PURPOSE: To obtain various kinds of keyboards having satisfactory key touch and excellent operability by providing a coil spring and a rubber elastic body on an operating part for transmitting the depressing operation of a pushbutton to a switch part.

CONSTITUTION: An operating part 23 is formed of a pushbutton 24, a slider 25 on which the pushbutton 24 is fitted, an inner slider 27 held by the center part of the slider in such a manner as to be capable of sliding, a compression coil spring 26 supported between the slider 25 and the inner slider 27, a doom- shaped rubber elastic body 28 situated on the lower side of the inner slider 27 and pushed by the inner slider 27 to transmit the pushing operation to a switch part, and a housing 29 mounted to the switch part with holding the slider 25 in such a manner as to be capable of sliding and receiving the rubber elastic body 28 therein. As the coil spring and the rubber elastic body are thus integrated in series into the operating part, a satisfactory key touch having a larger stroke by the coil spring and a snap action by the rubber elastic body can be achieved.
