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.With a spring switch according to the state of the art problems when switching because in the range of Dead center of a spring the driving force is almost zero.

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.

Figure 00000001
A spring switch mechanism (1) designed according to the invention has a spring (3) which is designed such that it reaches its dead center before a central position of the movable part (5), as a result of which it is possible to securely fold over into another stable end position (10, 12) ,
