Abstract:
A high frequency relay comprising a contact base block having at least one pair of fixed contacts, at least one contact member with a movable contact, and an electromagnet for moving said contact member to open and close said pair of fixed contacts by said movable contact,wherein said contact base block comprises: a base having at least one pair of projections on its top surface, which is an injection-molded article of an electrical insulating material; first metal films formed as said fixed contacts on top surfaces of said projections; second metal films formed as connection terminals for outside devices on said base, each of which corresponds to one of said first metal films; connecting means for making an electrical connection between each of said first metal films and the corresponding second metal film; and a third metal film at least formed on the top surface of said base to provide electrical isolation from said first and second metal films, which works as electromagnetic shield means.
