Abstract

Proposed is an auxiliary switch for fitting to protective circuit breakers, the switch having two moving electric contacts (35, 36) each of which works in conjunction with two fixed electric contacts (31, 32, 33, 34). The moving contacts (35, 36) are actuated by a signal lever (5) and a contact lever (4), an actuator knob (3) being connected to the contact lever (4), an actuator knob (3) being connected to the contact lever (4) via an elbow lever (7, 11). The actuator knob (3) can be connected to that of the circuit breaker. A catch holder (6), which can be connected to the switch mechanism of the circuit breaker, acts to trigger the signal lever (5) and/or the contact lever (4). One arm of the elbow lever (7, 11) is formed by a catch (7) which engages with the catch holder (6) when the switch is "on". A locking device (8), which is designed to prevent the signal lever (5) from moving when the switch is triggered by the actuator knob (3) [the signal lever (5) has a click-in projection (50) with which a matching click-in projection (51) on the locking device (8) engages], is mounted (49) on the housing (1) and moved by the elbow lever (7, 11) out of the position in which it prevents the signal lever (5) from being released when the switch is triggered by the circuit breaker via the catch holder (6). The locking device (8) has a control lever (62) working in conjunction with a control device (eccentric shaft) (10) which is mounted in the housing (1, 2) and which fixes the locking device (8) in a position in which it cannot engage with the signal lever (5).

Description

Die Erfindung betrifft einen Zusatzschalter zum Anbau an elektrische Schutzschalter mit zwei beweglichen, elektrischen Kontakten, denen jeweils zwei ortsfeste, elektrische Kontakte zugeordnet sind, mit einem Signalhebel und einem Kontakthebel, welche die beweglichen Kontakte bewegen, mit einem Betätigungsknopf, der mit dem Betätigungsknopf des Schutzschalters verbindbar ist und der den Signalhebel und den Kontakthebel betätigt, mit einer Klinkenauflage, die mit dem Schaltmechanismus des Schutzschalters verbindbar ist, zum Auslösen des Signalhebels und/oder des Kontakthebels, mit einer Sperre, welche die Bewegung des Signalhebels verhindern kann, wenn der Zusatzschalter über den Betätigungsknopf ausgelöst wird, wobei der Betätigungsknopf über einen Kniehebel mit dem Kontakthebel verbunden ist, und wobei ein Arm des Kniehebels von einer Klinke gebildet wird, die im eingeschalteten Zustand des Zusatzschalters mit der Klinkenauflage verhakt.The invention relates to an additional switch for mounting on electrical Circuit breaker with two movable, electrical Contacts, each of which has two fixed, electrical contacts are assigned, with a signal lever and a contact lever, which move the moving contacts with one Actuation button that corresponds to the actuation button of the circuit breaker is connectable and the signal lever and the contact lever actuated, with a jack rest, which with the Switching mechanism of the circuit breaker is connectable to Trigger the signal lever and / or the contact lever with a lock that prevents movement of the signal lever can, if the additional switch is triggered via the operating button is, the operating button with a toggle lever is connected to the contact lever, and wherein an arm of the toggle lever is formed by a jack, which is switched on State of the additional switch hooked with the jack support.

Ein derartiger Zusatzschalter ist aus der EP-A 394 144 bekannt. Nachteilig bei diesem Zusatzschalter ist, daß die Signalfunktion, d.h. der Signalhebel nicht außer Betrieb gesetzt werden kann, wenn dies gewünscht ist.Such an additional switch is known from EP-A 394 144. The disadvantage of this additional switch is that the signal function, i.e. the signal lever is not deactivated can be, if desired.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen gattungsgemäßen Zusatzschalter zur Verfügung zu stellen, bei dem die Signal funktion wahlweise zu- und weggeschaltet werden kann.The present invention is therefore based on the object to provide a generic additional switch, where the signal function can be switched on and off can be.

Gelöst wird diese Aufgabe dadurch, daß die Sperre am Gehäuse gelagert ist und daß die Sperre vom Kniehebel aus der die Auslösung des Signalhebels verhindernden Stellung bewegbar ist, wenn der Zusatzschalter vom Schutzschalter über die Klinkenauflage betätigt wird.This problem is solved in that the lock on the housing is stored and that the lock from the toggle lever from the Triggering of the signal lever preventing position movable is when the additional switch from the circuit breaker over the jack support is operated.

