Abstract

A small switch having an easy-to-use push button (2) with a long stroke and a high positioning accuracy and capable of reducing a cost, wherein a sector-shaped shaft (17) as a first projected part formed on a circular second projected part (19) provided on both side faces of the push button (2) is fitted into a semi-circular hole (16) provided in a body (1) and the second projected part (19) is fitted into a recessed part (20) provided in the inner surface of the body (1) and the semi-circular hole (16), and the push button (2) is rotated about the center (13) of the shaft (17) until the wall surface (17a) of the shaft (17) abuts on the end edge of the semi-circular hole (16), whereby, since the portion of the body (1) near the end edge of an opening can be used for holding the pivot of the push button (2), the necessity of fixing hardware is eliminated, and the stroke of the push button (2) can be increased by fitting the shaft (17) of the push button (2) into the semi-circular hole (16) to form a support shaft and reducing the opening angle of the shaft (17).
