Description of the Related Art Generally, a push switch of this type has a very small length of at most 8 mm from the tip of an object detecting shaft to the other end of a housing. Therefore, the contact piece that comes into contact with and separates from the terminal in the housing as the shaft advances and retreats has a length of about 3 mm and a thickness of 0.1 mm or less.

もあった。In the conventional push switch of this type, the contact piece is formed in advance into a cantilever spring or a U-shaped spring by pressing and is incorporated into a molded shaft. There is a problem that the space for the fixed portion of the piece is required, and the span of the contact spring portion is shortened accordingly, so that an expensive metal material such as beryllium copper having excellent spring properties must be used.
Further, since the shaft and the contact piece are separate bodies, there is also a problem that another process such as crimping for integrating them into one is required.
