Definitions

  • the invention relates to a key with a light indicator for keyboards in office and teleprinters, in which a side opening for a light-emitting diode is arranged on the front of the key button in the viewing area of an operator.
  • the object of the invention is, while maintaining the advantages associated with the use of a light-emitting diode, such as low power consumption, insensitivity to touch and good signal effect, to avoid the susceptibility to contact, even with frequent key presses, and to reduce the production outlay.
  • a light-emitting diode such as low power consumption, insensitivity to touch and good signal effect
  • the requirement is to be met that such a key with a light-emitting diode corresponds in terms of its dimensions to the normal keys used in the keypad.
  • the button should be usable either with or without a mechanical locking device.
  • a circuit board containing the plug-in device and the power supply for the light-emitting diode and blown into the button is provided in the button, that the power is supplied via flexible power supply cables, for carrying them out in the button socket, optionally with or without mechanical locking device is equipped, recesses are provided, and that the power supply cables are guided between the recesses and the circuit board in the form of an interlocked loop.
  • the opening in the button for receiving the light-emitting diode is arranged such that it lies in the operator's perspective. This has the advantage that the light display is clearly visible even in bright surroundings. Furthermore, there is the advantage that the surface of the button is available as a labeling surface and that the tip of the light-emitting diode does not appear to be a nuisance when the button is pressed.
  • the button with light indicator can be without and with a mechanical locking device of the switch position can be used.
  • the illuminated display is switched on and off each time a key is pressed using subsequent electronics.
  • the key has a mechanical latching device, by means of which the key is held in the switched-on position after it has been actuated. The unlatching. is then done by pressing the button again.
  • a button designed according to this embodiment offers the guarantee that a safe mechanical locking and unlocking is possible with relatively simple means.
  • the key shown in Fig. 1 consists of the button 1, the slide 3 protrudes into the key base 2.
  • the button 1 contains the circuit board 4, which is for example blown into the button 1.
  • the power supply for the light-emitting diode 5 takes place via the two flexible power supply cables 6, which can be mechanically soldered together with the light-emitting diode 5 in the printed circuit board 4.
  • the LED 5 is visible through a side opening of the button 1.
  • the entangled loop of the flexible power supply cable enables a sufficiently high number of operations to be achieved without the risk of a wire break.
  • the key base 2 has laterally known guide and holding devices, via which the key is inserted into a base plate and held there.
  • the power supply cables 6 are passed through the key socket 2 and connected to a keyboard circuit board 7.
  • the ends of the power supply cable are provided with a crimpable release pin, for example, which establishes the mechanizable solder connection to the keyboard circuit board 7.
  • a crimpable release pin for example, which establishes the mechanizable solder connection to the keyboard circuit board 7.
  • the button has a guide part 10 formed on the slide 3, and a coulisse lever which is rotatably attached on one side to the button base 2 8. At the end of the link lever 8 opposite the fulcrum 11, this ends in a guide pin 12 which is guided in a form-fitting manner in the guide part 10 when a button is pressed. Further details of the design of the guide part 10 will now be given in the following with reference to FIG. 2 in the description of the mode of operation of a latching or an unlatching process.
  • the guide pin 12 of the link lever rests on the guide bevel 13 of the guide part 10, as shown in FIG. If the button is now actuated, the guide part 10 moves downward and the guide pin 12 slides along the guide bevel 13 with simultaneous deflection about the pivot point 11 up to one. Groove 14, which forms an end stop, and into which the guide pin drops. This position of the guide pin 12 limits the depth of the button. If the button is now released, the guide pin 12 of the link lever 8 follows a guide edge 15 until it engages in a locking recess 16, thereby preventing the slide 3 from returning further. The button is mechanically locked in this position.
  • every normal button can be configured as a light button in the manner described. This ensures particularly economical production and the installation conditions for illuminated buttons are identical to those for normal buttons.
