   Hinter den Ständerwickelungen vereinigen sich die beiden   Zweigströme   und gehen gemeinsam zu dem Kontaktfinger   2   des selbsttätigen Umschalters. Letzterer besitzt acht feststehende Kontaktfinger 21 bis 28 und fünf bewegliche   Kontaktstücke,   zwei längere und drei kürzere. In der gezeichneten Stellung liegen die längeren   Kontaktstücke   auf und es teilt sich der Strom hinter dem Kontaktfinger 24 in dem mit ihm in Berührung befindlichen beweglichen   Kontaktstück   und geht parallel durch beide Anker   (11 (12, nämlich vom   Finger 23 durch den Anker al nach Finger 21, 27   und M   und vom Finger 22 durch Anker a2 nach Fiuger 26 und 28.

 EMI2.1
   Mediation of a dental arch that can be rotated jointly with it turns the switch M back into the start-up position, the spring h being tensioned again and the switch being blocked.



   3 shows an application of the automatic switchover in de (regulation of two motors whose armatures a1 and a are connected in parallel during start-up and are connected in series for the run, while at the same time the one supplied to the motors and removed from the mains transformer t '

   reversed with the direction switch r.



   If the latter and the controller k are switched on, the transformer t, which is earthed at one end, is connected to the power line via the two uppermost fixed contact fingers 1, 2 of the controller and, first of all, its first two groups of windings cut current in the first position, which current is drawn via the fingers 4 and 11 in parallel branches to the direction switch r

 or in another direction depending on the direction switch is turned in one direction or the other, the fixed contact fingers with the left bvw. the moving contact pieces drawn to the right of them come into contact.

   The two branch currents unite behind the stator windings and go together to the contact finger 2 of the automatic changeover switch. The latter has eight fixed contact fingers 21 to 28 and five movable contact pieces, two longer and three shorter ones. In the position shown, the longer contact pieces rest on and the current divides behind the contact finger 24 in the movable contact piece that is in contact with it and runs parallel through both armatures (11 (12, namely from finger 23 through armature a1 to finger 21 , 27 and M and from finger 22 through armature a2 to Fiuger 26 and 28. The current from both armatures then flows
