ELECTRICAL CONTACT FOR RELAY, AND MANUFACTURING METHOD THEREOF

摘要

[Problems to be Solved] Provided is an electrical contact for relay and a manufacturing method for the same, wherein, when different electrical contact characteristics are required for opening/closing two electrical circuits, an optimum combination of contact materials in accordance with the states of each of the electrical contact loads is readily made, and high electrical contact reliability is achieved. [Means to Solve the Problems]A rivet-shaped electrical contact for relay (1), which is used as a movable contact for the relay, has a heavy-load contact portion (2) formed of a first silver-oxide type contact material, and a light-load contact portion (3) formed of a second silver-oxide type contact material, and the hardness of the first silver-oxide type contact material is set to be higher than that of the second silver-oxide type contact material.