Anders als beim Zusatzschalter gemäß der EP-A 394 144, bei dem die Sperre fest mit dem Signalhebel verbunden und somit immer in Funktion ist, ist gemäß der Erfindung eine gesondert im Gehäuse gelagerte Sperre vorgesehen, die funktionell mit dem Kniehebel zusammenwirkt und von diesem aus der Sperrstellung für den Signalhebel bewegt wird, wenn der Schutzschalter aufgrund einer Fehlerbedingung anspricht und über die Klinkenauflage den Zusatzschalter auslöst.Unlike the additional switch according to EP-A 394 144, in which the lock is firmly connected to the signal lever and therefore always is in function, according to the invention is a separate in Locked housing provided that is functional with the Knee lever interacts and from this from the locked position for the signal lever is moved when the circuit breaker due responds to an error condition and via the jack support triggers the additional switch.

Da als Sperre ein gesondert am Gehäuse gelagerter Teil vorgesehen ist, kann in einer Ausführungsform der Erfindung eine Möglichkeit vorgesehen sein, die Sperre außer Funktion zu setzen, so daß der Signalhebel in jedem Betriebszustand immer gleichzeitig mit dem Kontakthebel bewegt wird.Since a separately mounted part on the housing is provided as a lock is in one embodiment of the invention Possibility to lock the lock out of function set so that the signal lever is always in any operating state is moved simultaneously with the contact lever.

Dies kann gemäß einer bevorzugten Ausführungsform der Erfindung dadurch erfolgen, daß die Sperre einen Stellhebel aufweist, dem eine gehäusefeste Stelleinrichtung zugeordnet ist, über welche die Sperre in einer Stellung festgelegt werden kann, in der sie nicht mit dem Signalhebel verrasten kann.This can be done according to a preferred embodiment of the invention in that the lock has an adjusting lever, which is assigned an actuator fixed to the housing, via which the lock is set in a position in which it cannot lock with the signal lever.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den übrigen Unteransprüchen und der nachfolgenden Beschreibung von Ausführungsformen der Erfindung unter Bezugnahme auf die Zeichnungen.Further features and advantages of the invention result from the remaining subclaims and the description below of embodiments of the invention with reference to the Drawings.

    Zur Verbindung mit elektrischen Anzeigeeinrichtungen weist der Zusatzschalter ein Paar mit je drei Anschlußklemmen 25, 26, 27 und 28, 29, 30 auf, wobei die Anschlußklemmen 25, 26 und 28, 29 mit gehäusefesten Kontakten 31, 32 und 33, 34 elektrisch verbunden sind. Die Klemmen 27 und 30 sind mit beweglichen Kontakten 35 und 36 elektrisch verbunden.For connection to electrical display devices, the Additional switches a pair with three terminals 25, 26, 27 and 28, 29, 30, with the connecting terminals 25, 26 and 28, 29 with contacts 31, 32 and 33, 34 fixed to the housing are connected. The terminals 27 and 30 are movable Contacts 35 and 36 electrically connected.

    Der Schaltmechanismus des Zusatzschalters weist einen Signalhebel 5 und einen Kontakthebel 4 auf, die an einer gemeinsamen Achse 36 im Gehäuse gelagert sind. Auf der gleichen Achse 36 und zwischen dem Signalhebel 5 und dem Kontakthebel 4 ist eine Klinkenauflage 6 gelagert, die über einen Bolzen 21 oder 21' mit dem Schaltmechanismus des elektrischen Schutzschalters verbunden werden kann. Je nachdem, ob der Zusatzschalter an der linken oder rechten Seite des Schutzschalters angeordnet werden soll, wird der nicht benötigte Bolzen 21 oder 21' an der gegenüberliegenden Seite entfernt. The switching mechanism of the additional switch has a signal lever 5 and a contact lever 4 on a common Axis 36 are mounted in the housing. On the same axis 36 and between the signal lever 5 and the contact lever 4 is one Pawl support 6, which is supported by a bolt 21 or 21 ' with the switching mechanism of the electrical circuit breaker can be connected. Depending on whether the additional switch is on the left or right side of the circuit breaker should be, the unneeded bolt 21 or 21 'on the opposite side.

