Rotary waveguide switch having magnetic means for an accurate positioning thereof

摘要

A waveguide switch includes housing walls defining a switch housing; at least two waveguide terminals provided in the housing walls; a rotor supported for rotation in the housing; at least one waveguide element contained in the rotor for coupling to one another at least two waveguide terminals in a predetermined angular operating position of the rotor; a motor for turning the rotor into the vicinity of a desired operating position and blocking assembly for arresting the rotor in the desired operating position. The blocking assembly and the rotor include a magnetic arrangement for turning the rotor from the vicinity of the desired operating position into the desired operating position by magnetic attraction.
