The driven cam portion 1901 is an end surface cam formed in a circumferential shape, and inclined surfaces inclined at four places are formed at intervals of 90 degrees in the circumferential direction. The inclination of the driven cam portion 1901 of the cam member 190 substantially matches the inclination of the driving cam portion 133 of the switch lever 13 , and the driving cam portion 133 of the switch lever 13 is engaged with the driven cam portion 1901 of the cam member 190 . When the driving cam part 133 is engaged with the driven cam part 1901, the driven cam part 1901 of the cam member 190 slides on the inclined surface of the driving cam part 133, and the rocking action based on the operation accepted by the switching lever 13 is automatically moved. The cam portion 133 is transmitted to the cam member 190 via the driven cam portion 1901, and the cam member 190 operates in the vertical direction. Two engaging protrusions 1902 are protruded at a 180-degree interval on the side surface of the lower stage side of the cam member 190 . The engaging protrusion 1902 protruding from the cam member 190 is engaged with a guide groove (not shown) recessed in the vertical direction on the inner wall of the through hole 104 of the fixing member 10 . As the engaging protrusion 1902 is engaged with the guide groove, the movement of the cam member 190 is guided by the guide groove and adjusted in the up-down direction.

In addition, the names of the hitting objects are described as the rigid part 103 and the elastic part 1900, but these names are relative meanings of each part, and those that are likely to generate sound due to vibration during hitting are called rigid parts. 103. The elastic portion 1900 is referred to as the elastic portion 1900 that absorbs the impact of the blow and makes it difficult to generate sound. Therefore, the rigid part 103 and the elastic part 1900 do not absolutely limit the material, structure, shape, characteristics, etc. of these parts.

That is, the arrangement position of the sliding rigid portion 1E1 of the struck member 1E is within the movement range of the striking member 16 . When the contacting and disengaging state is switched by the pressing operation on the movable member 11 , the striking member 16 is biased by the second biasing member 17 and is strongly moved downward. Since the sliding rigid portion 1E1 is arranged within the movement range of the striking member 16, the striking member 16 strikes the sliding rigid portion 1E1 from above. The sliding rigid portion 1E1 is hit by the hitting member 16, so that a sound is generated during hitting.

As described above, in the key switch 1 of the third embodiment, when the arrangement position of the sliding rigid portion 1E1 of the struck member 1E deviates from the movement range of the striking member 16, the striking member 16 does not strike object, thus suppressing the generation of sound caused by hitting. When the arrangement position of the sliding rigid portion 1E1 of the struck member 1E is within the moving range of the striking member 16 by the switching operation, the striking member 16 strikes the sliding rigid portion 1E1 of the struck member 1E, so that Produces a sound when struck.
