Microwave switch

Abstract

A microwave switch provides a random selection drive for selectively one or more reeds which are movable by an actuator to electrically bridge across a pair or pairs of microwave connector contacts. The preferred embodiment of the drive employs at least two actuators, normally three, in the form of cantilevered leaf springs, which are mounted at different levels or parallel plane in a drive body. Respective ones of the actuators are displaced by the rocking action of a wobble plate or rocker movable by repelling and attraction forces provided by a series of spaced magnetic coils spacedly mounted on the drive body. Integral pusher arms of various lengths extend from the bottom of the wobble plate with their distal ends terminating variously at the same different levels in which the leaf springs extend. Rocking of the wobble plate to one of three selected positions displaces a particular leaf spring which in turn depresses one or two selected reeds into bridging contact with a pair or pairs of selected microwave connector contacts. An indicator function is provided with respect to each leaf spring which indicates which pair(s) of the microwave connector contacts represent a closed RF path.
