ABSTRACT:
In a keytop in which a mark indicating a function of the corresponding key switch is printed on the top surface of a keytop body made of a synthetic resin, the mark being a letter, a character, a numeral, a word, a symbol, a sign, a figure, a pattern or the like, or any combination thereof, and the mark is coated with a resin coating, a transparent or semitransparent coating that is soft, not slippery, and lusterless, is applied on the whole surface of the keytop body including the resin coating. Such transparent or semitransparent coating gives a soft feeling to the tip of an operator's finger as well as the tip thereof is hard to slip off the keytop, and hence the feeling thereof on operation is comfortable and the operativity thereof is satisfactory. Moreover, a line of the contour of the resin coating becomes disappeared and it is possible to completely take off the luster thereof. Accordingly, a grade in the external appearance of the keytop can be improved.
