Description

Dial up connection.

Display devices such as incandescent lamps and their cables and sockets are therefore not required.

The invention relates to a preselector with 45 taken. Since the keystroke buttons are mutual a register that z. B. have after a decadic Sy triggering, can be a manufactured Anwahlstem is arranged, with which to preselect the first! connection in a simple manner by pressing the len nine switches with the digits as well as a zero-correct key can be corrected. A delete key switches of a series can be combined with decade - is therefore not required, and it is also possible to switch, as well as only one for registering the eggs, the individual combinations in arbitrary clean places to select the serving zero switch in the next sequence.

Row, whereby conversely the zero position switch serves the if - as provided in accordance with a further development of the invented single position row for registering the decade zero - the push button switch serves. next higher decade with additional switching contacts are equipped with this known preselecting device (German clocks, the electromagnetic see Auslegeschrift 1 040111) are the pushbutton interlocking associated electromagnetic syder tens row via control wire with the exciter star briefly interrupted by a timing relay windings of blockre ' .ais will be used for further decades, so άΐ3 when using the preselection device. The excitation windings of this block relay for controlling a specialist finder at Pater are connected. The push-button switches for the one-time cabinets in a simple way, the stored places are automatically deleted via control conductors on the block relay combination and the block relay clocks for the next deca, the preselection device is then connected again for a new one. Each block relay contains when an input is ready.

Block relay contacts to the excitation windings of the 65 so that the pressed switch will disengage

Hundreds of selection relays are connected, which in turn are expediently connected to the contactor via opening contacts

again with the other potential of the DC voltages of the control of the drive motor for the father

power source are connected, which enables the noster cabinet when it is switched off

Claims (3)

The patent claims: purposeful simplification of the operation of switchgear by reducing the area of the 1. Preselection device with a register, the monitoring panels are - as described - only z. B. is arranged according to a decadic system, 5 mii large equipment and circuitry / vuibei nine Schalwan-i can be achieved for preselecting the units digits. It must be related to that ter with the digits as well as a zero switch a push button switch of the higher decades ten relays with Row can be combined with decade switches, self-holding circuit is assigned /.usatzucn is as well as with a delete switch for registration of the single digits len serving zero switch of the next io of the relay holding circuits is necessary. In addition Row, the reverse being the zero switch still comes that a registration of the manufactured the single-digit row for registering the Deka line connection only by additionally m the Dennull serves, characterized, pushbutton switches protruding bulbs displayed that the switches (1 to 15) can be locked in rows. gel- and releasable push-button switches are also designed to reduce the effort required for the preselection switch (1 to 10), because a fully occupied row of decades with its parallel selection is direction-dependent. The buttons must be switched Inputs (19) often switched always in a certain order. Who are with outputs (18) of the selector switch (12 den.
