  Wähler zur Herstellung von Verbindungen In Fernsprechanlagen. 



   Im Stammpatente Nr. 68536 ist ein Wähler beschrieben, bei welchem ein mechanisch betriebenes Einstellorgan auf dem Kontakt einer gewünschten Leitung mitl) ilfe einer besondern Sperrvorrichtung festgestellt wird. Diese Sperrung steht unter dem Einfluss eines Prüfelektromagneten, dem lediglich die Aufgabe zufällt, das Sperrglied in der Sperrlage, in welche es auf mechanischem Wege gebracht wird, festzuhalten. 



   Die durch diese Anordnung   ermöglichte grössere Einstellgeschwindigkeit   des Wählers

 artige Schwingungen versetzte Sperrglied nicht nur an einem Umkehrpunkt, sondern an beiden   Umkehrpunkten   seiner Bewegung von einem Prüfelektromagneten magnetisch beeinflusst werden kann.   Es ermöglicht   dies, unter sonst   gleichbleibenden Umstanden innerhalb eines gegebenen   
 EMI1.2 
 



     Zweckmässig   werden hiebei die an beiden Umkehrpunkten des Sperrgliedes vorgesehenen Prüfmagnete vormagnetisiert. z. B. durch Anwendung permanenter Magnete oder dadurch. dass der   Prüfarm   dem Sperrad mit Bezug auf die Kontakte um ein geringes voreilt, so dass er schon in Berührung mit einem fieien Kontakt kommt, ehe noch das Sperrglied in das Sperrad   einschnappt. Der vormagnetisierte Prüfelektromagnet kann   das Sperrglied dann mit voler   K mft festhalten, sohald e8   in seine Sperrstellung gelangt. 



   Beim   Auftrefen   auf eine freie Leitung werden zweckmässig die beiden Prüfelektromagnete geleichzeitig magnetisiert, was eine sehr einfache Schaltung zur Folge hat. 



   Die Zähne des mit dem Sperrglied zusammenarbeitenden Sperrades werden   zweckmässig

  Selector for making connections in telephone systems.



   In the parent patent no. 68536 a selector is described in which a mechanically operated setting element is determined on the contact of a desired line with the aid of a special locking device. This blocking is under the influence of a test electromagnet, which only has the task of holding the blocking element in the blocking position into which it is mechanically brought.



   The greater setting speed of the selector made possible by this arrangement
 EMI1.1
 Like vibrations offset locking member can be magnetically influenced by a test electromagnet not only at a reversal point, but at both reversal points of its movement. It enables this, all other things being equal, within a given
 EMI1.2
 



     The test magnets provided at both reversal points of the blocking element are expediently premagnetized. z. B. by using permanent magnets or thereby. that the test arm leads the ratchet wheel by a small amount with respect to the contacts, so that it already comes into contact with a free contact before the locking member snaps into the ratchet wheel. The pre-magnetized test electromagnet can then hold the locking member with full K mft so that e8 reaches its locking position.



   When encountering a free line, the two test electromagnets are expediently magnetized at the same time, which results in a very simple circuit.



   The teeth of the ratchet wheel cooperating with the locking member become useful
