ABSTRACT:
A coaxial "M" switch having three coaxial input connectors (A, B, C) spaced evenly from each other, and three coaxial output connectors (1, 2, 3) identically arranged. In a cylindrical barrel embodiment (10) the input and output connectors are located at opposite ends of a cylindrical configuration. In one planar embodiment (30), the input and output connectors alternate with each other and define a hexagonal configuration (40). In another planar embodiment, the input connectors (A, B, C) define an inner triangular configuration (70) that is surrounded by the output connectors (1, 2, 3) defining an outer triangular configuration. In each embodiment, reeds are actuated in predetermined configurations to define three switch positions.
