ABSTRACT:
A coaxial short-circuit device has an inner conductor which is surrounded by an outer conductor and is electrically connected to the latter by a shorting plunger. In order to allow the axial movement of the shorting plunger, the inner conductor accommodates a spindle which is connected in a force-locking manner to a first carriage arranged between the spindle and the inner conductor. A second carriage is arranged between the inner and the outer conductor and cooperates with the first carriage in such a manner that upon rotational movement of the spindle the first carriage is axially shifted along the spindle and this movement is transmitted to the second carriage and eventually to the shorting plunger which is connected to the second carriage in a force-locking manner. Transmitting the movement of the first carriage to the second carriage is provided by magnets respectively accommodated by the first and second carriages and polarized in an opposing manner so as to cause an attractive force between the carriages.