    Der Kontakthebel 4 ist über einen Kniehebel bestehend aus einer Klinke 7 und einem Bügel 11 mit einem Betätigungsknopf 3 verbunden, der wiederum über einen Knopfbolzen 22 mit dem Betätigungsknopf des Schutzschalters verbunden werden kann. Die Klinke 7 ist einerseits mit dem Bügel 11 und anderseits mit dem Kontakthebel 4 über ein Gelenk 12 verbunden (Fig. 5). Dem Betätigungsknopf 3 ist weiters eine Knopffeder 17 zugeordnet, die sich mit einem Schenkel über eine Prüftaste 9 an der Unterschale 1 und mit dem anderen Schenkel am Betätigungsknopf 3 abstützt und diesen im Gegenuhrzeigersinn, d.h. in die AUS-Stellung, belastet, die z.B. in Fig. 1 dargestellt ist. In Fig. 5 ist eine im wesentlichen der Fig. 1 entsprechenden Ausführungsform des Zusatzschalters dargestellt, bei dem der Signalhebel 5 in der abgenommenen Stellung dargestellt ist und die den Zusatzschalter in der EIN-Stellung zeigt.The contact lever 4 is composed of a toggle lever Pawl 7 and a bracket 11 connected to an actuating button 3, which in turn has a button pin 22 with the actuating button of the circuit breaker can be connected. The Jack 7 is on the one hand with the bracket 11 and on the other hand with the contact lever 4 connected via a joint 12 (Fig. 5). The Actuating button 3 is also assigned a button spring 17, the one leg with a test button 9 on the lower shell 1 and with the other leg on the operating button 3 supports and this counterclockwise, i.e. into the exhibition, which e.g. is shown in Fig. 1. In FIG. 5 is essentially the same as FIG. 1 Embodiment of the additional switch shown, in which the Signal lever 5 is shown in the removed position and which shows the additional switch in the ON position.

    In dieser Stellung ist die Klinkenauflage 6, die von einer Auflagefeder 18 im Gegenuhrzeigersinn belastet wird, mit der Klinke 7 verhakt und verhindert, daß der Kniehebel bestehend aus Klinke 7 und Bügel 11 unter der Belastung einer Zugfeder 16, die mit einem Ende 37 an einem Gehäusevorsprung 38 und mit ihrem anderen Ende 39 an einem Ansatz 40 am Kontakthebel 4 angreift, nach außen bzw. oben ausknickt.In this position, the pawl support 6, the one Support spring 18 is loaded counterclockwise, with the Pawl 7 hooks and prevents the knee lever from existing from pawl 7 and bracket 11 under the load of a tension spring 16, which has an end 37 on a housing projection 38 and its other end 39 on a shoulder 40 on the contact lever 4 attacks, buckles outwards or upwards.

    An der Klinkenauflage 6 ist ein Vorsprung 41 mit zwei Bohrungen 42 und 43 vorgesehen, wobei in eine dieser Bohrungen 42, 43 der passende Bolzen 21, 21' zur Verbindung mit dem jeweiligen Schutzschalter eingesteckt ist. Der Bolzen 21 oder 21' ragt dann durch kreissegmentartige Schlitze 44 im Träger 4 oder 45 im Signalhebel 5 und durch entsprechende Schlitze in der Oberschale 2 oder der Unterschale 1 nach außen und durch entsprechende Ausnehmungen in den Schutzschalter und ist dort mit dessen Schaltmechanismus verbunden.On the pawl support 6 is a projection 41 with two holes 42 and 43 are provided, one of these bores 42, 43 the matching bolt 21, 21 'for connection to the respective Circuit breaker is plugged in. The bolt 21 or 21 ' then protrudes through slit 44-like slits in the carrier 4 or 45 in signal lever 5 and through corresponding slots in the upper shell 2 or the lower shell 1 to the outside and through corresponding recesses in the circuit breaker and is there connected to its switching mechanism.

