   Auch die Ausschaltung ist derart, dass man nicht im Unklaren sein kann, ob der Batteriestromkreis offen oder geschlossen ist.   Bai   den jetzt für die Zündung im Gebrauch befindlichen Druckknopfkontakten ist es nicht ausgeschlossen, dass ein bzw. beide Druck. kontakte beim Niederdrücken sich festklemmen und sitzen bleiben. Werden nun die Anschlussklemmen an den   Druckknöpfen   von den Zündleitungsdrähten berührt, so findet die Zündung vorzeitig statt. Diesem Übelstahd ist bei dieser Erfindung vorgebeugt, indem es auf den ersten Blick erkennbar ist, wenn einer der'Hebel in der Kontaktstollung stehen geblieben ist.

   Ferner ist hei den durch Druckknöpfo bedienten Zündvorrichtungen die Möglichkeit vorhanden, dass durch Oxydation der   Borührunganächon   dem ohnehin schon schwachen Strom ein nicht unerheblicher Widerstand entgegengesetzt wird, wodurch leicht Versager eintreten können. Bei dieser Erfindung ist dies   unmöglich,   da der Kontakt durch Reibung hergestellt wird, wodurch die Berührungsflächen immer blank erhalten werden.

   The switch-off is also such that one cannot be in the dark as to whether the battery circuit is open or closed. With the push-button contacts now in use for the ignition, it is not excluded that one or both pressures. contacts get stuck when pressed down and stay seated If the connection terminals on the push buttons are touched by the ignition lead wires, the ignition takes place prematurely. This evil is prevented in this invention in that it can be seen at first glance when one of the levers has stopped in the contact tunnel.

   Furthermore, with the ignition devices operated by pushbuttons, there is the possibility that a not inconsiderable resistance is opposed to the already weak current by oxidation of the boron lead, which can easily lead to failure. In this invention this is impossible because the contact is made by friction, whereby the contact surfaces are always kept bright.
