摘要： In a manufacturing method of a push-button switch, a key-top end of a pressing element 25 is inserted into a lower-mold recess for the pressing element, which is provided in a surface of a lower mold. A reinforcing plate 28 is placed in the lower mold so that the pressing element 25 extends through a plate through hole of the reinforcing plate 28. An upper mold and the lower mold are moved toward each other so as to insert the other end of the pressing element 25 into an upper-mold recess for the pressing element, which is provided in a lower surface of the upper mold. A liquid silicone rubber 27, which contains a component that does not adhere to the upper and lower molds but adheres to the pressing element 25, is introduced into a cavity. After the upper and lower molds are pressed and held at a predetermined temperature for a predetermined time, the upper and lower molds are opened to remove a molded product in which an intermediate portion in an axial direction of the pressing element 25 is supported in the plate through hole by the silicone rubber 27. A back surface of a key top 26 is attached to the key-top end of the pressing element 25 in the molded product. Thus, the pressing element and the elastic member are easily and reliably integrally molded by using the elastic member, and durability of the push-button switch is improved.
