A connector and a connector device that are small and have a drainage function are provided. A connector includes: a contact; a first insulator; a first shield member; a second shield member having a tubular portion; and a second insulator. A first communicating portion that is in communication with the outside is formed in a lower wall of the tubular portion of the second shield member, the lower wall facing the second insulator. A second communicating portion that is in communication with the outside and the first communicating portion is formed in the second insulator. The first shield member has a facing wall that faces the first communicating portion, and a bent wall that is bent toward the second insulator from an end portion of the facing wall on an opposite side to the opening side.

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.

Keytop

In a pantograph type keyboard switch, a leaf spring projects from a linkage member and slidably engages the underside of a keytop and the resulting reaction force is used to remove play between the keytop and the linkage member. Further, a frictional slope is formed in each slide groove in the underside of the keytop so that frictional force increases as the keytop approaches the top dead point position.
