Abstract
A system for setting in particular the rotor (2) of a coaxial or waveguide switch in n possible locking positions S.sub.1, S.sub.2, S.sub.3, . . . has an axially staggered drive on one side and on the opposite side a locking means (6, 7, 8/9, 10/11, 12). On the side facing the stator, the drive (3, 4, 5) has a drive winding composed of the drive coils (5) connected to only one pair of conductors by means of which a current of a determined polarity is supplied to the drive winding (5) and which turns the rotor (2) in the direction of the n locking positions S.sub.1, S.sub.2, S.sub.3, . . . by means of magnetic forces. The main purpose of the locking means (6, 7, 8/9, 10/11, 12) is to turn the rotor (2) into the exact locking position and to maintain it in that position.
