Abstract

A keyboard switch having a keytop which is displaced vertically by a cross link that comprises a first link member and a second link. A front edge side of the keytop comes slightly lower than its rear edge side and the cross link is configured so that the pushdown stroke is greater on the rear edge side than on the front edge side and that the top face of the keytop. When the keytop is pushed down completely, it comes almost parallel to a frame of the keyboard switch. This configuration, when adopted, for example, to a notebook type personal computer with a lid, results in sliding an elastic portion which holds up the keytop in interlock with the lid closing, thus the keytop, as a whole horizontal. This configuration wherefore allows achieving otherwise contradictory effects of a great stroke when the lid is opened and a thinner notebook when the lid is closed. Further, the top surface of the keytop when it becomes nearly parallel, facilitates character printing improving the printing yield.
