Description

Bei der Handhabung elektrischer Hebelschalter kommt es leicht vor, daß infolge geringerer Sorgfalt oder aus anderen Grund en der Schalthebel durch den ihn Bedienenden an dem Handgriff gezogen und dadurch mit seinem Kontaktteil von den ruhenden Kontaktstücken abgehoben wird. Dadurch entstehen Stromunterbrechungen, elektrische Entladungen zwischen den voneinander abgehobenen Kontaktteilen und in weiterer Folge Schädigungen dieser Kontaktteile oder gar auch noch anderer Teile des Stromkreises.When handling electric lever switches, it easily happens that as a result of lesser Care or for other reasons s the shift lever by the operator at the Handle pulled and thereby with its contact part of the stationary contact pieces is lifted. This creates power interruptions, electrical discharges between the contact parts lifted from one another and, as a result, damage to them Contact parts or even other parts of the circuit.

Dieser Nachteil ist durch die Erfindung beseitigt. Bei dem neuen Hebelschalter, der .in einer Ausführungsform in der Abbildung im Längsschnitt dargestellt ist, wird die Kontaktfederbrücke σ durch einen nur an dem Handhebel b befestigten Bolzen c lose durchsetzt, der auch durch die Grundplatte d lose hindurchgeführt ist und mittels der Feder e gegen die Grundplatte hingezogen und auf diese Weise an die Kontaktfederbrücke α angedrückt wird. An dem Handhebel b ist noch der Mitnehmerstift/ befestigt, welcher ebenfalls lose durch die Kontaktfederbrücke α hindurchgreift und die Kontaktf ederbrücke α bei der Bewegung des Handhebels b auch dann mitnimmt, wenn der Handhebel b an dem Handgriff g von der Grundplatte weggezogen wird. Durch diese lose Anordnung des Mitnehmers gegenüber der Kontaktfederbrücke α bleibt das Anliegen der Kontaktfederbrücke α an den ruhenden Kontaktteilen h und i von dem an dem Handgriff ausgeübten Zug unbeeinflußt.This disadvantage is eliminated by the invention. In the new lever switch, which is shown in longitudinal section in one embodiment in the figure, the contact spring bridge σ is loosely penetrated by a bolt c attached only to the hand lever b , which is also loosely passed through the base plate d and counteracted by means of the spring e the base plate is pulled and in this way pressed against the contact spring bridge α. The driver pin / is still attached to the hand lever b , which also loosely passes through the contact spring bridge α and takes the contact spring bridge α with it when the hand lever b is moved, even if the hand lever b on the handle g is pulled away from the base plate. Due to this loose arrangement of the driver relative to the contact spring bridge α , the contact between the contact spring bridge α and the stationary contact parts h and i remains unaffected by the pull exerted on the handle.

Im Gegenteil wirkt dadurch das hintere Ende k des Handhebels b, wenn dieser an dem Handgriff g von der Grundplatte d weggezogen wird, auf die Kontaktfederbrücke a so, daß der Druck der Kontaktf ederbrücke a auf das ruhende Kontaktstück h vergrößert, der Druck der Kontaktfederbrücke α auf das Kontaktstück i aber, da das hintere Ende des Handhebels nahe der Achse der von dem Handhebel infolge des Zuges ausgeübten Drehung liegt, merklich unverändert bleibt.On the contrary , when the handle g is pulled away from the base plate d, the rear end k of the hand lever b acts on the contact spring bridge a in such a way that the pressure of the contact spring bridge a on the stationary contact piece h increases, the pressure of the contact spring bridge α on the contact piece i, however, since the rear end of the hand lever is close to the axis of the rotation exerted by the hand lever as a result of the pull, remains noticeably unchanged.
