METHOD AND APPARATUS OF MANUFACTURING RELAY

摘要

PROBLEM TO BE SOLVED: To provide method and apparatus of manufacturing a relay that enabled to adjust an electric property of the relay by regulating bending of a contact spring member using plastic processing without contact and that enables such an adjustment in a micro-relay. SOLUTION: A laser 1 is irradiated to a contact spring member 2 in the optimized laser energy condition, and as it generates temperature differences between a front surface and a rear surface of the contact spring member 2 in laser irradiation position and then plastic deformation is performed toward the side of lower temperature at these temperature differences, it can adjust the electric property of the relay by adjusting the bending of the contact spring member 2.
