Push or slide key assembly for receiving devices of the Communications engineering.

The present innovation relates to a printing or Sliding key assembly for receivers in communications engineering with several frequency ranges, whereby the pressure resp. A part that can be adjusted by several angular positions is assigned to the slide button, by means of which one of the frequency ranges can be selected and can be switched on when the button is pressed and with each a tuning member assigned to a key, which can be coupled to a tuning button common to all when the key is pressed and when the tuning button is turned, a member which actuates the tuning element and thus influences the vote is adjustable.

In such known push or slide key units with so-called central voting, for example, everyone is Push button assigned a tuning spindle on which a gear is axially displaceable and rotatably mounted and that when Pressing the assigned button in operative connection with the skimming spindle comes. As a result, the spindle of the pressed button is operated when voting by a special tuning button and moves a displaceable part located on the spindle, which in turn moves a tuning member.

It is also known that each pushbutton has a coupling mechanism to assign a rotary potentiometer, which is similar to that in the aforementioned case when the button is pressed is coupled to the tuning button and can therefore be adjusted by this.

With these previously known push or slide key aggregates th, the frequency range switchover or the selection of the frequency range is carried out using the button itself or the key button has a rotatable sleeve which encloses a push button and this sleeve serves as a frequency range switch. In both cases it is possible to design the pushbuttons as round pushbuttons. Will however

desired) to use a square push button, then one is Rotation of the outer sleeve-shaped part to select the frequency range not possible anymore. It is therefore the purpose of the innovation to find a way to make a square push button like this to train that nevertheless with it a choice of frequencies and it is possible to switch on the frequency range by pressing the button.

According to the innovation, this is achieved by switching the frequency range effecting adjustable part is enclosed by the pushbutton transmitting part and that he is on the front side has an actuating element. This arrangement according to the innovation of the frequency range switching causing part within the pushbutton part, the actual key part no longer needs to be rotated, so that the push button part can have any square shape.

Further advantageous details of the innovation are given below with reference to an exemplary embodiment illustrated in the drawing described «

With 1 is part of a tuning element, for example a tuning spindle referred to, which is mounted in a housing 2. The tuning spindle 1 is by a push button that consists of a preferably square or quadrangular key part 3 and one within the same between the tuning spindle 1 and the key part 3, adjustable to different angular positions Part 4- consists, displaceable in the axial direction.

The push button is in its rest position by a compression spring ρ iß held, on the one hand against the inner face of the adjustable part 4 and on the other hand against the outer wall of the housing 2 is supported. The adjustable part 4 is located with a nose G, which in the example also serves as a locking member, at notches 7 of the key part 3. The notches 7 are used for rasterization of the adjustable part 3 in different angular positions. On the other hand, the rest position of the tuning spindle 1 is limited by that behind the vertical wall of the housing 2 between two snap rings 8 a sole plate 9 is provided, which rests against the wall of the housing 2 from behind. The disk 9 is with the key part 3 connected in that the key part 3 tabs

10 are attached, which reach through the housing wall 3 and reach through slots 11 of the disk 9, the locking fingers 12 of which engage behind the disk 9. For better locking of the tab 10 in the slots 11, the tab end is expediently provided with a slot so that resilient legs arise that allow elastic deformation of the same, so that the connection of the key part 3 with the disc done by a snap connection.

To actuate the adjustable part 4, an actuating member, for example an actuator, is expediently in its front side 13 Slot 14 is provided.

In order to achieve a certain damping when the pushbutton recoils the disk 9 is expediently made of an elastic material, so that a damping occurs in the event of a kickback is achieved.

The tuning spindle 1 can in a known manner with a Thread 15 be provided on which a traveling nut 16 axially slidably but non-rotatably applied. An actuating element 17 can be moved via this traveling nut again a variable capacitor or a potentiometer for tuning can operate a voting unit. The operation the tuning spindle 1 takes place in this example as is explained with reference to the introduction to the description, namely by gears are provided and a common tuning button is available.

The latching and mutual unlatching of the pushbuttons is carried out by a latching rocker 18, which is by a compression spring 19 on a Locking bolt 20 rests and can engage in a locking groove 21 in the pressed state.

The nose 6 is expediently designed in such a way that it is connected to a pivotable or displaceable actuating member 22 can cooperate, which in turn can directly or indirectly actuate a frequency range flihalter, which for the sake of clarity s reasons not explained in detail uad is designated.

The actuating member is, for example, expediently provided in a manner known per se with a step-shaped part 23, see above that depending on the angular position of the adjustable part 4, the actuating member 22 can assume a different position. Here-
