Description

Die Erfindung betrifft ein linear durch manuelles Drücken entgegen der Kraft einer Feder aus einer ersten stabilen Lage in eine zweite stabile Lage (eingedrückte Lage) und unter der Kraft der Feder zurück verschiebbarer Druckknopf zur Betätigung des schwenkbar gelagerten Kontakthebels eines elektrischen Schaltgerätes gemäß dem Oberbegriff des Anspruches 1.The invention relates to a linear by manual pressing against the force of a spring from a first stable position to a second stable position (depressed position) and under the force of the spring back sliding push button for actuating the pivotally mounted contact lever of an electrical switching device according to the preamble of claim 1.

DE 3 419 834 beschreibt einen ähnlichen Druckknopf.DE 3 419 834 describes a similar push button.

Linear verschiebbare Druckknöpfe sind beispielsweise bei Kugelschreibern bekannt geworden. Dort sind zwei gegeneinander verschiebbare und gegeneinander verdrehbare Fortschaltelemente innerhalb des Kugelschreiberzylinders aufgenommen, die ineinandergreifen und sich berührenden Radialflächen eine Art Stirnverzahnung aufweisen, so daß beim Verdrehen des einen Teiles gegen das andere dasjenige eine Teil, welches die Kugelschreibermine aufnimmt, hin und herbewegt wird. In diesem, sich hin und herbewegenden und drehenden Teil sind axial verlaufende Schlitze vorgesehen, die unterschiedlich lang sind und mit an der Innenfläche der Kugelschreiberhülse angeformten Zähnen in Eingriff gelangen; wenn die Zähne in die axial längeren Schlitze hineingleiten, verschwindet die Kugelschreibermine innerhalb der Hülse und wenn nach Eindrücken des Druckknopfes die Zähne in die kürzeren Schlitze eingreifen, dann ragt die Kugelschreibermine aus der Kugelschreiberhülse hervor, so daß der Kugelschreiber betriebsbereit ist. Linearly displaceable push buttons are known, for example, in ballpoint pens become. There are two mutually displaceable and mutually rotatable Continuous switching elements received within the ballpoint pen cylinder, which interlock and contacting radial surfaces have a kind of spur toothing, so that when turning one part against the other one part, which receives the ballpoint pen refill, is moved back and forth. In this, go out and moving and rotating part axially extending slots are provided, which are different lengths and molded with on the inner surface of the ballpoint pen sleeve Engage teeth; when the teeth in the axially longer slots slide in, the pen refill disappears inside the sleeve and when after pressing the push button, the teeth engage in the shorter slots, then protrudes the ballpoint pen refill from the ballpoint pen sleeve, so that the ballpoint pen is ready for use.

Für manche Anwendungsfälle kann eine solche Anordnung nicht eingesetzt werden.For some applications, such an arrangement can not be used.

Ein Druckknopf der eingangs genannten Art ist aus der FR 2 322 442 bekannt geworden. Die dort beschriebenen Gleitflächenabschnitte, auf denen ein federnder Drahtbügel mit seinem freien, L-förmig abgewinkelten Ende gleitet, sind in einer Ebene angeordnet; die Zuordnung des Drahtbügels zu den Gleitflächenabschnitten ist so gewählt, daß das abgewinkelte Ende beim Drücken des Druckknopfes die zwischen den Gleitflächenabschnitten befindliche Trennwandung umfährt.A push button of the aforementioned type has become known from FR 2 322 442. The Gleitflächenabschnitte described there, on which a springy wire hanger with its free, L-shaped angled end slides are arranged in a plane; the assignment of the wire bracket to the Gleitflächenabschnitten is chosen so that the angled end when pressing the push button between the Gleitflächenabschnitten bypasses located partition wall.

Diese Anordnung ist, da sie bei einem Druckknopf für einen Kleintaster verwendet ist, für viele Anwendungen nicht robust genug.This arrangement is because it is used in a push button for a small button, not robust enough for many applications.

