Abstract
A microwave multi-port switch has three operating positions and three RF paths. Six peripheral contact junctions are provided adjacent corners of a hexagonal cavity in an RF body and a common contact provided at the cavity center. Six reeds bridge over in and out of contact with adjacent ones of the peripheral contacts and six reeds extend between and in and out of contact with the peripheral contacts and the common contact. Reeds are actuated by movement of a coil-driven rocker through three actuating mechanisms, including a center post, at three levels above the body. The mechanisms include radially extending leaf springs, an actuator loosely keyed to the center post and a pivoted leaf spring movable by rocker tilting depressing the actuator, the leaf springs and fixed dielectric posts extending upwardly from the reeds.
