Claims

[Claims for Utility Model Registration] (1) A through hole is formed in a converter provided below the push rod, a shaft is provided in the center between the left and right sides of the converter, and a shaft is provided approximately in the center of the switch base. A recess with a protrusion on the inside corresponding to the shaft is formed at the upper end of the protruding column, and the recess is engaged with the shaft so that the converter is tilted left and right when pressed by the push rod. A coil spring is arranged between the lower surface of the pressing side of the converter and the switch base, so that the movable contact piece provided on the side surface of the converter makes sliding contact with the fixed contact piece fixed to the switch base. further, a coil spring is disposed between the push rod and the upper end of the protruding column, and a hanging piece having a protrusion at the tip extending from below the push rod is disposed along the protruding column to pass through the converter. A small push button switch characterized in that the protrusion is arranged so as to be able to come into contact with a lower end engaging portion of the converter on the side opposite to the pressing side. (2) The small push button switch according to claim 1, wherein the bottom surface of the protruding support column and the substantially central portion of the switch base body are disposed in a concave-convex engagement manner.
