Contact arrangement

摘要

An elastic member made of a metallic conductor is installed inside a main body. A contact head made of a conductor is pressed by a force exerted from the elastic member against an object to be contacted. The contact head is connected to a wire constituting a part of an electric conduction path. An insulator for breaking electric continuity between the elastic member and the contact head is inserted between the elastic member and the contact head. In addition to establishing electrical continuity with the object to be contacted using the wire and the contact head rather than the elastic member, the elastic member is insulated from the contact head and placed apart from the contact head to suppress parasitic capacitance between the elastic member and the contact head.
