第１項または第２項記載の小型スイツチ。[Claims for Utility Model Registration] (1) A contact electrode made of conductive metal is provided at one end of the cylinder, and a movable piece made of conductive metal with a plurality of sharp protrusions formed at one end is attached to the cylinder. The protrusion is arranged so as to be movable in the body and can come into contact with the contact electrode, and a coil spring elastically biases the movable piece in the contact direction, and an operating rod made of an insulating material is attached to the cylindrical body. The movable piece is fixed to one end on which the protrusion is formed so as to protrude from one end, and when the operating rod is pressed, the movable piece is separated from the contact electrode against the elasticity of the coil spring. 1. A small switch, characterized in that the electric circuit between the movable piece and the contact electrode is cut off when the movable piece is moved. (2) A cylindrical body with a bottom at one end is formed of conductive metal, and the bottomed part is used as a contact electrode, and the operating rod is made to protrude from a through hole bored in the bottomed part. Scope of claim for utility model registration No. 1
Small switch mentioned in section. (3) Utility model registration claim 1 or 2, characterized in that one end of the movable piece is bored into a conical shape in the axial direction and then cut to form a plurality of sharp protrusions. A small switch.