    Wird der Schutzschalter durch eine elektrische Fehlerbedingung ausgelöst, so wird die Bewegung seines Schaltmechanismus über den Bolzen 21 oder 21' auf die Klinkenauflage 6 übertragen, wodurch diese gegen den Uhrzeigersinn verschwenkt und die Rastverbindung mit der Klinke 7 gelöst wird, wodurch der Kniehebel 7, 11 ausknickt und der Kontakthebel 4 unter der Wirkung der Zugfeder 16 im Uhrzeigersinn verschwenkt.The circuit breaker is caused by an electrical fault condition triggered, the movement of its switching mechanism is over transfer the bolt 21 or 21 'to the jack support 6, which pivots this counterclockwise and the Detent connection with the pawl 7 is released, causing the toggle lever 7, 11 buckles and the contact lever 4 under the effect the tension spring 16 is pivoted clockwise.

    Damit beim Einschalten des Zusatzschalters, d.h. beim Bewegen des Betätigungsknopfes 3 von der in Fig. 1 dargestellten Stellung in die in Fig. 4 oder 5 dargestellte Stellung, des Signalhebels ebenso wie der Kontakthebel 4 gegen den Uhrzeigersinn verschwenkt wird, weist der Kontakthebel 4 einen Ansatz 46 und der Signalhebel 5 eine Nase 47 auf, die beim Verschwenken des Kontakthebels 4 gegen den Uhrzeigersinn in Anlage aneinander kommen, wodurch der Signalhebel 5 vom Kontakthebel 4 mitgenommen wird und dabei eine Zugfeder 16' zwischen dem Signalhebel 5 und der Unterschale 1 vorgespannt wird.So that when the additional switch is switched on, i.e. when moving of the operating button 3 from the position shown in Fig. 1 in the position shown in Fig. 4 or 5, the signal lever as well as the contact lever 4 counterclockwise is pivoted, the contact lever 4 has an approach 46 and the signal lever 5 on a nose 47, which when pivoting of the contact lever 4 counterclockwise in the system come together, causing the signal lever 5 from the contact lever 4 is taken along and a tension spring 16 'between the Signal lever 5 and the lower shell 1 is biased.

    Am Signalhebel 5 ist ein Rastvorsprung 50 angeordnet, der mit dem Rastvorsprung 51 einer Sperre 8 zusammenwirkt, d.h. mit ihr verhakt, wenn der Signalhebel 5 seine EIN-Stellung eingenommen hat (siehe Fig. 4). Die Sperre 8 ist an einem gehäusefesten Lager 49 schwenkbar gelagert und von einer Druckfeder 19 zwischen einem Stellhebel 62 der Sperre 8 und einer gehäusefesten Aufnahme 53 gegen den Uhrzeigersinn vorgespannt.On the signal lever 5, a locking projection 50 is arranged, which with the locking projection 51 of a lock 8 cooperates, i.e. With you hooked when the signal lever 5 is in its ON position has (see Fig. 4). The lock 8 is on a housing-fixed Bearing 49 pivoted and by a compression spring 19 between an actuating lever 62 of the lock 8 and one fixed to the housing Prestressed receptacle 53 counterclockwise.

    Die Sperre 8 weist schließlich noch einen Auslösehebelarm 54 auf, der an seinem Ende eine Abwinkelung 55 aufweist, die mit dem Kniehebel bestehend aus Klinke 7 und Bügel 11 zusammenwirkt, wie z.B. in Fig. 4 und 5 ersichtlich ist.The lock 8 finally also has a trigger lever arm 54 on, which has a bend 55 at its end, which with the toggle lever consisting of pawl 7 and bracket 11 cooperates, such as. 4 and 5 can be seen.

