ABSTRACT:
A switch is comprised of at least one leaf-like springy fixed contact, a movable contact, a supporting member for supporting the fixed contact and a positioning member for positioning the free end of the fixed contact. The leaf-like fixed contact is fixed by the supporting member at a position close to one end of the fixed contact, and is biased by the positioning member at a position close to the other end. Thus, the free end of the leaf-like springy fixed contact is placed at a position by its function of urging the positioning member.
