Description
Die Erfindung betrifft einen Kipphebelschalter, dessen Kontaktglied an dem Antriebshebel in axialer Richtung verschiebbar gelagert ist und von ihm aus der einen in die andere Schaltstellung bewegt wird, wobei es zum Zwecke der Verrastung in den Endstellungen mittels einer an ihm angebrachten Rolle federnd gegen eine Rasten aufweisende Gleitbahn gedrückt wird. ErfindungsgemäßThe invention relates to a toggle switch, the contact member of which is on the drive lever is mounted displaceably in the axial direction and is moved by it from one switch position to the other, wherein it for the purpose of locking in the end positions by means of an attached to it Roller is resiliently pressed against a slideway having notches. According to the invention
to wird bei einem derartigen Schalter eine von der Bewegung des Antriebshebels unabhängige Momentschaltung dadurch erreicht, daß das die Ein- und Ausschaltung bzw. Umschaltung bewirkende Schaltglied im Drehpunkt des Antriebshebels verschiebbar gelagert ist, so daß es sich gleichzeitig um die Welle des Antriebshebels drehen kann. Zur Momentschaltung dient eine um die Antriebshebelachse herum angeordnete und vom Antriebshebel gespannte Torsionsfeder, die das Kontaktglied mittels der Führungsrolle gleichzeitig gegen die Gleitbahn drückt. Ist die Torsionskraft der Schaltfeder durch die Bewegung des Antriebshebels so groß geworden, daß die Führungsrolle aus der Bahnrast herausgleitet, so wird das Kontaktglied momentan aus der eingenommenen Schaltstellung herausgezogen und auf die andere Schaltstellung zu bewegt. Es springt dann, sobald es nur eine ganz geringe Strecke seine Mittelstellung überschritten hat, selbsttätig ohne Einfluß des Betätigungsorgans in die andere Endstellung. Die Führungsbahnrasten sind dementsprechend in den beiden Endstellungen angeordnet, so daß sie die an dem Schaltglied angebrachte Rolle festhalten. Der Schalter kann also niemals in der für den Schaltvorgang gefährlichen Zwischenstellung stehenbleiben und Stehfeuer verursachen.With such a switch, to becomes independent of the movement of the drive lever Momentary switching achieved in that the switching on and off or switching causing switching element is slidably mounted in the pivot point of the drive lever, so that it can rotate around the shaft of the drive lever at the same time. To the momentary switching a torsion spring, which is arranged around the drive lever axis and is tensioned by the drive lever, serves as the contact element presses against the slide at the same time by means of the guide roller. Is the torsional force of the switching spring due to the movement of the drive lever has become so large that the guide roller slides out of the track notch, so the contact member is momentarily pulled out of the assumed switching position and to the other switching position too moved. It then jumps as soon as it is only a very short distance from its middle position has exceeded, automatically without influence of the actuator in the other end position. The guideway notches are accordingly arranged in the two end positions, so that they are the on the switching element Hold the attached roller. The switch can therefore never be used for the switching process stop dangerous intermediate position and cause standing fire.
Zwischen dem Betätigungsorgan 1 (Abb. 1 und 2), welches mit einem Mitnehmer 2 fest verbunden ist, und dem Schaltglied 3 ist eine die Momentschaltung bewirkende Vorspannfeder 4 angeordnet. Die beiden Schenkel 5 und 6 dieser Feder stützen sich in der Ruhestellung an dem Schaltglied 3 ab, wobei sie gleichzeitig in Längsrichtung des Schaltgliedes einen Druck auf dasselbe ausüben. Das Schaltglied 3, in welchem eine Rolle 7 gelagert ist, wird durch die Feder 4 in seinen Endstellungen vermittels dieser Rolle 7 auf eine Gleitbahn 8 gedrückt. Das Schaltglied 3 ist in seinem Drehpunkt in Längsrichtung verschiebbar ausgebildet.Between the actuator 1 (Fig. 1 and 2), which is firmly connected to a driver 2, and the switching element 3 is a arranged the biasing spring 4 causing the momentary shift. The two legs 5 and 6 of this spring are supported in the rest position on the switching element 3, whereby they simultaneously exert a pressure on the same in the longitudinal direction of the switching element. That Switching element 3, in which a roller 7 is mounted, is by the spring 4 in his End positions pressed onto a slide 8 by means of this roller 7. The switching element 3 is designed to be displaceable in the longitudinal direction at its pivot point.
Zu diesem Zwecke sind am oberen Teile desselben Schlitze 9, 10 vorhanden, vermittels denen es an der Achse 11 auf und ab gleiten kann. Die Gleitbahn 8, welche im wesentlichen geradlinig ist, besitzt an ihren Enden kleine Vertiefungen 12 und 13, welche die Rolle 7 des Schaltgliedes 3 in den Endstellungen sicherer festhalten.For this purpose, slots 9, 10 are provided on the upper part of the same, by means of which it can slide up and down on the axis 11. The slide 8, which essentially is straight, has small recesses 12 and 13 at their ends, which the Hold the roller 7 of the switching element 3 securely in the end positions.
Wird das Betätigungsorgan 1 um einen gewissen Winkel gedreht, so spannt der Mitnehmer 2 durch Abheben eines Schenkels der Vorspannfeder 4 die letztere an. Der zweiteIf the actuator 1 is rotated through a certain angle, the driver tensions 2 by lifting one leg of the biasing spring 4, the latter on. The second
