PURPOSE:To improve the contact adhering tendency and enhance the reliability by forming an electric contact consisting of Pd-Ni-Fe alloy with Pa as main component on a base consisting of a magnetic metal material. CONSTITUTION:A reed (base) 11 of a reed switch consists of a magnetic metal material (Fe-Ni alloy), and an electric contact 12 formed at the tip of the reed switch 11 is constructed by heat diffusion of Fe of the reed on Pd-Ni alloy, and Fe of the reed 11 is formed on an Ni layer 13 heat diffused. Oxidated iron 14 dispersed on the surface course of the contact 12 is obtained by oxidating Fe dispersed on the surface course of the contact 12. |
