PURPOSE:To make it possible to select three kinds of connections among four fixed terminals by simple constitution, by arranging one contact in the center of rotation. CONSTITUTION:The coaxial switch consists of four coaxial connectors 1 to 4 constituting external connection termianls, housing 7 holding fixed contacts 11 to 14 connected to the center conductor, rotary disc 8 composed of an insulating plate with conductor parts 5 and 6 provided at its surfaced meeting those contacts 11 to 14, and driving part 9 driving disc 8; contact 11 of connector 1 is provided at the position which corresponds to the center of disc 8, and other contacts 12 to 14 are arranged symmetrically on the same circumference around contact 11 at an interval of 120 deg.. In this constitution, three kinds of connections (a) to (c) allowing a connection between two out of four contacts 11 to 14 can be obtained by turning disc 8 120 deg. by 120 deg.. |
