Da das Relais Y seinen Anker verzögert abfallen lässt, so genügt die Zeit der Öffnung der Kontakte. y. und Y. um die Relais F und J abzuerregen, wodurch der Drohmagnct Diw und das Relais X erregt werden und der Impulswahler in die Ruhelage zurückkehrt. Nach dem ersten Schritt des Impulswählers bleibt das Relais F aberregt, während durch das Relais X über Erde, Batterie, kit Hr. ! dz Erde ein verzögerungsrelais Hr erregt wird, welches sich über seinen Arbpeltskontakt hr. in einen Haltestrom-

Diese Anordnung hat gegenüber der erstgenannten noch den Vorteil, dass für die Auslösung der eingeschalteten Wähler des Sprechweges und Belegung eines anderen Wählersatzes bedeutend mehr Zeit vorhanden ist, als wenn die Auslösung des Sprechweges erst nach dem Auslösen des Impulswähh'rs erfolgen würde.

Since the relay Y lets its armature drop out with a delay, the time for the contacts to open is sufficient. y. and Y. to de-energize the relays F and J, whereby the threat magnct Diw and the relay X are energized and the pulse selector returns to the rest position. After the first step of the pulse selector, relay F remains de-energized, while relay X is connected to earth, battery, kit Hr. ! dz earth a delay relay Hr is excited, which is converted into a holding current via its work contact hr.

Earth switches on in a holding circuit, the pulse selector switches on again, which adjusts the reset selector, which is now occupied by a preselector IIVW '.
This arrangement has the advantage over the first mentioned that there is significantly more time for the activated dialer of the speech path to be triggered and for another dial set to be activated than if the speech path were only released after the impulse dialer had been triggered.
In the embodiment shown, the creation of a spech path is repeated for as long as the test current cycle does not occur. than the calling tell

Stepping mechanism the device is made that the number of repetitions is determined. After the last attempt, the relay chain or the step-by-step switch can prevent the triggering again and a monitoring control can be switched on for the office staff so that they can determine the cause of the faulty connections.
