Abstract:
A high frequency switching device including a contact block, said contact block comprising:at least one pair of fixed contacts each formed on one end of terminal pins;a movable contact which is driven to close and open a path between said fixed contacts;a conductor base of electrically conductive material having insulation rings each passing through each one of said terminal pins to locate said fixed contacts upwardly of said conductor base in an electrically insulating relation thereto, said terminal pins and said movable contact being cooperative to define a signal path flowing a high frequency current;an electromagnetic shield upstanding from said conductor base to enclose said fixed contacts and said movable contact, said shield being electrically connected to said conductor base;wherein said contact block includes an impedance compensating means for differentiating a first impedance at a first segment of a limited length along said terminal pin from a second impedance inherent to a second segment of a limited length aligned immediately adjacent to said first segment along said terminal pin so as to give a target over-all impedance, which is between said first and second impedance, over the full length of each said terminal pin.
