Abstract
A miniaturized high frequency switching device is capable of giving an optimum over-all impedance over the length of a signal path while compensating for inevitable impedance variation seen in a particular segment of the signal path. The switching device includes a contact block having fixed contacts and a movable contact. The fixed contacts and the movable contact are surrounded by an electromagnetic shield which is supported on a conductor base to be grounded therethrough for isolating the current path from a surrounding electromagnetic field. The fixed contacts are formed respectively on one ends of terminal pins provided for electrical connection to an external load circuit operating on high frequency signals. The terminal pin extends through an insulation ring fitted in the conductor base so as to be electrically insulated therefrom and form the signal path flowing a high frequency current. An impedance compensating structure is provided in the contact block for differentiating a first impedance at a first segment of a limited length along the terminal pin from a second impedance inherent to a second segment immediately adjacent the first segment so as to give a target over-al…