    Wird nachdem der Schutzschalter und der Zusatzschalter in die in Fig. 4 gezeigte EIN-Stellung gebracht wurden, der Schutzschalter wie vorhin beschrieben "elektrisch", d.h. durch eine Fehlerbedingung im vom Schutzschalter zu schützenden Stromkreis ausgelöst, so betätigt dessen Schaltmechanismus die Klinkenauflage 6 gegen den Uhrzeigersinn, wodurch der Kniehebel 7, 11 nach oben ausknickt und die Sperre 8 über den Ansatz 55 am Hebel 54 im Uhrzeigersinn verdreht, so daß sich die Rastverbindung 50, 51 zwischen Sperre 8 und Signalhebel 5 löst, noch bevor sich der Signalhebel 5 um einen nennenswerten Betrag gemeinsam mit dem Kontakthebel 4 verdrehen kann. Nachdem die Rastverbindung 50, 51 gelöst wurde, können sowohl der Kontakthebel 4 als auch der Signalhebel 5 im Uhrzeigersinn frei nach rechts verschwenken. After the circuit breaker and the additional switch in the 4, the circuit breaker as previously described "electrical", i.e. by a Fault condition in the circuit to be protected by the circuit breaker triggered, its switching mechanism actuates the Jack support 6 counterclockwise, which causes the knee lever 7, 11 bends upwards and the lock 8 over the neck 55 rotated clockwise on lever 54 so that the Locking connection 50, 51 between lock 8 and signal lever 5 triggers even before the signal lever 5 by a significant amount Can twist amount together with the contact lever 4. After this the locking connection 50, 51 has been released, both the Contact lever 4 and the signal lever 5 clockwise swivel freely to the right.

    Werden hingegen der Schutzschalter und der Zusatzschalter über den Betätigungsknopf 3 manuell ausgeschaltet, wird die Sperre 8 nicht vom Kniehebel 7, 11 ausgelenkt, so daß sich die Rastverbindung 50, 51 zwischen Signalhebel 5 und Sperre 8 nicht löst und sich der Signalhebel 5 nicht verschwenken kann, wogegen der Kontakthebel 4 im Uhrzeigersinn nach rechts verschwenken kann.However, the circuit breaker and the additional switch are over the actuation button 3 manually switched off, the lock 8 not deflected by the toggle lever 7, 11, so that the latching connection 50, 51 between signal lever 5 and lock 8 not loosens and the signal lever 5 cannot pivot, whereas turn the contact lever 4 clockwise to the right can.

    Um die soeben beschriebenen beiden Auslösemöglichkeiten in entsprechende elektrische Signale umzusetzen, sind die festen Kontakte 31, 32 und der ihnen zugeordnete, bewegliche Kontakt 35 sowie die festen Kontakte 33, 34 und der ihnen zugeordnete bewegliche Kontakt 36 vorgesehen. Die beweglichen Kontakte 35, 36 sind an den Enden von zwei Blattfedern 56 und 57 vorgesehen, deren andere Enden über Kontaktwinkel 58, 59 fest mit dem Gehäuse 1, 2 verbunden sind.To the two trigger options just described in Implementing appropriate electrical signals are the fixed ones Contacts 31, 32 and the associated movable contact 35 and the fixed contacts 33, 34 and the associated movable contact 36 is provided. The movable contacts 35, 36 are provided at the ends of two leaf springs 56 and 57, the other ends of which are fixed to the contact angle 58, 59 Housing 1, 2 are connected.

    Auf die Blattfeder 56 wirkt der Kontakthebel 4 und auf die Blattfeder 57 wirkt der Signalhebel 5 in der Art, daß die Blattfeder 56 vom Kontakthebel 4 in der AUS-Stellung gegen den festen Kontakt 33 und in der EIN-Stellung gegen den festen Kontakt 34 gedrückt wird und daß der bewegliche Kontakt 35 vom Signalhebel 5 in der EIN-Stellung gegen den festen Kontakt 32 und in der AUS-Stellung gegen den festen Kontakt 31 gedrückt wird.The contact lever 4 acts on the leaf spring 56 and on the Leaf spring 57 acts on the signal lever 5 in such a way that the Leaf spring 56 from the contact lever 4 in the OFF position against the fixed contact 33 and in the ON position against the fixed Contact 34 is pressed and that the movable contact 35 from Signal lever 5 in the ON position against the fixed contact 32 and pressed against the fixed contact 31 in the OFF position becomes.

    Dazu ist die Blattfeder 56 am Kontakthebel 4 zwischen zwei Ansätzen 58 und 59 und die Blattfeder 57 am Signalhebel 5 zwischen Ansätzen 60 und 61 aufgenommen.For this purpose, the leaf spring 56 on the contact lever 4 is between two Lugs 58 and 59 and the leaf spring 57 on the signal lever 5 added between approaches 60 and 61.

