PROBLEM TO BE SOLVED: To provide a push switch with operation noise suppressed by a simple structure when a conductive disc spring is reversely bent. SOLUTION: In this push switch 1, a push button 6 is formed of a hard molded body 62 and an elastic body 61. A pressing projection part 9 and support parts 10 formed by the elastic body 61 abut on a top part of the disc spring 5 and on parts of its rim, respectively. When the projection part 9 is pressed down, the disc spring 5 is reversely bent. Its vibration is absorbed by the elastic body 61 abutting on the top part of the spring 5 and on the parts of its rim, thus suppressing operation noise due to the vibration. The disc spring 5 makes contact with selection contacts 4a, 4a in the course of reverse bending, thus mitigating shock produced when it hits against the lowest end and suppressing also operation noise due to collision.