Aufgabe der Erfindung ist es, einen Druckknopf der eingangs genannten Art so auszugestalten, daß eine korrekte Bewegung des Rastelementes um die Trennwandung immer sichergestellt ist und daß dabei auch eine ausreichende Robustheit des Druckknopfes erzielt ist.The object of the invention is to design a push button of the type mentioned above, that a correct movement of the locking element to the partition wall always is ensured and that while also a sufficient robustness of the push button achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Gleitflächen unterschiedliche Abstände von einer Bezugsfläche aufweisen, wobei an der drückflächenabseitigen Verbindungsstelle der Gleitflächen eine dritte Stufe von der einen zur anderen Gleitfläche vorgesehen ist, die verhindert, daß das Rastelement beim Niederdrücken des Druckknopfes in die zweite Gleitfläche gelangt.This object is achieved in that the sliding surfaces different Have distances from a reference surface, wherein at the pressure surface downstream Junction of the sliding surfaces a third step from one to the other Sliding surface is provided, which prevents the locking element during depression of the push button enters the second sliding surface.

Erst durch das Vorsehen der dritten Stufe ist eine sichere Trennung der Gleitflächen voneinander gewährleistet und das Rastelement wird in jedem Falle beim Eindrücken des Druckknopfes wegen der dritten Stufe nicht in die falsche" Gleitfläche hineingelangen können. Demgemäß ist die zweite Gleitfläche zumindest in dem der Drückfläche abgewandten Verbindungsabschnitt zur ersten Gleitfläche bezogen auf diese durch die dritte Stufe erhöht.Only by providing the third stage is a safe separation of the sliding surfaces ensures each other and the locking element is in each case when pressing of the pushbutton, because of the third step, did not get into the wrong sliding surface can. Accordingly, the second sliding surface is at least in that of the pressing surface facing away connecting portion to the first sliding surface based on these by the third level increased.

Gemäß einer weiteren Ausgestaltung befindet sich zwischen der ersten Gleitfläche und dem Gleitflächenabschnitt, der im Bereich des Rastsackes liegt, eine erste Stufe, mit der sicher erreicht wird, daß dann, wenn sich das Rastelement im Rastsack befindet, beim Niederdrücken das Rastelement sich nicht in die erste Gleitfläche bewegen kann.According to another embodiment is located between the first sliding surface and the Gleitflächenabschnitt, which lies in the region of the Racksackes, a first stage, with the sure is achieved that, when the locking element is in the latching bag, when depressing the locking element can not move into the first sliding surface.

Zusätzlich ist zwischen dem Gleitflächenabschnitt im Bereich des Rastsackes und der zweiten Gleitfläche eine zweite Stufe vorgesehen, über die der dem Rastsack benachbarte Gleitflächenabschnitt zur zweiten Gleitfläche abfällt; damit wird ebenfalls sicher erreicht, daß das Rastelement nicht wieder in den Bereich des Rastsackes zurückgelangen kann, wenn der Druckknopf eingedrückt wird.In addition, between the Gleitflächenabschnitt in the region of the locking bag and the second sliding surface provided a second stage, via which the Racksack adjacent Sliding surface portion falls to the second sliding surface; it will also be safe ensures that the locking element does not get back into the area of the locking bag can when the push button is pressed.

Insgesamt können daher drei Stufungen vorgesehen werden, über die das Rastelement bei einem Umlauf um die Trennwandung jeweils von der einen Gleitfläche in den jeweils benachbarten Gleitflächenabschnitt hineinfallen kann, wodurch sichergestellt ist, daß das Rastelement immer im gleichen Umlaufsinn um die Trennwandung herumfährt.Overall, therefore, three stages can be provided, via which the locking element in a circulation around the partition each of the one sliding surface in the each adjacent sliding surface portion can fall into it, thereby ensuring is that the locking element always moves around in the same direction of rotation around the partition wall.

