<p>A key switch wherein a key top (1) made of thermoplastic resin and a extruding part (2) made of thermoplastic elastomer are integrally formed, thereby improving clicking touch of a contact member, such as a metal belleville spring, a resin film dome or the like, which is placed underneath the extruding part and preventing breakage and laceration of the contact member. Further, a key switch is constructed such that extruding parts (2) of a plurality of key tops (1) are integrally linked by means of a U-shaped bridging member (3) made of thermoplastic elastomer, thereby causing elastic deformation of the bridging member (3) at the time of pressing one of the plurality of key tops (1) so that an extruding part (2) of an adjacent key top is prevented from operating together. <IMAGE></p> |
