Claims

[Claims for Utility Model Registration] (1) A conductive constriction having an axial hole is formed inside the center of a conductive cylindrical body, and a press made of an insulating material is formed on the opening side of one end of the cylindrical body. The member is fitted so as to be movable in the axial direction without slipping out, and the pressing member is elastically biased outward by a first coil spring to push the member toward the other end opening of the cylindrical body. A conductive movable piece is movably disposed so as to be able to come into contact with the narrowed part by a supporting member made of an insulating material but not to come into contact with the inside of the cylindrical body, and this movable piece is moved to the narrowed part by means of a coil spring. The movable piece is separated from the narrowed portion by the pressing operation of the pressing member in the axial direction against the elastic force of the second coil spring, and the movable piece is separated from the tube. A small switch characterized by being configured so that the electrical circuit with the body is cut off. (2) The small switch according to claim 1, wherein the narrowed portion is formed by disposing a conductive washer inside the central portion of the cylindrical body. (3) Utility model registration claim 1, characterized in that the inner protrusion of the pressing member is configured to freely pass through the hole of the narrowed portion and press the movable piece.
A small switch according to any of paragraphs 1 and 2. (4) The small switch according to any one of claims 1 to 3 of the utility model registration claim, characterized in that a plurality of protrusions are formed on either the narrowed portion or the contact surface of the movable piece. . (5) A conductive contact portion is disposed at the inner tip of the pressing member, and when the pressing member is pressed, the contact portion comes into contact with the movable piece, and an electric circuit between the movable piece and the contact portion is established. A small switch according to any one of claims 1 to 4 of the utility model registration claim, characterized in that the switch is configured to be electrically conductive. (6) The small switch according to claim 5, wherein a plurality of protrusions are formed on either the contact portion or the contact surface of the movable piece.
