To simplify the design of a rotary actuator, in particular for an &ldquo;R&rdquo;-type waveguide switch, having a permanently magnetized rotor and a plurality of stator windings surrounding the rotor in a rim-like fashion, for generating magnetic fields which place the rotor in one of a first plurality of positions, it is proposed to finish the actuator with elements for exerting a corrective torque on the rotor, the elements placing the rotor, in the currentless state of the stator windings, in a target position of a second plurality of positions, each position of the first plurality having assigned to it a target position.

Rotary actuating drive and rotary switch

A coaxial switch for making or breaking an electric contact between inner conductors of coaxial cables includes a wall component defining an inner space into which end portions of the inner conductors project and a contact guiding assembly including first and second parallel-spaced spring diaphragms each having an outer peripheral portion and a mid portion; one portion being fixedly held and the other portion being displaceable in a switching direction towards or away from the inner conductor ends. The contact guiding assembly further has first and second leaf springs provided in the diaphragms. Each leaf spring has a first segment connected to a respective spring diaphragm for hinging displacements relative thereto; and a second segment hingedly connected to the first segment. The first and second segments are oriented such that motion components of the two segments transverse to the switching direction are opposite one another. A support element is mounted on the second segment and passes with a clearance through an aperture in the wall component and projects into the hollow space, and an electric contact element is carried by the support element for making or breaking electric contact between the inner conductors. A drive arrangement displaces the contact guiding assembly in the switching direction.