    Wie in Fig. 1 ersichtlich ist, liegen die beweglichen Kontakte 35, 36 in der elektrischen AUS-Stellung, d.h. wenn sie durch eine elektrische Fehlerbedingung durch den Schutzschalter betätigt wurden, an den beiden linken, gehäusefesten Kontakten 31 und 33 an, wogegen in der manuellen AUS-Stellung gemäß Fig. 3 der bewegliche Kontakt 35 (des Signalhebels 5) am rechten gehäusefesten Kontakt 32 und der bewegliche Kontakt 36 (des Kontakthebels 4) am linken gehäusefesten Kontakt 33 anliegt. In der EIN-Stellung (Fig. 3) liegen beide beweglichen Kontakte 35, 36 an ihren zugeordneten, rechten gehäusefesten Kontakten 32, 34 an. Auf diese Weise ist auf einfache Art möglich, durch eine entsprechende Schaltung der Kontakte 31 bis 36, d.h. über die ihnen zugeordneten Anschlußklemmen 25 bis 30, den jeweiligen Schaltungszustand des Schutzschalters bzw. die Ursache für dessen Ausschalten festzustellen.As can be seen in Fig. 1, the movable contacts are 35, 36 in the electrical OFF position, i.e. when through an electrical fault condition caused by the circuit breaker were actuated on the two contacts on the left, fixed to the housing 31 and 33, whereas in the manual OFF position according to Fig. 3 the movable contact 35 (the signal lever 5) on the right Fixed contact 32 and the movable contact 36 (des Contact lever 4) on the left fixed contact 33. Both movable contacts are in the ON position (FIG. 3) 35, 36 on their assigned, right housing-fixed contacts 32, 34. In this way, is possible in a simple way a corresponding switching of contacts 31 to 36, i.e. about the associated terminals 25 to 30, the respective Circuit status of the circuit breaker or the cause of determine its switching off.

    In einigen Fällen ist es jedoch erwünscht, daß die Sperre 8 gänzlich außer Funktion gesetzt wird, d.h., daß der Signalhebel 5 immer, d.h. unabhängig von der Art der Auslösung, entsprechend dem Kontakthebel 4 bewegt wird.In some cases, however, it is desirable that the lock 8 is completely deactivated, i.e. the signal lever 5 always, i.e. regardless of the type of triggering, accordingly the contact lever 4 is moved.

    Dies kann gemäß der Erfindung dadurch bewerkstelligt werden, daß die Sperre 8 in ihrer in Uhrzeigersinn verdrehten Stellung, in der sie nicht mit dem Signalhebel 5 verrasten kann, festgelegt wird. Dazu ist dem Stellhebel 62 der Sperre 8 im Gehäuse eine Exzenterwelle 10 zugeordnet, die in der in den Abbildungen dargestellten Stellung die Bewegung der Sperre 8 gegen den Uhrzeigersinn nicht behindert. Wird die Exzenterwelle 63 jedoch um wenigstens 90° gedreht, wie in Fig. 5 strichliert dargestellt ist, so verdreht sie die Sperre 8 über deren Stellhebel 62 so weit, daß diese nicht mehr mit dem Signalhebel 5 verrasten kann, wodurch die Sperre 8 auf einfache Weise außer Funktion gesetzt wird. Zum Verstellen der Exzenterwelle 10 weist diese einen Schlitz 66 für z.B. einen Schraubenzieher auf.According to the invention, this can be accomplished by that the lock 8 in its clockwise rotated position, in which it cannot lock with the signal lever 5, is set. For this purpose, the control lever 62 of the lock 8 in Housing assigned an eccentric shaft 10 in the in the Figures shown position the movement of the lock 8 not obstructed counterclockwise. Will the eccentric shaft 63, however, rotated by at least 90 °, as in FIG. 5 is shown in dashed lines, it rotates the lock 8 over whose adjusting lever 62 so far that it no longer with the Signal lever 5 can latch, making the lock 8 easy Way is disabled. To adjust the Eccentric shaft 10 has a slot 66 for e.g. one Screwdriver on.

