Claims (5)

1. Betätigungseinrichtung für ein Überlastrelais, mit einer Wippe, an der zwei Kontaktbrücken zur elektrisch leitenden Überbrückung zweier Festkontaktstückpaare federnd gelagert sind und die von einer Steuereinrichtung mit den Kontaktstücken je­ weils in entgegengesetzte Richtung angetrieben wird, und mit einer Umstelleinrichtung auf manuelle und automatische Rückstellung aus einer zweiten in die erste Stellung, dadurch gekennzeichnet, daß die Umstelleinrichtung einen in einem Gehäuse innerhalb des Überstromrelais längs- und gegebenenfalls drehbar geführten Druckknopf aufweist, an dem eine Antriebsstange angebracht ist, die mit der Wippe gekoppelt ist, daß an dem Gehäuse ein Schwenkhebel drehbar angelenkt ist, der einerseits mit der Wippe und andererseits mit der Antriebsstange gekoppelt ist, daß der Schwenkhebel in einer ersten Stellung des Druckknopfes die Wippe in der zweiten Stellung festhält und durch Niederdrücken des Druckknopfes die Wippe freigibt und die Antriebsstange die Wippe in die zweite Stellung verschwenkt, und daß der Druckknopf in der zweiten Stellung drehbar ist und beim Verdrehen den Schwenkhebel von der Wippe freischwenkt, so daß die Wippe in dieser Stellung in beide Richtungen verschwenkbar ist.1.Actuating device for an overload relay, with a rocker on which two contact bridges for the electrically conductive bridging of two pairs of fixed contact pieces are spring-loaded and which are driven in each case in opposite directions by a control device with the contact pieces, and with a changeover device for manual and automatic resetting a second to the first position, characterized in that the changeover device has a push button which is longitudinally and optionally rotatably guided in a housing within the overcurrent relay and to which a drive rod is attached, which is coupled to the rocker, and that a pivot lever is rotatable on the housing is articulated, which is coupled on the one hand to the rocker and on the other hand to the drive rod, that the pivot lever holds the rocker in the second position in a first position of the push button and releases the rocker by depressing the push button and the Ant Riebsstange the rocker pivoted into the second position, and that the push button is rotatable in the second position and pivoted when pivoting the pivot lever of the rocker, so that the rocker is pivotable in both directions in this position. 2. Betätigungseinrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Antriebsstange durch einen Arm einer Schraubenfeder gebildet ist, dessen freies Ende abgewinkelt und gegen die Wippe drückbar ist.2. Actuating device according to claim 1, characterized in that the drive rod is formed by an arm of a coil spring, the free Angled end and can be pressed against the rocker. 3. Betätigungseinrichtung nach Anspruch 2, dadurch gekennzeichnet, daß am Schwenkhebel ein Querzapfen vorgesehen ist, an dem die Schraubenfeder gela­ gert ist.3. Actuating device according to claim 2, characterized in that a cross pin is provided on the swivel lever, on which the coil spring gela device. 4. Betätigungseinrichtung nach einem der vorigen Ansprüche, dadurch ge­ kennzeichnet, daß am Gehäuse ein Nockensteg angeformt ist, der das abgewinkelte Ende der Antriebsstange beim Niederdrücken des Drehknopfes gegen die Wippe führt und beim Freigeben von der Wippe entfernt, dadurch, daß das abgewinkelte Ende auf einer Seite gegen die Wippe geführt wird und auf seiner anderen Seite von der Wippe weggesteuert wird. 4. Actuating device according to one of the preceding claims, characterized ge indicates that a cam web is formed on the housing, which is the angled End of the drive rod when pressing the rotary button against the rocker and removed from the rocker when released, in that the angled end on one side is guided against the seesaw and on the other side of the seesaw is steered away.   5. Betätigungseinrichtung nach einem der vorigen Ansprüche, dadurch ge­ kennzeichet, daß am Drehknopf ein Arm angeformt ist, der beim Verdrehen den Schwenkhebel dauernd von der Wippe freihält.5. Actuating device according to one of the preceding claims, characterized ge indicates that an arm is formed on the knob, which when twisted Keep the swivel lever free from the rocker.
