<P>PROBLEM TO BE SOLVED: To provide a key switch which allows a push operation with clear clicking feeling and without inclination of a key top to be performed with a relatively short stroke and in which uniform illumination of the key top can be achieved by considering arrangement of a control force transmission mechanism. <P>SOLUTION: A key switch includes: a key top 2; a base 3 which faces the key top 2 and in which a membrane switch 9 is disposed; a pair of link members 5a and 5b which transmits control force by the key top 2; and an elastic operation member 6 which transmits the control force by the key top 2 through the pair of link members 5a and 5b to control the membrane switch 9 on the base 3. The membrane switch 9 on the base 3, the pair of link members 5a and 5b and the elastic operation member 6 are arranged in a second space S2 opposite to a first space S1 on a face side of the base 3 facing the key top 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