    Am Signalhebel 5 ist weiters ein Signalarm 64 angeordnet, der in den Bereich einer Öffnung 65 an der Oberseite der Unterschale 1 gelangt, wenn der Signalhebel in der AUS-Stellung liegt, so daß direkt am Zusatzschalter eine einfache optische Kontrolle gegeben ist, ob eine elektrische oder manuelle Auslösung vorliegt.A signal arm 64 is also arranged on the signal lever 5 in the area of an opening 65 at the top of the lower shell 1 arrives when the signal lever is in the OFF position lies, so that a simple optical directly at the additional switch Control is given, whether an electrical or manual release is present.

    In der Unterschale 1 ist im Bereich neben dem Betätigungsknopf 3 eine Prüftaste 9 angeordnet, die von der Knopffeder 17 nach außen belastet wird und die die Klinkenauflage 6 über deren Fortsatz 52 betätigt, d.h. im Uhrzeigersinn verschwenkt und somit den Kniehebel 7, 11 freigibt, wenn sie nach innen bzw. unten gedrückt wird. In the lower shell 1 is in the area next to the actuation button 3 a test button 9 arranged by the button spring 17 after is loaded outside and the pawl support 6 over their Extension 52 actuated, i.e. swiveled clockwise and thus releases the toggle lever 7, 11 when it is turned inwards or is pressed down.

    Wie in den einzelnen Zeichnungen dargestellt ist, können die Blattfedern 56, 57 mit den beweglichen Kontakten 35 und 36 verschiedene Formen aufweisen.As shown in the individual drawings, the Leaf springs 56, 57 with the movable contacts 35 and 36 have different shapes.

    Ein Problem bei Schutzschaltern bzw. den ihnen zugeordneten Zusatzschaltern ist, daß sich die Schalter den größten Teil ihrer Einsatzzeit in der EIN- bzw. AUS-Stellung befinden, so daß die offenen Kontakte oxydieren und somit einen erhöhten Widerstand beim Schließen aufweisen. In einer Ausführungsform der Erfindung ist daher vorgesehen, daß, nachdem die beweglichen Kontakte 35, 36 an den Blattfedern 56, 57 vom Kontakthebel 4 und vom Signalhebel 5 so weit bewegt wurden, daß sie an den ortsfesten Kontakten 31, 33 anliegen, der Signalhebel 5 und der Kontakthebel 4 noch ein Stück, etwa 1° bis 5°, vorzugsweise etwa 2° bis 3°, weiterverschwenkt werden, wodurch die Blattfeder 56 etwas gestreckt und Blattfeder 57 etwas weiter durchgebogen wird. Dadurch kommt es zu einer Relativbewegung, d.h. Reibbewegung, zwischen den beweglichen Kontakten 35, 36 und den gehäusefesten Kontakten 32, 34. Entsprechendes kann auch bei den gegenüberliegenden gehäusefesten Kontakten 31, 33, d.h. den Kontakten der jeweiligen AUS-Stellung, vorgesehen sein. Durch diese Relativbewegung wird eine verminderte Kontaktierung durch Oxydieren hintangehalten.A problem with circuit breakers or the ones assigned to them Auxiliary switches is that the switches are the largest part their operating time in the ON or OFF position, so that the open contacts oxidize and thus an increased Have resistance when closing. In one embodiment the invention is therefore provided that after the movable Contacts 35, 36 on the leaf springs 56, 57 from the contact lever 4 and the signal lever 5 were moved so far that they rest on the fixed contacts 31, 33, the signal lever 5 and the contact lever 4 a little more, about 1 ° to 5 °, preferably be pivoted about 2 ° to 3 °, whereby the leaf spring 56 somewhat stretched and the leaf spring 57 somewhat is further bent. This leads to a relative movement, i.e. Frictional movement, between the moving contacts 35, 36 and the contacts 32, 34 fixed to the housing can also be used with the contacts fixed to the housing 31, 33, i.e. the contacts of the respective OFF position be. This relative movement reduces one Keep contacting by oxidizing.

    Zusammenfassend kann die Erfindung beispielsweise wie folgt dargestellt werden:In summary, the invention can be as follows, for example being represented:
