Document Type and Number:
WIPO Patent Application WO/2011/045943
Kind Code:
A1
Abstract:
Provided are electrical contacts for relays and a manufacturing method thereof, 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 made easy to make, and a high electrical contact reliability is achieved. The rivet-shaped electrical contacts (1) for relays, which are used as movable contacts for the relays, have a heavy-load contact section (2) formed of a first silver-oxide type contact material, and a light-load contact section (3) formed of a second silver-oxide type contact material, and the first silver-oxide type contact material is made to be harder than the second silver-oxide type contact material.
