Abstract

A microswitch in which a good snap action feeling is obtained and an operating stroke is enhanced is provided. A compression spring (26) is interposed between a movable member (18) and a swingalbe lever (23) which are respectively pivotally supported at close positions. The swingable lever (23) is operated by a push button (22) which is vertically slidable. Further, restricting plates (30, 31) to restrict the motion in the width direction of the movable member (18) are attached to the push button (22). A positioning member (36) to hold the swingable lever (23) to the position which faces the push button (22) when the microswitch is assembled is also provided.
