After inserting a movable lever with a movable contact and holding it rotatably, the cam support shaft is inserted into the through hole of the switching cam. After the slit opens slightly due to elastic deformation, the shaft engagement protrusion opens into a ring shape. When the switching cam is fitted into the groove, the interval between the slits narrows, and the switching cam is rotatably held on the cam support shaft. After that, it is only necessary to lock the switching spring between the switching cam and the movable lever, and the assembly becomes extremely simple. The shape of the cam support shaft is also relatively simple and can be easily made.
