Disclosed is a key switch comprising a key top for receiving pressure from a user's finger, a link for lowering the key top when pressure is applied to the key top and pushing the key top upwardly when the pressure is released, and a flexible printed circuit (FPC) provided on an upper surface of a keyboard frame for recognizing the key action by a pressing-contact of the link therewith. The link has first and second legs pivot-coupled with each other, a return plate spring applying a returning force to the key top, and a contact plate spring coming into pressing-contact with the FPC. The key switch has a simple structure and imparts a sufficient clicking sensation.
