Abstract

PURPOSE:To apply the waterproof and dustproof process perfectly, by inserting a plastic cover case in a metal mold; filling, heating, and pressurizing molding an unvulcanized rubber; and applying a bonding molding unitary process to give a dome form and a quick function to the cover case. CONSTITUTION:A contact 13 to form a dome 12 to be a switch is provided to a metal mold. And, when a loading member 8 for inserting a plastic cover case is molded, a plastic cover case surface rubber flowing preventive projection 9 is provided around the hole of a plastic cover case 14 in order to prevent the flowing out of the rubber to the surface of the plastic cover case 14. That is, the plastic cover case 14 is inserted to a metal mold, and an unvulcanized rubber is filling, heating, and pressurizing processed, and a bonding molding unitary process is applied to the opening part of the cover case to give a dome form and a quick function to the cover case 14.

2. Description of the Related Art As is well known, the structure of a button switch is such that a plastic cover case (FIG. 1) 1 and a rubber contact (FIG. 1) 2 (the key top portion is provided on the rubber contact and the key is exposed on the front surface and used as it is as a button). It consists of a plastic key button (Fig. 1) 3 and a printed circuit board (Fig. 1) 4, but dust or water gets into the gap between the plastic case and the rubber contact or the plastic key button that covers it. In particular, when drinking coffee such as sugary drink coffee or tea spilled, it causes a big defect that the sticky rubber contact does not function even when dried. There has been a strong demand for solving these problems in the era when life waterproofing is common sense for operation switches of home electric appliances, office automation equipment, precision equipment and the like.
