Description
Gegenstand der Erfindung ist ein Momentschalter derjenigen Art, bei welcher der nur in der Einschaltrichtung vom Handhebel des Schalters mitgenommene Stromschlußhebel in der Einschaltstellung von einer ,Sperrklinke festgehalten wird, die bei genügend weiter Rückwärtsbewegung des Handhebels wieder ausgerückt wird, so daß dann der Stromschlußhebel rasch in die Unterbrechungsstellung zurückkehrt.The invention relates to a momentary switch of the type in which the only Current circuit lever carried along by the hand lever of the switch in the switch-on direction is held in the on position by a pawl, which continues when sufficient Backward movement of the hand lever is disengaged again, so that then the current circuit lever quickly returns to the interruption position.
Von den bisher bekannt gewordenen Schal- ■ tern dieser Art unterscheidet sich der neue dadurch, daß er besonders einfach ist und daher billig und in kleinen Abmessungenhergestellt werden kann, also für kleine Apparate, wie Handbohrmaschinen o. dgl., geeignet ist.The new one differs from the previously known ■ switches of this type in that it is particularly simple and therefore cheap and small in size Can be, so for small devices such as hand drills o. The like., Is suitable.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der beiliegenden Zeichao nung veranschaulicht.An embodiment of the subject matter of the invention is shown in the accompanying drawing a illustrated.
Abb. ι zeigt den geschlossenen Schalter in Seitenansicht.Fig. Ι shows the closed switch in side view.
Abb. 2 ist ein Grundriß zu Abb. 1. Abb. 3 zeigt den Schalter einen Augenblick vor Stromunterbrechung.Fig. 2 is a plan view of Fig. 1. Fig. 3 shows the switch for a moment before power interruption.
Abb. 4 zeigt den Schalter in Ausschaltstellung. Fig. 4 shows the switch in the off position.
Das Schaltmesser α ist zwischen zwei um die Achse d gewundenen Federn b und c um jene Achse drehbar gelagert und wird durch eine am Schaltmesser angelenkte Klinke e, die mit ihrer Nase in eine Ausnehmung der Grundplatte g eingreift, in der in Abb. 1 gezeichneten Lage zwischen den Kontaktfedern festgehalten.The switch blade α is mounted rotatably around that axis between two springs b and c wound around the axis d and is in the position shown in Fig. 1 by a pawl e hinged to the switch blade, which engages with its nose in a recess in the base plate g held between the contact springs.
Die eine der beiden Federn (b) wirkt auf die Klinke e derart ein, daß sie diese in der Stellung gemäß Abb. 1 zu erhalten sucht.One of the two springs (b) acts on the pawl e in such a way that it tries to maintain it in the position shown in FIG.
Wird der ebenfalls um die Achse d schwingbare Handhebel h unter der Wirkung der Feder c nach oben bewegt, weil von Hand losgelassen, so bleibt zunächst das Schalt-, messer α in den Kontaktfedern liegen. Erst wenn ein am Handhebel h angebrachter Anschlagstift g1 sich gegen das rückwärtige Ende der Klinke e gelegt hat, tritt ein Ausschwingen der Klinke e bei weiterer Aufwärtsbewegung des Hebels h und des Stiftes g entgegen der Wirkung der Feder b ein, bis, nach Überschreitung der in Abb. 3 gezeichneten Stellung, die Klinkennase vom Rande der Ausnehmung in der' Grundplatte g abgleitet und nun das Schaltmesser α, der Wirkung der Feder b folgend, in die Stellung gemäß Abb. 4 emporspringt.If the hand lever h , which can also swing about the axis d, is moved upwards under the action of the spring c because it has been released by hand, the switching knife α initially remains in the contact springs. Only when a stop pin g 1 attached to the hand lever h has come to rest against the rear end of the pawl e does the pawl e swing out upon further upward movement of the lever h and the pin g against the action of the spring b , until, after exceeding the The position shown in Fig. 3, the latch nose slides off the edge of the recess in the 'base plate g and now the switch blade α, following the action of the spring b , jumps up into the position shown in Fig. 4.
■ ,Der Stift g dient außer zum Ausschwingen der Klinke e auch noch als Anschlag und als Mitnehmer für das Schaltmesser.■, In addition to swinging out the pawl e , the pin g also serves as a stop and as a driver for the switch blade.
Wird der Hebel h aus der Stellung gemäß Abb. 4 in die Stellung gemäß Abb. 1 herabgedrückt, so drückt der Stift g das Schaltmesser in die Stromschlußstellung, Wird dagegen der Hebel h losgelassen, so tritt in der vorhin erläuterten Weise nach Zurücklegung eines bestimmten Weges des Hebels h selbsttätig augenblickliche Ausschaltung ein.If the lever h is pressed down from the position shown in Fig. 4 into the position shown in Fig. 1, the pin g pushes the switch blade into the current-closed position, if, on the other hand, the lever h is released, the previously explained way of covering a certain distance occurs the lever h automatically switches off instantaneously.
Die Kontaktanordnung am Schalter ist natürlich in beliebiger Weise ausführbar. Ebenso ist der Schalter für ganz verschiedenartige Zwecke anwendbar.The contact arrangement on the switch can of course be implemented in any way. The switch can also be used for a wide variety of purposes.
