Description

Bei axial gesteuerten N ockenschaltern liegen gewöhnlich auf jeder Seite der Achse quer zur Achsrichtung mehrere Kontakthebel. Sofern die Anzahl der Kontakthebel gerade ist, können die Hebel bequem auf beiden Seiten der Achse verteilt werden. Es gibt aber auch Nockenschalter, welche eine ungerade Anzahl von Kontakthebeln erfordern, so daß ZB. bei drei Hebeln auf der einen Seite der Achse sich zwei und auf der anderen Seite ein Hebel befinden. Dieses würde eine ungünstige Raumverteilung innerhalb des Schalters bewirken, so daß Leerräume entständen, die den Schalter entweder vergrößern oder einseitig gestalten würden. Um diesen Mangel an solchen Schaltern zu beseitigen, wird bei solchen Schaltern erfindungsgemäß ein Kontakthebel mit einer Erweiterung versehen, durch welche die Achse oder ein Fortsatz der Steuerscheibe hindurchtreten kann. Haben die ertvähnten \Tockenschalter Kontakthebel, die an ihren Enden, z. B. durch den Kontaktklotz,-mit eitler Blattfeder fest verbunden sind, so besitzt der Hebel -die genannte Erweiterung an der mit dein Steuernocken zusammenwirkenden Abkröpfung, so daß sich die Achse oder ein Fortsatz der Steuerscheibe in dieser Erweiterung frei bewegen kann.Axially controlled cam switches usually have each Side of the axis transverse to the axis direction several contact levers. Provided the number of If the contact lever is straight, the levers can be conveniently distributed on both sides of the axis will. But there are also cam switches which have an uneven number of contact levers require, so that ZB. if there are three levers on one side of the axis, two and there is a lever on the other side. This would result in an unfavorable distribution of space inside the switch, so that there would be empty spaces that the switch either enlarge it or make it one-sided. To this lack of such To eliminate switches, a contact lever is used in such switches according to the invention provided with an extension through which the axis or an extension of the control disc can pass through. Do the aforementioned \ toe switches have contact levers attached to their Ends, e.g. B. are firmly connected by the contact block, -with vain leaf spring, The lever has the mentioned extension on the one that interacts with your control cam Bend so that the axis or an extension of the control disk is in this Extension can move freely.

Abb. i zeigt eine Draufsicht auf den Schalter und Abb. 2 einen Längsschnitt durch denselben. Der mittlere der drei Kontakthebel i, 2 und 3 besitzt die Erweiterung-i, welche mit der Durchtrittsöffnung 5 versehen ist und durch welche -der Fortsatz 6 (Abt. 2) der Steuerscheibe 7 hindurchtritt. Die Erweiterung 5 ist so groß,- daß sich der Kontakthebel 2 frei bewegen kann. Der Kontakthebel 2, der durch den Kontaktklotz 8 mit der Blattfeder 9 verbunden ist, besitzt an seiner durchbrochenen Stelle eine Abkröpfung -iio, welche mit dem Nocken i i der Steuerscheibe; zusammenwirkt. Auf diese Weise kann sich der Hebel 2 in der Blattfeder 9 frei auf und ab bewegen, ohne daß er an dem Fortsatz 6 dadurch behindert wird.Fig. I shows a plan view of the switch and Fig. 2 shows a longitudinal section through the same. The middle of the three contact levers i, 2 and 3 has the extension -i, which is provided with the passage opening 5 and through which -the extension 6 (section 2) of the control disk 7 passes. The extension 5 is so big - that the contact lever 2 can move freely. The contact lever 2, which is through the contact block 8 is connected to the leaf spring 9, has a at its perforated point Bend -iio, which with the cam i i of the control disk; cooperates. on in this way, the lever 2 can move freely up and down in the leaf spring 9 without that it is hindered by the extension 6.
