Abstract
A multiposition microwave switch with a cavity comprising a center and a plurality of radial portions with acutely extended legs. The central coaxial connector selectively communicates with one of a plurality of peripheral connectors, the others being terminated by impedance matching resistors housed in the legs and isolated and shielded from the central connector. The cavity is housed beneath a plurality of pivotal rockers responsive to magnetic actuating means. First and second conductive reeds are spring loaded in the radial portions and legs, respectively, of the cavity and are mechanically responsive to the rockers such that when a first reed is conducting between central and peripheral connectors, its complimentary second reed is shorted to the housing. When the first reed is shorted to the housing, its complimentary second reed terminates the peripheral connector by conducting between it and the resistor.
