Definitions

  • the invention relates to a key-operated electrical switching device with the features of the preamble of claim 1.
  • a switching device of this type is known from US Pat. No. 4,331,013 and fulfills the task of switching the circuit of the electrical system of a motor vehicle against theft.
  • a number of magnetic switches are arranged at a uniform distance from one another in the housing of the device, of which magnetic switches selected only according to a coded scheme by the electrical switching scheme are to be switched on in order to establish the desired electrical connection, so that permanent magnets invisibly enclosed in the key body at a suitable position must be provided.
  • this connection remains interrupted.
  • the invention has for its object to find a switching device according to the preamble of claim 1, the simple and inexpensive to manufacture and space-saving structure allows a reliable and confusion-free optional switching of different electrical connections by different keys. This object is achieved on the basis of the characterizing features of patent claim 1.
  • the switching device according to the invention is particularly suitable for the optional activation of different counters for the amount of value consumption of an electronically controlled franking machine, so that the individual amount of value consumption of different users, who each have a different key, can be identified.
  • the electrical switching device shown overall in FIG. 1 is fastened to a housing plate 1 of a franking machine (not shown in more detail).
  • a housing plate 1 of a franking machine for this purpose, three smaller recesses or openings 2, 3, 4 for the engagement of extensions 5, 6, 7 of a steel housing 8 of cross section with a U-shaped cross section of the switching device are provided in the housing plate 1, as well as a circular opening 9 through which the one shown in FIG. 6.7 shown, the key guide inner housing 10 is inserted.
  • the switching device is held on the housing plate 1 by a rosette 11 molded onto the inner housing 10 rests along the edge of this opening 9 on the outer surface of the housing plate 1 and an extension 12 is formed on the rear end of the inner housing 10, which with a rear transverse wall 13 of the steel housing 8 is connected.
  • this extension 12 extends through a correspondingly shaped opening 14 and carries a locking pin 15 which engages through a transverse bore 16 of the extension provided behind the transverse wall 13 and thus rests on the outside of this transverse wall. After removing this locking pin, the entire switching device can consequently be lifted off the housing plate 1, and the switching device can be assembled simply and quickly.
  • plate extensions 27, 28 provided on the front and rear ends of this circuit board 20 engage in correspondingly shaped depressions or openings 29, 30 of the housing plate 1 and the transverse wall 13 when the steel housing 8 is mounted on the housing plate 1 in the manner described above by means of the inner housing 10.
  • the key 32 like the inner housing 10 made of plastic or another material not influencing magnetic fields, consists of an elongated plate with flat outer surfaces and closes at least one pin-shaped permanent magnet 41 to 45 and, in the case of a number of five magnetic switches 21, in an invisible manner to 25, a maximum of four permanent magnets 41 to 43 and 45.
  • the key has 32 receiving bores A, B, C, D for the pin-shaped permanent magnets, which extend transversely to the longitudinal direction of the key in the key plane. After certain receiving bores have been filled in accordance with the code scheme shown in FIG. 2, they are tightly closed by a common locking web 47 by welding it to the key body.
  • the flat outer surfaces of the key body can, for example Wear illustrations or characters so that it can also serve as an advertising medium like a key ring.
  • the code scheme reveals that each of eight different keys with the numbers 0 to 7 in hole D, which is located at the rear end of the key 32, has a magnet 45, in accordance with the condition provided in the code signal processor C that the switching device is connected to the counter Z of the franking machine only makes an electrical connection if the rearmost magnetic switch in the key insertion direction is also actuated by the magnet 45.
  • the rearmost magnet 45 is in this end or stop position of the key 32 to the rear most magnetic switch 25 in the shifted switching position, while the remaining magnets 41 to 43 or the mounting holes A, B, C provided for them are the associated Magnetic switches exactly, ie with the shortest distance.
  • the aforementioned offset switching position corresponds to that position of the magnet 45 in which the magnetic switch 25 is just just being reliably switched by the force of the magnetic field of the magnet 45.
  • This shifted switching position results, for example, from the fact that a greater distance is provided between the rear magnetic switches 24 and 25 or also between the magnetic switches 23, 24 than between the three front magnetic switches 21 to 23, while only between the penultimate and last magnets 43 and 45 there is a distance that is twice as large as the distance between the magnets 41 to 43 due to the empty space between them.
  • the distances between the magnets 41 to 43 or their receiving holes and correspondingly the distances between the magnetic switches 21 to 23 are each 7 mm while the distance between the three rear magnetic switches 23 to 25 is 8 mm and the distance between the two rear magnets 43.45 is 14 mm.
  • Securing an exactly predetermined switching position of the key 32 in the key receiving hole 18 is of great importance for a reliable function of the switching device according to the invention due to the sensitive magnetic switches (reed contacts) and the scatter of the magnetic fields of the various magnetic fields, which also influence one another.
  • the magnets In order to prevent with greater certainty that the magnets influence one another via their fields, or to allow a more compact arrangement of the magnets, they can preferably be arranged alternately with opposite polarity, as shown in FIG. 1, the reverse arrangement of the magnet 45.
  • the switching device thus has a steel housing 8 with ferromagnetic properties, which encloses the magnetic switches 21 to 25 on three sides due to its U-shaped cross section.
  • the penultimate position i.e. In front of the rearmost magnetic switch, a magnetic switch 24 serving as a locking switch is provided, when the magnetic signal switch C is closed, a locking signal is emitted.
  • This blocking magnet switch 24 is used to operate the magnet switch 25 during an unauthorized attempt by means of a third-party magnet, the actuation of which is necessary for each main electrical circuit of the device, and the blocking magnet switch 24 is also actuated.
  • the code scheme shown in FIG. 2 for keys with the key numbers 0 to 7 shows the occupation of the receiving holes A, B, C, D provided in the key 32 by magnets and their polarity by specifying the south or north poles S and N, respectively one side of the key 32 is directed.
  • a key with the number 5 in the holes A, C and D has a magnet 41, 43, 45 with the same polarity of the magnets in the holes A and D.
  • certain signal combinations of the magnetic switches 21 to 23 corresponding to the code are and 25 are stored, when they are fed to the code signal processor C due to the switching of a specific combination of magnetic switches 21 to 23 and 25 in accordance with the respective key code, an electrical switching connection to the consumer, ie in the present example for the counter Z of a franking machine.
  • a switching device has many advantageous possible uses due to its simple structure and reliable function, e.g. also as a locking device on doors or container lids that are heavily stressed by the weather, since no impurities or moisture can penetrate to the electrical switching connections via the key receiving hole 18 and these can also be completely encapsulated in a water-protected manner in a simple manner.
  • the switching device is arranged on a region of a housing plate 1 which runs horizontally or inclined so that there is a downward inclined or vertical orientation of the key guide, i.e. of the inner housing 18 results.
  • a housing plate 1 which runs horizontally or inclined so that there is a downward inclined or vertical orientation of the key guide, i.e. of the inner housing 18 results.
