Abstract
A micro switch includes a fixed contact and a movable contact. One is made of silver-carbon sintered metal, and the other is made of a silver-metal oxide alloy. The silver-carbon sintered metal includes carbon powder particles sufficiently small in average size to be capable of plastic molding into a sintered metal. The contact made of the silver-carbon sintered metal is directly crimped onto a contact supporting plate.
