ABSTRACT:
A pushbutton switch for use in a keyboard incorporated in an electronic typewriter, work processor, or the like gives a tactile feel to the finger of the operator corresponding to a clicking operation and, at the same time, produces a clicking sound. The switch comprises a casing, a switching device in the casing, a stem, and a leaf spring. This spring has an upright portion and a bent portion. The leaf spring is so mounted in the casing that when the stem is depressed, the bent portion is reciprocated. This causes the upright portion to collide with the inner surface of one side wall of the casing, thus producing a clicking sound.
