| 摘要 | PURPOSE:To obtain a key input part having an excellent characteristics, by inserting an elastic metallic thin plate on which plural key inputting movable contacts are formed, into a frame of an electronic apparatus made of an insulating high polymer. CONSTITUTION:A metallic thin plate 1 is formed by etching, pressing, etc., from a metallic material abounding in elasticity, such as phosphor bronze, stainless steel, etc. Plural semi-spherical dome parts 1a are formed toward the upper direction, on a key input part of this thin plate 1, and a recessed part 1b which projects downward on the contrary is formed in the center part of the dome part 1a, namely, the top part, respectively. This recessed part 1b constitutes a contact part of a key movable contact. On the other hand, as for a frame 2, when ABS resin, styrol resin, etc. are used as its material, the thin plate 1 is insert molded by injection molding. In this way, it is possible to obtain a key input part which decreases the number of parts, is assembled easily and is excellent in its operability. | ||||||
