Abstract: A microwave multi-port switch (25) has three operating positions and three RF paths (J3-J4, J2-J5, J1-J6). Six contact junctions (J1-J6) are provided adjacent corners of a hexagonal cavity (26) in an RF body (27) and a common contact (17) provided at the cavity center (36). Six reeds (15a-f) bridge over in and out of contact with adjacent ones of the peripheral contacts (J1-6) and six reeds (19a-f) extend between and in and out of contact with the peripheral contacts (J1-6) and the common contact (17). Reeds (15a-f) are actuated by movement of a coil-driven rocker (80) through three actuating mechanisms (44), including a center post (36), at three levels above the body (27). The mechanisms (44) include radially extending leaf springs (35), an actuator (50) loosely keyed to the center post (36) and a pivoted leaf spring (35) movable by rocker (80a) tilting depressing the actuator (50), the leaf springs (35) and fixed dielectric posts (43) extending upwardly from the reeds (15a-f).
