Abstract: A silver contact structure for conductive blades aims at providing an increased contact area between a silver contact and a conductive blade so that the silver contact may be fixed more securely without breaking off. The conductive blade has a fastening section running through which has a non-circular and irregular cross section to increase the horizontal frictional force so that the silver contact is less likely to break off and may result in a longer service life. The contact area between the silver contact and the conductive blade also increases, thus enhancing the heat dissipation.