Gemäß einer weiteren Ausführungsform der Erfindung besitzt das Rastelement einen Rasthaltehebel mit einer senkrecht dazu verlaufenden Nase, der um eine Achse, die senkrecht zu den Gleitflächenebenen verläuft, schwenkbar ist, wodurch erreicht wird, daß die Nase auch sicher beim Drücken um die Trennwandung herumlaufen kann. Damit die Nase auf den Gleitflächen bleibt, ist eine erste Feder vorgesehen, die den Rasthaltehebel dauernd in Richtung Gleitflächen drückt. Zusätzlich ist eine zweite Feder vorgesehen, die den Rasthaltehebel um die Achse, die senkrecht zu dem Gleitflächenelement verläuft, in eine Richtung beaufschlagt, so daß ein Umlauf der Nase auf den Gleitflächen um die Trennwandung in jedem Fall sichergestellt ist.According to a further embodiment of the invention, the locking element has a Snap-in lever with a nose extending perpendicularly about an axis, the is perpendicular to the Gleitflächenebenen, is pivotally, which is achieved that the nose can also run around safely when pressing around the partition. So that the nose remains on the sliding surfaces, a first spring is provided, which the Keep holding lever in the direction of sliding surfaces. In addition, a second spring provided, which the latching lever about the axis perpendicular to the Gleitflächenelement runs, applied in one direction, so that a circulation of the nose up the sliding surfaces is ensured around the partition in each case.

Gemäß einer weiteren Ausführungsform ist der Rasthaltehebel an einem drehbar gelagerten Haltezapfen angeformt, der in seiner eigenen Achse gleitend bewegbar ist und auf den die Feder einwirkt, so daß die Nase gegen die Gleitflächen gedrückt ist. Dabei ist der Bewegungsweg des Haltezapfens so bemessen, daß die Nase auch von den Gleitflächen über die Trennwandung abdrückbar ist.According to a further embodiment, the latching lever is mounted on a rotatably mounted Holding pin formed, which is slidably movable in its own axis and on which the spring acts, so that the nose is pressed against the sliding surfaces. there the path of movement of the holding pin is dimensioned so that the nose of the Sliding surfaces on the partition wall can be abdrückbar.

Insbesondere die letztere Lösung findet dann Verwendung, wenn der Druckknopf als Betätigungselement in einem Leitungs- oder Fehlerstromschutzschalter Verwendung finden soll. Dann nämlich muß der Rasthaltehebel bzw. die Rastnase im Falle eines Überstromes oder eines Kurzschlußstromes oder eines Fehlerstromes so bewegt werden, daß sie nicht in den Rastsack hineingelangt; bei einer entsprechend konstruktiven Ausgestaltung kann der Rasthaltehebel bzw. der Haltezapfen von einem Kontakthebel so verschoben werden, daß die Nase über die Trennwandung hinweggleiten kann, was durch die zweite Feder bewirkt wird.In particular, the latter solution is used when the push button as Actuator in a line or residual current circuit breaker use should find. Then that is the Rasthaltehebel or latching lug in the case of Overcurrent or a short-circuit current or a fault current to be moved so that she did not get into the bag; at a correspondingly constructive Design of the latching lever or the retaining pin of a contact lever be moved so that the nose can slide over the partition, what is effected by the second spring.

