ABSTRACT:
A microwave switch employs a slender reed contact which bridges across a pair of microwave probe ends to permit microwave signals to pass therebetween. The reed contact is connected to one end of a dielectric actuator post and a permanent magnet is affixed to a headed end of the post, a medial portion of the post extending through a microwave housing wall. A cup-shaped bushing preferably made of a polyimide plastic and a lubricating filler such as graphite or molybdenum disulfide, surrounds the edge and bottom periphery of the magnet and the post head and reciprocates on an inner periphery of a steel ring clamping an iron washer in a housing wall counterbore. The magnet is statically magnetically attracted to the iron washer moving the attached post and reed contact into bridging contact with the microwave probes to form a path for microwave signals between the probes. A solenoid is positioned above the permanent magnet. Actuation of the solenoid and its production of a dynamic magnetic field overcomes the static magnetic field and pulls the magnet from the iron washer moving the attached post and reed contact away from contact with the probes thus interrupting microwave signal transmission between the probes.
