ABSTRACT:
A silver contact fixing structure for conductive blades aims at providing a retaining force on a silver contact so that the silver contact is more secure and does not break loose when subject to striking. The silver contact is built in a fastening section formed on a conductive blade. The fastening section has at least two fixing zones connecting to each other and a bucking end adjacent to the fixing zones to increase the retaining force between the silver contact and the conductive blade so that the silver contact does not break loose easily thereby increasing the service life thereof.
