Definitions

  • the invention relates to a telephone set with a dial key set according to the preamble of claim 1.
  • a push button switch with many contacts is known, such as that used in telephones.
  • pushbuttons with a hat-shaped cross section are guided in the cover plate, the collar of the pushbutton limiting its stroke upwards by abutting the shoulder of the narrower hole in the cover plate.
  • the inside of the push button is hollow, the recess accommodates a helical compression spring, which is used for resetting. At its free end, the spring is connected to a plunger, which acts on the contact.
  • the latter is formed by a convexly curved disk or plate which snaps around at the push of a button and comes into contact with the contacts or conductor tracks of a circuit board underneath.
  • the object of the present invention is to provide a telephone set with a key set which is particularly protected against vandalism.
  • This task is solved by the features specified in the characterizing parts of the claims.
  • the dial button set of a telephone set, in particular a payphone is almost insensitive to the effects of blows, fire and liquids.
  • the solution can be used for all types of key sets, ie for key sets with foil contacts and for key sets with contact springs.
  • a version is specified in which commercially available key sets can remain unchanged and are nevertheless protected against damage of the type mentioned above.
  • a metal guide plate 1 which is provided with tubular, upwardly directed projections 6 at the locations of the keys, is placed directly on contact foils 13. Their number and stratification depends on the application.
  • the conductor tracks 7 of different foil layers face each other openly so that they come into contact when the respective key is depressed.
  • the plungers 5 are mushroom-shaped, with the curved roof 14 directed downwards against the contact foils 13 and the shaft 15 upwards.
  • One end of a helical compression spring 4 is plugged onto the latter, the other end of which is supported against the respective push button 3.
  • the push buttons 3 have a hat-shaped cross section.
  • the walls of the cavity 16 serve as a guide on the tubular extension 6 of the guide plate 1.
  • the cavity 15 forms the receptacle for the upper end of the helical compression spring 4, which causes the key to be reset.
  • the outer walls of the push buttons 3 are guided in corresponding openings 18 in a cover 2 which is placed on the guide plate 1.
  • the cover has pulled-down side walls 19 and stiffening ribs 20 between the keys, all of which end in the same plane and form the contact surfaces with the guide plate 1.
  • Their height also determines the stroke of the buttons because their push buttons 3 have a collar 21 at the open end, which strikes the cover 2 on the one hand and the guide plate 1 on the other hand.
  • Cover 2 and push buttons 3 are made of metal, preferably of an aluminum die-cast alloy. This makes the button set insensitive to blows and fire. It is also protected against liquids, since only small amounts can penetrate the push buttons, which then remain in the space between cover 2 and guide plate 1.
  • openings 8 are made, for example, at the butt joint between the cover and the guide plate. Since the key set is installed in oblique to vertical surfaces, it is sufficient if the openings 8 are provided on the underside.
