  SchaltwerkfürFernsprechanlagenmitwählerbetrieb. 
 EMI1.1 
 die mit Selbstinduktion behaftet sind, in Erscheinung tritt. 



   Die neuen Schasltwerke können derart geschaltet werden. dass sie als Anrufsucher, Gruppenwähler oder Leitungswähler verwendet werden. 
 EMI1.2 
 Kontaktfeldes vorgesehen. 



   Zum Antreiben der Kontaktarme kann zweckmässig eine aufgezogene Feder dienen, die in der   Ruhelage des Schaltwerkes durch die Klinke eines Elektromagneten   oder eines Relais,   weiches     ans einem   Halbleiter, wie z. B. einer   Achatschicht,   und einer damit in   Berührung   stehenden, federnden Metallbelegung besteht, die bei Stromdurchgang durch den Halbleiter und die Metallbelegung sich gegen die Achatschicht bewegt, unter Spannung gehalten wird. Ein solches Relais wird im nachfolgenden einfach   als Halbleiterrelais bezeichnet.   Die Halbleiter bzw. der Halbleiter, die zum An4trieben bzw. Arretieren der beweglichen Teile des Schaltwerkes dienen. können   scheibenförmig oder zylindrisch gestaltet sein.   



   Die Erfindung ist beispielsweise in der Zeichnung dargestellt, in welcher Fig. 1 ein schematisches 
 EMI1.3 
 des Zahnrades : 1 eingreift. 



   16 ist eine viereckige Stange, die durch das Loch eines Rahmenteiles 17 hindurchgeht und an deren unterem Ende eine Scheibe 14 aus Metall und eine Scheibe   15, aus einem Halbleiter besteh@nd,   befestigt ist.

  Switchgear for telephone systems with dialer operation.
 EMI1.1
 which are afflicted with self-induction appears.



   The new Schasltwerke can be switched in this way. that they can be used as a call finder, group dialer or line dialer.
 EMI1.2
 Contact field provided.



   To drive the contact arms, a wound spring can be useful, which in the rest position of the switching mechanism by the pawl of an electromagnet or a relay, soft on a semiconductor such. B. an agate layer, and a resilient metal coating in contact therewith, which when current passes through the semiconductor and the metal coating moves against the agate layer, is kept under tension. Such a relay is referred to below simply as a semiconductor relay. The semiconductors or semiconductors that are used to drive or lock the moving parts of the switching mechanism. can be disc-shaped or cylindrical.



   The invention is illustrated for example in the drawing, in which Fig. 1 is a schematic
 EMI1.3
 of the gear: 1 engages.



   16 is a square rod which passes through the hole of a frame part 17 and at the lower end of which a disk 14 made of metal and a disk 15 made of a semiconductor is attached.
