseite des Betätigungsfortsatzes 23 des Hebels 20. Wie auch bei der Schalteranordnung der Figuren 1 und 2 ist die Druckfeder 22 dafür verantwortlich, daß der Bedienknopf 15 in seiner Grundstellung verbleibt.According to a further embodiment of the claimed invention 3 shows a further switch arrangement 13, which is also for a hair dryer is provided to provide a boost effect. The switch arrangement 13 in turn comprises a microswitch 14, the Key is labeled with the reference number 15. In the case 16 of the hair dryer is a control button 17, which is in the housing 16 can be pressed in according to the arrows shown. The control button 17 has two individual arms 18, 19, the arm 18 acts as a plunger for actuating a one-armed lever 20. The lever 20 is pivotally held in the housing 16 by a cam 21 and serves to actuate the button 15 of the microswitch 14. The lever 20 is against the force of a compression spring 22 by the control button 17 Pressing the button 15 movable. For this purpose, the lower end is at rest of the arm 18 on the top of the actuation extension 23 of the lever 20. As with the switch arrangement of Figures 1 and 2 Compression spring 22 responsible for the control button 15 in its Basic position remains.

Die beiden Arme 18, 19 des Bedienknopfes 15 sind Teil eines verschiebbaren Verriegelungsknopfes 24, der, wie durch den weiteren Pfeil dargestellt, bezüglich des Bedienknopfes 17 verschiebbar ist. Das untere Ende des Armes 19 trägt eine Verriegelungsnocke 25, die in der in Figur 1 gezeigten ungeschalteten Nullstellung der Schalteranordnung 13 in einer Durchbrechung des Gehäuses 16 angeordnet ist. Bei einer Betätigung des Bedienknopfes 17 und somit des Verriegelungsknopfes 24 wird die Verriegelungsnocke 25 aus dieser Durchbrechung herausgeführt, so daß anschließend der Verriegelungsknopf 24 gegenüber dem Bedienknopf 17 verschoben werden kann. Die Verriegelungsnocke 25 befindet sich dann hinter einem Steg des Gehäuses 16, so daß in dieser Stellung eine Rückstellung des Bedienknopfes 17 durch die Federkraft der Druckfeder 22 verhindert ist. Folglich ist der Bedienknopf 17 arretiert, während die Taste 15 des Mikroschalters 14 betätigt ist.The two arms 18, 19 of the control button 15 are part of a slidable Locking button 24, which, as shown by the further arrow, is displaceable with respect to the control button 17. The bottom end of the arm 19 carries a locking cam 25, which is shown in FIG unswitched zero position of the switch arrangement 13 in a Breakthrough of the housing 16 is arranged. When actuated the control button 17 and thus the locking button 24 Locking cam 25 led out of this opening, so that then the locking button 24 opposite the operating button 17th can be moved. The locking cam 25 is then located behind a web of the housing 16, so that a provision in this position of the control button 17 by the spring force of the compression spring 22 is prevented. Consequently, the control button 17 is locked while the button 15 of the microswitch 14 is actuated.

Aus der Schnittdarstellung der Schalteranordnung 13 der Figur 4 ist nochmals der Aufbau dieser Schalteranordnung 13 in eingeschalteter Stellung des Bedienknopfes 17 erkennbar.4 is a sectional view of the switch arrangement 13 again the structure of this switch arrangement 13 in the on Position of the control button 17 can be seen.

Figur 5 zeigt diese Schalteranordnung mit betätigtem Bedienknopf 17, jedoch nicht in seiner verriegelten Stellung.FIG. 5 shows this switch arrangement with the operating button 17 actuated, but not in its locked position.

Aus der Beschreibung dieser beiden Ausführungsbeispiele wird deutlich, daß die beanspruchte Schalteranordnung ohne großen Aufwand realisierbar ist, und daß insbesondere die auftretenden Einbautoleranzen durch Einsatz der Druckfeder sowie des als Stellglied vorgesehenen Gleitschuhs 10 bzw. des als Stellglied vorgesehenen Hebels 20 überwunden werden können. Darüber hinaus ermöglicht diese Anordnung, daß der tatsächliche Betätigungshub der Bedienknöpfe 4, 17 größer ist als der tatsächlich vom Mikroschalter 6, 14 bereitgestellte Schalthub. Überdies sind die gezeigten Schalteranordnungen 3, 13 auf einfache Weise in ihrer geschalteten Stellung arretierbar, wobei eine Arretierung nur bewußt und nichtzufällig herbeigeführt werden kann. From the description of these two exemplary embodiments it becomes clear that the claimed switch arrangement can be implemented without great effort and that in particular the installation tolerances that occur Use of the compression spring and the slide shoe provided as an actuator 10 or the lever 20 provided as an actuator can be overcome can. In addition, this arrangement allows the actual Actuation stroke of the control buttons 4, 17 is greater than that actually switching stroke provided by microswitch 6, 14. Moreover, the ones shown are Switch arrangements 3, 13 in a simple manner in their switched Lockable position, locking only consciously and not accidentally can be brought about.
