Abstract

Das Antriebssystem hat zwei Kontaktfedern (2, 3), die durch einen Schieber (7) zwischen einer Schließ- und einer Öffnungsstellung verschiebbar sind. Damit nur kurze Verstellwege zum Schließen und zum Öffnen des Kontaktes erforderlich sind, sind die beiden Kontaktfedern (2, 3) gegensinnig zueinander bewegbar. Dadurch sind die Verstellwege zum Schließen und Öffnen des Kontaktes sehr gering. Die Kontaktkraft wird durch die gegensinnige Bewegung und eine Federdurchbiegung über den Punkt der Kontakgabe hinaus aufgebracht. Aufgrund dieser gegensinnigen Bewegung der Kontaktfedern (2, 3) werden ein sehr kurzer Verschiebeweg und damit sehr kurze Stell- bzw. Schaltzeiten erreicht.

Figure 00000001
The drive system has two contact springs (2, 3) which can be moved between a closed and an open position by a slide (7). So that only short adjustment paths for closing and opening the contact are required, the two contact springs (2, 3) can be moved in opposite directions to one another. As a result, the adjustment paths for closing and opening the contact are very small. The contact force is applied by the opposite movement and a spring deflection beyond the point of contact. Due to this opposite movement of the contact springs (2, 3), a very short displacement path and thus very short actuation or switching times are achieved.
