Abstract:
1. A method of manufacturing a push-switch for a vehicle comprising: embedding a fixed contact within a case formed in a substantially box shape with a top plate provided with an opening; providing a movable contact within the case so as to oppose the fixed contact and to engage with and separate from the fixed contact at both end portions thereof; accommodating an operating member within the case so as to penetrate the case at the opening, the operating member being configured to move the movable contact in the case; applying a predetermined value of voltage between the movable contact and the fixed contact in order to form a plurality of fine projections and depressions on a surface of at least one of the movable contact and the fixed contact by arcing discharges; and moving the operating member to have the movable contact engage with and separate from the fixed contact in a condition while keeping the voltage between the movable contact and the fixed contact applied.
