Abstract

A low cost, vibration resistant high frequency switch includes a conductive housing having bores for receiving a center probe, first and second cantilevered side probes, a floating center contact and a dielectric control rod. The center probe includes an axial bore in one end which loosely receives a first end of the low mass, wire shaped axially extending center contact. Adjacent the opposite, second end of the center contact, free ends of the side probe are spaced in a longitudinal direction perpendicular to the axial direction and extend from opposite directions into overlapping relationship with the floating center probe positioned therebetween. A solenoid controls the dielectric control rod which engages the center contact approximately midway along its length to selectively force the second end into engagement with the first or second side contact while maintaining engagement between the first end of the center contact and the center probe.
