The innovation concerns a provision for information input bfew * generation of a code / for a number A specific code is assigned to each key And combine every key with a vain Köntäktelement i

There are means for information input or ₄ generating a code known. You will e.g. B * used for data input in computer systems> for information input in computer-controlled machines / in teleprinting devices and the like * The known devices consist of a keyboard and a downstream evaluation electronics. According to their function, the keys on the keyboard are simple switches which, when actuated, send an uncoded signal to the evaluation electronics via appropriate wiring. The evaluation electronics then generate a code according to their programming, which is assigned to the respectively actuated key, and forwards it for further data processing.

These devices have the disadvantage that they * due to the evaluation electronics required are expensive and not very flexible. An adaptation to different tasks, e.g. B. in use of computer-controlled machine tools

Namely, urgent ModifigierUrig deif ÄUäwerteelekfeiföniki This can only be carried out by highly specialized staff and is therefore time-consuming ,

It is the task of innovation to deal with these disadvantages of the estate avoid the technology and a device for information entry or * to create a code / which can thus be produced particularly economically, that it does not require any downstream evaluation electronics * Furthermore, the device should be particularly flexible and can be easily adapted to different uses.

In a device of the type mentioned at the outset, this object is achieved according to the invention in that each contact element by actuating the associated buttons with a number of secondary contact fields and a primary contact field can be brought into interaction to emit a signal and rails are present are to the primary contact fields the signal conductive with an input slider and all of the same type to be able to connect secondary contact fields with an output rail.

The contact element is advantageous when the button is pressed

Each of the buttons 2 has a pin 13 connected to it the cover plate 12 of the housing 14 and the insulating support 7 penetrates. On the pin 13 are above and springs 10 and 11 arranged below the cover plate 12. Between the cover plate 12 and the spring 11 is ei ^ Stop 15 firmly connected to pin 13. The pin 13 carries the contact element 1 in its lower area. The contact element 1 is designed as a snap disk provided with contact arms 6.

The contact fields 3 ¹ and 3 ″ are combined into groups which are each assigned to a key 2. Eight external contacts 3 ″ are arranged peripherally around a center contact 3 ′. Furthermore, conductive rails 4 and 9 are provided on the upper side and the lower side of the insulating carrier 7. The contact fields 3 'and 3 "are connected via the rails 9 to the rails 4 through bores 8 in the following way: The rail 4' is the input rail and with it all the central Köntäkt fields 3 'are connected. The peripheral contact fields 3" are partially depending on the desired coding with the remaining rails 4, which are output rails, connected. All of the same / d. h, z.

When a button 2 is pressed, the contact arms 6 of the contact element 1 rest against the peripheral contact fields 3 ″ assigned to the button. When the button is pressed further, the center area 5 of the snap disk forming the contact element ^{1 swings through and automatically engages with the center contact 3 1 in the last approach area} A connection is thus created between the input rail 4 'and the output rails 4, the peripheral contact fields 3 ″ of which are conductively connected to them through bores 8. When the button 2 is released, the contact element 1 is at a distance from the contact field doors 3 ¹ and 3 ″.

In the device according to the invention, a coded signal is generated by pressing a button. The coding is determined by making the holes 8. This results in a large number of possible combinations, so that a great many codes can be defined. A downstream evaluation electronics can therefore be omitted. The device is furthermore flexible in that the number and arrangement of the bores can easily be varied according to plan, even by less qualified workers. The keypad can therefore be adapted to all needs without major development costs. Overall can be of an excellent Solution of the pending problems are discussed «
