Aus der DE 42 01 026 A1 ist ein Trennschalter mit veränderlicher Handbetätigung bekannt, bei dem zur Veränderung der Betätigungsart sowohl das Schaltschloß als auch die Betätigungswelle zu verändern sind. Aus der DE 41 37 890 A1 ist eine Betätigungsvorrichtung bekannt, wobei Schnappschaltanordnungen je nach Wahl durch einen Drehknebel oder durch Drucktasten zu betätigen ist. Weder Drehknebel noch Drucktasten nehmen nach dem Loslassen eine dem Schaltzustand der Schnappschaltanordnungen gemäße Position ein, die bei Leistungsschaltgeräten vorgeschrieben ist. Nach DE 21 35 977 A1 kann ein Schaltelement wahlweise mit einem Drehknebel oder einem Druckknopf gegen eine Rückstellfeder verschoben werden, wobei für die Übertragung der Dreh- bzw. Schubbewegung auf das Schaltelement unterschiedliche Stifte und für die Aufrechterhaltung der Schaltstellung unterschiedliche Arretiermittel eingesetzt werden. Diese Betätigungsvorrichtung kann auf eine Betätigungsvorrichtung für ein übliches Schaltschloß mit dreh- oder kippbetätigten Teilen übernommen werden.From DE 42 01 026 A1 a disconnector with variable Manual operation known to change the Type of actuation both the key switch and the actuation shaft are to be changed. DE 41 37 890 A1 is a Actuator known, snap-action arrangements depending on your choice, using a rotary knob or push buttons is pressed. Neither the rotary knob nor the push buttons decrease the release of the switching state of the snap-action switching arrangements according to the position prescribed for power switching devices is. According to DE 21 35 977 A1, a switching element either with a rotary knob or a push button against one Return spring are moved, being used for the transfer of the Rotary or pushing movement on the switching element different Pins and different for maintaining the switch position Locking agents are used.

Der Erfindung liegt die Aufgabe zugrunde, eine Betätigungsvorrichtung der eingangs genannten Art anzugeben, die nach Wahl durch einen Drehknebel oder durch Drucktasten zu betätigen ist.The invention has for its object an actuator of the type mentioned at the beginning, of your choice to be operated by a rotary knob or by push buttons.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Durch die wahlweise Verwendung eines ersten und eines zweiten Gehäuseoberteils mit einem Drehknebel bzw. zwei Drucktasten ist es dem Hersteller bzw. dem Anwender gestattet, die Betätigung des Leistungsschaltgerätes an das gewünschte Erfordernis einfach und unproblematisch anzupassen, ohne daß es dazu Änderungen der physikalischen Eigenschaften der übrigen Bauteile des Leistungsschaltgerätes, insbesondere des Schaltschlosses, beispielsweise hinsichtlich der Entklinkungs-, Einschalt-, Kontaktkräfte etc., bedarf. Dies wird dadurch erreicht, daß die Drucktasten unter Umgehung der Betätigungswelle in der vorgeschlagenen Weise direkt auf die Schaltkulisse einwirken. Auf die Drucktasten wirkende Rückstellfedern, welche eine ständige Wirkverbindung der Drucktasten mit der Schaltkulisse gewährleisten, erlauben eine beliebige Einbaulage des Schaltgerätes.The object is achieved by the features of the claim 1 solved. By optionally using a first and a second upper housing part with a rotary knob or two Pushbuttons are permitted to the manufacturer or the user actuation of the power switching device to the desired one Easily and easily adjust requirement without it in addition changes in the physical properties of the others Components of the power switching device, in particular the switch lock, for example with regard to the unlatching, Switch-on, contact forces etc. required. This will be achieved that the push buttons bypassing the actuation shaft in the proposed manner directly on the shift gate act. Return springs acting on the pushbuttons, which a permanent operative connection of the push buttons with the switching gate ensure, allow any installation position of the Switching device.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. Die Drucktasten sind in vorteilhafter Weise im zweiten vormontierten Gehäuseoberteil unverlierbar gelagert. Zweckmäßig sollte das zweite Gehäuseoberteil gegenüber dem ersten Gehäuseoberteil eine größere Bauhöhe aufweisen, damit die Betätigungswelle von außen unzugänglich ist und um Führungsflächen für die gelagerten Drucktasten zu bilden. In diesem Falle ist es ebenfalls zweckmäßig, zur Einstellung der einheitlichen Auslöser von außen zugängliche Einstellmittel mit einer angepaßten unterschiedlichen Bauhöhe vorzusehen. Ebenfalls zweckmäßig ist die unverlierbare Lagerung der Rückstellfedern im vormontierten zweiten Gehäuseoberteil. Öffnungen in der Drucktaste zur Handeinschaltung ermöglichen das Abschließen des Schaltgerätes im ausgeschalteten Zustand, das heißt, wenn nach Drücken der Drucktaste zur Handabschaltung die aus dem zweiten Gehäuseoberteil herausgetretene Drucktaste zur Handeinschaltung die Öffnungen zum Einhängen von Bügelschlössern freigibt. Dabei verhindert die in ihrer Einschaltstellung verharrende Schaltkulisse das Herausziehen der Drucktaste im eingeschalteten Zustand, um ein fehlerhaftes Abschließen des Schaltgerätes auszuschließen. Dies wird vorteilhafterweise durch den formschlüssigen Eingriff eines Sperrnockens der Schaltkulisse in eine Sperrkulisse der Drucktaste zur Handeinschaltung bewirkt.Further advantageous embodiments of the invention are the See subclaims. The push buttons are more advantageous Way captive in the second pre-assembled upper housing part stored. The second upper part of the housing should be used a greater overall height than the first upper housing part have so that the actuating shaft is inaccessible from the outside is and around guide surfaces for the stored push buttons too form. In this case, it is also appropriate to Setting the uniform triggers accessible from the outside Adjustment means with an adapted different height provided. The captive storage is also useful the return springs in the pre-assembled second housing upper part. Enable openings in the push button for manual activation locking the switchgear when switched off, that is, if after pressing the push button for manual shutdown the push button that emerged from the second upper part of the housing the openings for hanging padlocks for manual activation releases. This prevents it in its on position persistent shifting gate pulling out the push button when switched on, to prevent incorrect closing exclude the switchgear. This will be advantageous through the positive engagement of a locking cam Switching gate in a locking gate of the push button for manual activation causes.