Ein Druckknopf 10 der Fig. 1 umfaßt einen zylindrischen Abschnitt 11, dessen nicht sichtbare, in der Zeichnung oben liegende Fläche (bei 12) eine Drückfläche aufweist. An der entgegengesetzten Kreisfläche 13 des zylindrischen Abschnittes schließt ein erster Vorsprung 14 und ein zweiter Vorsprung 15 an, der eine etwa rechteckige Form aufweist und auf dem auf einer der Breitseiten eine Gleitflächenanordnung 16 vorgesehen ist. Die Gleitflächenanordnung 16 besitzt eine etwa parallel zur Bewegungsrichtung des Druckknopfes 10 verlaufende erste Gleitfläche 17 und eine parallel dazu verlaufende zweite Gleitfläche 18, die in ihrem drückflächenseitigen Bereich über eine Verbindungsstelle 19 und ebenfalls über eine drückflächenabseitige Verbindungsstelle 20 miteinander verbunden sind. Von einer nicht näher dargestellten Bezugsebene, die parallel zu den Gleitflächen oder angenähert parallel zu den Gleitflächen 17, 18 verläuft, besitzen beide Gleitflächen 17 und 18 unterschiedlichen Abstand: die erste Gleitfläche steigt von der Verbindungsstelle 20 leicht an bis zu einer im Bereich der Verbindungsstelle 19 befindlichen Sattelfläche 21, die zur eigentlichen Verbindungsstelle 19 über eine Stufe 22 abfällt. Über eine weitere Stufe 23 fällt die Verbindungsstelle 19 ab zur zweiten Gleitfläche 18, die bis hin zur Verbindungsstelle 20 bezogen auf diese Bezugsebene ansteigt, so daß an der Verbindungsstelle 20 zwischen der zweiten Gleitfläche und der ersten Gleitfläche eine dritte Stufe 24 vorgesehen ist, über die die zweite Gleitfläche zur ersten Gleitfläche 17 abfällt. Zwischen den Gleitflächen 16 und 17 befindet sich eine Trennwandung 25, die auf der der Verbindungsstelle 19, also der drückflächennahen Verbindungsstelle 19 mit einem Rastsack 26 versehen ist. Wenn eine feststehende und nur quer zu den Gleitflächen 17 und 18 federnd an diese angedrückte Nase auf den Gleitflächen 17 und 18 entlanggleitet, dann gleitet sie zunächst in Pfeilrichtung P1 (Relativbewegung) auf der Gleitfläche 17 nach oben zur Sattelfläche 11 und rutscht von dort über die Stufung 22 auf die Verbindungsstelle 19 und hinter den Rastsack 26, wodurch der Druckknopf 10 in der eingedrückten Stellung festgehalten wird. Die Verbindungsstelle 19 der beiden Gleitflächen 17 und 18 ist nach oben, also zur Drückflächenseite hin, von einer senkrecht dazu verlaufenden Stufung 27 abgeschlossen, die unter einem Winkel von 45° zur Bewegungsrichtung des Druckknopfes verläuft und in die Stufe 22 übergeht, wobei die Stufung 27 oder Grenzwandung 27 parallel zu der der Gleitbahn 18 benachbarten V-Fläche 28 des Rastsackes 26 verläuft. Wenn der Druckknopf 10 weiter hineingedrückt wird, dann verschiebt sich die Rastnase in Pfeilrichtung P2 und wird über die Stufung 27 und die weitere Stufe 23 hin zur zweiten Gleitfläche 18 abgelenkt und gleitet dann, wenn der Druckknopf wieder nach oben gleitet, auf der zweiten Gleitfläche 18 bis hin zur zweiten Verbindungsstelle 20 und schnappt über die Stufe 24 wieder auf die erste Gleitbahn 17. Die Führung der Rastnase erfolgt also durch die Trennwandung 25, die Stufung 27 und eine parallel zur Trennwandung 25 verlaufende Begrenzungswand 29, zwischen denen die zweite Gleitfläche 18 verläuft. Die Begrenzungswand 29 weist im Bereich der Verbindungsstelle 20 einen zur Gleitfläche 17 hin geneigten Bogen 30 auf. Bei der Bewegung P3 wird die Rastnase zwischen der Begrenzungswand 29 mit dem Bogen 30 und der Trennwandung 25 auf der Gleitfläche 18 geführt.A push button 10 of Fig. 1 comprises a cylindrical portion 11 whose non-visible, lying in the drawing surface (at 12) has a pressing surface. On the opposite circular surface 13 of the cylindrical portion includes a first projection 14 and a second projection 15, which has an approximately rectangular shape and on which on one of the broad sides of a sliding surface assembly 16 is provided. The sliding surface arrangement 16 has an approximately parallel to the direction of movement of the push button 10 extending first sliding surface 17 and a parallel thereto extending second sliding surface 18, which are connected in their squeegee side region via a connection point 19 and also via a press surface on the downstream connection point 20. From a reference plane not shown in detail, which runs parallel to the sliding surfaces or approximately parallel to the sliding surfaces 17, 18, both sliding surfaces 17 and 18 have different distances: the first sliding surface rises slightly from the connection point 20 up to one in the region of the connection point 19 located saddle surface 21, which drops to the actual junction 19 via a step 22. Via a further step 23, the connection point 19 drops off to the second sliding surface 18, which rises up to the connection point 20 relative to this reference plane, so that a third step 24 is provided at the connection point 20 between the second sliding surface and the first sliding surface the second sliding surface to the first sliding surface 17 drops. Between the sliding surfaces 16 and 17 is a partition wall 25 which is provided on the connection point 19, so the pressing surface near junction 19 with a latching bag 26. When a fixed and only transversely to the sliding surfaces 17 and 18 resiliently slid on this pressed nose on the sliding surfaces 17 and 18, then it slides first in the direction of arrow P 1 (relative movement) on the sliding surface 17 up to the saddle surface 11 and slips over from there the gradation 22 on the junction 19 and behind the latching bag 26, whereby the push button 10 is held in the depressed position. The junction 19 of the two sliding surfaces 17 and 18 is up, ie to the pressing surface side, completed by a perpendicular thereto gradation 27 which extends at an angle of 45 ° to the direction of the push button and passes into the step 22, wherein the gradation 27th or boundary wall 27 runs parallel to the sliding track 18 adjacent V-surface 28 of the latching bag 26. If the push button 10 is pressed further, then the detent moves in the direction of arrow P 2 and is deflected over the gradation 27 and the further step 23 toward the second sliding surface 18 and then slides when the push button slides back up on the second sliding surface 18 to the second connection point 20 and snaps over the step 24 again on the first slide 17. The guide of the locking lug thus takes place through the partition wall 25, the gradation 27 and a parallel to the partition 25 extending boundary wall 29, between which the second sliding surface 18th runs. The boundary wall 29 has in the region of the connection point 20 to the sliding surface 17 inclined toward arc 30. In the movement P 3 , the latching lug between the boundary wall 29 with the sheet 30 and the partition wall 25 is guided on the sliding surface 18.

Das Rastelement (siehe weiter unten) macht somit eine Bewegung senkrecht zur Bezugsebene und außerdem noch eine Drehbwegung um eine Drehachse, die senkrecht zu der Bezugsebene verläuft. Damit diese Drehbewegung auch in jedem Fall sichergestellt ist, ist eine zweite Feder vorgesehen, deren Federkraft das Rastelement entgegen dem Uhrzeigersinn dreht bzw. beaufschlagt, so daß die Rastnase 34 an der Trennwandung 25 entlang auf der Gleitfläche 17 zum Rastsack 26 und von dort entlang der Begrenzungswand 29 zum Ausgangspunkt an der Verbindungsstelle 20 gleitet (siehe auch Fig. 3).The locking element (see below) thus makes a movement perpendicular to the reference plane and also a Drehbwegung about a rotation axis, the vertical to the reference plane. In order to ensure this rotational movement in any case is, a second spring is provided, the spring force counteracts the locking element Turns clockwise or acted upon, so that the latch 34 on the Partition 25 along on the sliding surface 17 to the latching bag 26 and from there along the boundary wall 29 slides to the starting point at the junction 20 (see also Fig. 3).

An dem ersten Vorsprung 14 schließt ein Arm 31 an, an dem ein senkrecht dazu und senkrecht zur Bewegungsrichtung des Druckknopfes 10 verlaufender Zapfen 32 anschließt (siehe weiter unten). In dem Vorsprung 15 befindet sich eine axial verlaufende Bohrung 33, in der eine Druckfeder angeordnet ist (nicht gezeigt), die den Druckknopf 10 nach oben drückt. Die Eindrückbewegung ist die Bewegung in Pfeilrichtung E und die Ausdrückbewegung ist die Bewegung gemäß Pfeilrichtung A. Die Bewegung E erfolgt manuell und die Bewegung A aufgrund der in der Bohrung 33 befindlichen Druckfeder.At the first projection 14 includes an arm 31, to which a perpendicular thereto and perpendicular to the direction of movement of the push button 10 extending pin 32 connects (see below). In the projection 15 is an axially extending Bore 33, in which a compression spring is arranged (not shown), the push button 10 pushes up. The Eindrückbewegung is the movement in the direction of arrow E and the expression movement is the movement according to arrow direction A. The movement E takes place manually and the movement A due to the located in the bore 33 Spring.

Die Fig. 2 und 3 zeigen den Druckknopf 10 mit der Gleitfläche 17, auf der das Gleitelement 34 bzw. Rastelement 34 entlanggleitet. Dieses Rastelement 34 besitzt eine Nase 35, die an einem etwa parallel zur Bewegungsrichtung des Druckknopfes 10 verlaufenden Arm 36 angeformt ist, der mit einem quer dazu verlaufenden Bolzen 37 verbunden ist; der Bolzen 37 ist in seiner Achsrichtung verschieblich, so daß auch der Arm 36 verschiebbar ist; darüberhinaus ist der Bolzen 37 auch drehbar um seine Längsachse, so daß der Arm 36 um die Bolzenachse 37 verschwenkbar ist.Figs. 2 and 3 show the push button 10 with the sliding surface 17 on which the sliding element 34 and latching element 34 slides along. This locking element 34 has a Nose 35, which is at an approximately parallel to the direction of movement of the push button 10th extending arm 36 is integrally formed with a transverse thereto bolt 37th connected is; the bolt 37 is slidable in its axial direction, so that the Arm 36 is slidable; Moreover, the bolt 37 is also rotatable about his Longitudinal axis, so that the arm 36 is pivotable about the pin axis 37.

Die Fig. 3 zeigt den Rastarm 36 mit der Rastnase 34 an der zweiten Verbindungsstelle 20. Wenn der Druckknopf in Pfeilrichtung E gedrückt wird, dann gleitet, wie aus Fig. 5 ersichtlich ist, die Rastnase des Rastarmes 36 hin zur Verbindungsstelle 19 und schnappt dann, wie aus Fig. 7, 8 und 9 zu sehen ist, in den Rastsack 26; die Fig. 8 und 9 zeigen diese eingedrückte, stabile Lage.3 shows the latching arm 36 with the locking lug 34 at the second connection point 20. When the push button is pushed in the direction of arrow E, then slides as shown in FIG. 5 it can be seen, the latching lug of the latching arm 36 toward the junction 19 and then snaps, as can be seen in FIGS. 7, 8 and 9, into the latching sack 26; Figs. 8 and 9 show this indented, stable position.

Bei der Stellung nach Fig. 11 (unabhängig von der Stellung gemäß Fig. 10) würde die Rastnase 35 auf der zweiten Gleitfläche 18 gleiten, bis sie, wenn der Druckknopf in Pfeilrichtung A bewegt wird, wieder in der Stelle endet, die in der Fig. 3 dargestellt ist. In the position of FIG. 11 (regardless of the position shown in FIG. 10) would Latch 35 on the second sliding surface 18 slide until it, when the push button in Arrow direction A is moved, ends again in the position shown in Fig. 3.

Es ist oben angedeutet worden, daß die Anordnung gemäß Fig. 1 bzw. 2 bis 13 bei einem Leitungsschutzschalter Verwendung findet. Zu diesem Zweck ist gezeigt, daß an einer Drehachse 38 ein Kontakthebel 39 drehbar gelagert ist, der ein bewegliches Kontaktstück 40 aufweist und auf der entgegengesetzten Seite einen Anschlag 41, der gegen die Stirnfläche des Bolzens 37 anliegt.It has been indicated above that the arrangement of FIG. 1 or 2 to 13 at a circuit breaker is used. For this purpose it is shown that a rotary axis 38, a contact lever 39 is rotatably mounted, which is a movable Contact piece 40 has and on the opposite side a stop 41, the abuts against the end face of the bolt 37.

Die Fig. 2 und 3 zeigen die Anordnungen in der Ausschaltstellung, wenn also der Druckknopf 10 vollständig aus dem Schaltgerät herausragt. Die Rastnase 35 befindet sich dabei an der Verbindungsstelle 20. Das bewegliche Kontaktstück ist in seiner Ausschaltstellung. Zum Einschalten wird der Druckknopf 10 in Pfeilrichtung E gedrückt, wodurch über eine in den Fig. nicht näher dargestellte Schaltschloßanordnung, die mit dem Druckknopf in Verbindung steht, der bewegliche Kontakthebel 39 in die Berührungsstellung mit einem festen Kontaktstück 41 gelangt. Das Rastelement 35 befindet sich auf der Gleitfläche 17 aber noch in gewisser Entfernung zur Verbindungsstelle 19. Wenn der Druckknopf 10 weiter hineingedrückt wird, dann wird die Rastnase 35 im Bereich der Verbindungsstelle 19 in den Rastsack 26 einschnappen; man erkennt in Fig. 6, daß der Druckknopf weiter hineingedrückt ist, als es nötig wäre zum Verrasten, weil ein Abstand d zwischen dem Grund des Rastsackes 26 und der Nase 35 vorhanden ist; wenn der Druckknopf 10 freigegeben wird, dann bewegt sich der Druckknopf 10 kurz in Pfeilrichtung A und der Grund des Rastsackes 26 legt sich gegen die Rastnase 35 an. Dies ist dann die Einschaltstellung.Figs. 2 and 3 show the arrangements in the off position, so if the Push button 10 protrudes completely from the switching device. The latch 35 is located itself at the junction 20. The movable contact piece is in his Off position. To turn on the push button 10 is pressed in the direction of arrow E, whereby a not shown in the figures switching mechanism arrangement, with the push button is in communication, the movable contact lever 39 in the contact position with a fixed contact piece 41 passes. The locking element 35 is located on the sliding surface 17 but still at a certain distance to the junction 19th If the push button 10 is pressed further, then the latch 35 is in the area the connection point 19 snap into the locking bag 26; one recognizes in Fig. 6 that the push button is pushed further in, as it would be necessary for locking, because a distance d exists between the bottom of the latching bag 26 and the nose 35; when the push button 10 is released, then the push button 10 moves in briefly Arrow direction A and the reason of the latching bag 26 abuts against the latching lug 35. This is then the switch-on position.

Wenn der Schalter ausgelöst hat, d. h. wenn ein elektromagnetischer oder thermischer Auslöser des Leitungsschutzschalters angesprochen hat, dann wird durch Entklinkung eines nicht näher dargestellten Schaltschlosses der Kontakthebel 39 in Ausschaltstellung gelangen, wobei der Anschlag 41 den Bolzen 37 in der Zeichnung Fig. 10 nach links verschiebt, so daß die Rastnase 35 entgegen der Kraft einer nicht gezeichneten ersten Feder frei von der Gleitfläche 18 kommt. Dadurch kann der Druckknopf 10 aufgrund der Kraft der nicht gezeigten Druckfeder in Pfeilrichtung A wegwandern. Man erkennt in der Fig. 10, daß die Begrenzungswand 29 so gewählt ist, daß selbst bei der maximalen Verschiebung des Rastelementes 34 weg von der Gleitfläche 18 sich die Rastnase 35 immer noch im Bereich der Begrenzungswand 29 befindet. If the switch has triggered, d. H. if an electromagnetic or thermal Trigger of the circuit breaker has addressed, then by unlatching a switching lock, not shown, the contact lever 39 in the off position reach, wherein the stop 41, the bolt 37 in the drawing Fig. 10 after shifted left, so that the locking lug 35 against the force of a not shown first spring comes free from the sliding surface 18. As a result, the push button 10 due walk away the force of the compression spring, not shown, in the direction of arrow A. you recognizes in Fig. 10, that the boundary wall 29 is chosen so that even in the maximum displacement of the locking element 34 away from the sliding surface 18 is the Latch 35 is still located in the region of the boundary wall 29.

Bei einem elektrischen Leitungsschutzschalter ist von wichtiger Bedeutung, daß auch beim Einschaltvorgang eine Auslösung erfolgen kann. Das Rastelement muß im Falle eines Kurzschlußstromes so bewegt werden, daß es in eingedrücktem Zustand des Druckknopfes nicht in den Rastsack 26 gelangen kann; hierbei wird es von dem Kontakthebel 39 über den Vorsprung 41 nach links bewegt und gleitet so über die Trennwandung, siehe Fig. 12 und 13. Wie oben angedeutet ist für alle diese Bewegungsabläufe auch die zweite Feder, die als Drehfeder eine Drehkraft F auf das Rastelement ausübt, von wesentlicher Bedeutung.When an electrical circuit breaker is important, that too can be triggered during the switch-on. The locking element must in case a short-circuit current are moved so that it is in the depressed state of the Push button can not get into the Rastsack 26; Here it is from the contact lever 39 moves over the projection 41 to the left and thus slides over the partition, see Figs. 12 and 13. As indicated above, for all these movements Also, the second spring, the rotational spring as a rotational force F on the locking element is essential.
