Abstract

Bei einem Sprungschaltwerk nach dem Stand der Technik kommt es beim Umschalten zu Problemen, weil im Bereich des Totpunkts einer Feder die antreibende Kraft nahezu null ist.
Ein erfindungsgemäss ausgebildetes Sprungschaltwerk (1) hat eine Feder (3), die so ausgebildet ist, dass sie ihren Totpunkt vor einer Mittellage des beweglichen Teils (5) erreicht, wodurch ein sicheres Umklappen in eine andere stabile Endlage (10,12) möglich ist.
