  • Patent number: 9105412
    Abstract: A rivet-shaped electrical contact for relay is used as a movable contact for the relay. The rivet-shaped electrical contact includes a heavy-load contact portion formed of a first silver-oxide type contact material; and a light-load contact portion formed of a second silver-oxide type contact material. The hardness of the first silver-oxide type contact material is set to be higher than that of the second silver-oxide type contact material.

  • Publication number: 20140201999
    Abstract: A method of manufacturing a composite contact in which a flange section with a large diameter at an end of a base part with a small diameter, the composite contact having: a contact section which is made from silver alloy into an upper-surface part of the flange section; and a leg section which is made from copper alloy by forming a large-diameter part so as to form a lower-surface part of the flange section is made integrally with the base part, having the steps of: a primary-forming process forging a copper-alloy wire and a silver-alloy wire having a smaller diameter than that of the copper-alloy wire in a hole of a forming die in a state of being butted to each other so as to form a primary-formed body including a silver-alloy part and a copper-alloy part so that the wires are bonded with each other.
