る。[Detailed Description of the Invention] The present invention relates to an improvement of a small switch. In conventional small switches, a movable contact and a converter molded from synthetic resin are housed in the lower end of the switch case, which is molded from synthetic resin and includes a support and fixed contacts, and the opening is covered. When the converter is rotated by operating the actuator of the switch, in which an actuator molded from synthetic resin is fitted onto the protrusion of the converter from the cover, the opening formed in the cover will open the switch. This is an opening with a gap necessary for the child's protrusion to rotate. Therefore, there is a drawback that dust enters through the gap, causing poor contact and poor insulation of the contacts, resulting in a decrease in performance.
