    - eine bewegliche Einheit (60), die geeignet ist, eine Steuerstange (68), auf der ein elektrisches Kontaktelement (58) vorgesehen ist, entlang einer Längsachse (X) zu verschieben,
    - zwei elektrische Hilfskontaktklemmen (51, 52), die geeignet sind, einen ersten elektrischen Kontakt (45) zu bilden, wenn das elektrische Kontaktelement (58) im Wesentlichen an diesen beiden Hilfsklemmen (51, 52) aufliegt, wobei es sie elektrisch verbindet, und
    - zwei elektrische Hauptkontaktklemmen (53, 54), die geeignet sind, einen zweiten elektrischen Kontakt (46) zu bilden, wenn das elektrische Kontaktelement (58) im Wesentlichen an diesen beiden Hauptklemmen (53, 54) aufliegt, wobei es sie elektrisch verbindet,
    dadurch gekennzeichnet, dass der Kontaktschalter derart vorgesehen ist, dass die beiden Hilfsklemmen (51, 52) durch das elektrische Kontaktelement (58) entlang der Längsachse (X) zwischen einer Position, in der das elektrische Kontaktelement (58) im Wesentlichen an den Hilfsklemmen (51, 52) aufliegt, und einer Position, in der das elektrische Kontaktelement (58) ferner im Wesentlichen an den Hauptklemmen (53, 54) aufliegt, verschiebbar sind.
