Summary:PROBLEM TO BE SOLVED: To provide a push switch for a vehicle, used mainly for lighting on/off control or the like of a stop lamp for an automobile, capable of obtaining a stable contact, and to provide its manufacturing method. SOLUTION: The push switch for a vehicle is structured by providing a plurality of fine coarse parts 13B, 14B by arc between contacts on the surface of a fixed contact 13 and a movable contact 14 coming in and out of touch with each other according to an up-and-down movement of an operating body 2, so that contact is made at a number of points on the contact surface due to the plurality of fine coarse parts 13B, 14B to increase contact pressure for each point and to make up a multi-point contact with a large contact pressure. Therefore, a stable contact can be obtained even in case an oxide film or the like is generated on the contact surface. COPYRIGHT: (C)2005,JPO&NCIPI
