Abstract
A sealed push-button switch which includes a switching mechanism including a terminal, a case including a space for housing the switching mechanism, and a base which is fixed to the case. A frame for housing the terminal is fixed to the base, and a melted resin material is injected into the frame and set to fix the terminal. When the melted resin is injected into the frame, the air in the case is heated and made to expand by the resin. However, the expanded air leaks out through an air passage which is formed through the case of the base. Air bubbles are accordingly prevented from developing in the resin.
