Definitions

  • the invention relates to an electrical switching device according to the preamble of claim 1 or 2.
  • a switching device which serves to turn off a power line for a high-frequency attenuator via different damping elements.
  • it has an elongated switching element, which is movable transversely to its longitudinal direction by an adjusting element and is thereby brought with a contact surface at one end selectively out of contact or in contact with a mating contact surface.
  • the conduction of the electrical current at the contact surfaces is dependent inter alia on the contact surface and the mating contact surface. Impurities or particles can significantly affect the power line, especially if the impurities or particles are made of electrically non-conductive material.
  • Emissivity lines have e.g. several serially arranged four-pole switching devices with input and output side equal and constant characteristic impedance and each adjustable calibrated damping and thus also precise level.
  • a switching device of the type specified is in the GB 1 021 047 A revealed, see Fig. 4 and the associated parts of description.

  • a simple construction should be created.
  • the invention is based on the finding that in a switching movement drive of the switching element with magnetic and / or fluid forces there is no need for mechanical movement contact between the switching element and the adjusting elements and therefore in this case generated with magnetic and / or fluid forces switching movements of the switching element in this respect neither a sliding friction takes place still a resulting abrasion is generated.
  • the switching element is at least partially made of magnetic material
  • the adjusting elements are formed by magnets, wherein for a switching operation, the effectiveness of the magnet, which is arranged with respect to the mating contact element to be contacted on the opposite side, can be reduced or canceled in that the effectiveness of the magnet can be reduced or canceled by a fluid flow of a nozzle which is arranged on the same side and directed towards the side of the switching element facing it and is optionally switchable on and off.
  • one of the two magnets thus fulfills the switching function, ie the movement of the switching element towards the respective mating contact, and the contact holding function on the mating contact element, wherein the effectiveness of the magnet opposite the mating contact element to be contacted is reduced or eliminated.
  • This can be achieved for example by the fact that the opposite magnet is put out of action, for example, a solenoid is switched off or fed with less power, or the switching element with a magnetic force of the opposite Magnets, such as an electromagnet or a permanent magnet, exceeding adjusting force is moved to be contacted counter-contact element out.

  • the switching element As far as the mating contact element, there is thus neither a mechanical sliding friction nor a resulting abrasion, so that the electrical contact remains unimpaired in this respect.
  • the invention is characterized in each case by a simple configuration, which can be realized in a small construction, because it requires no mechanical connection between the switching element and the adjusting elements. Due to the lack of a mechanical connection, the embodiments according to the invention are variable and adaptable with respect to the distances between the switching element and the adjusting elements, so that they can be integrated into existing constructions in a simple and advantageous manner.
