<p>The present invention provides an illumination key and a method of making such illumination key, which makes it possible to reliably recognize a printed pattern (character) on the upper side of key top even when the upper surface of the key top is slanted or curved, in which a key operating portion is given a rubber-like click sensitivity and a rubber-like elasticity, the key top portion is made from a rigid resin, and reliably strong bond is created between the key operating portion and the key top, and privides an illumination key that can reliably achieve ON/OFF operations while making it possible to reduce the weight of the key top without reducing the bonding strength between the keytop and the key operating portion. The illuminatioin key of the present invention comprises a partial transmission white-colored membrane or colored partial transmission type light reflecting membrane formed on an upper surface of the transparent resin key top excluding the underside surface of the key top; a pattern formed on an upper surface of the partial transmission type light reflecting membrane; an opaque layer covered the upper and side surfaces of the key top excluding the pattern formed portion; a transparent protection layer formed on the upper and side surfaces of the opaque layer; and an upper surface of the key operating portion made from a transparent rubber or thermoplastic elastomer being fixed to the underside surface of the key top by means of a transparent adhesive.</p> |
