PROBLEM TO BE SOLVED: To provide a push-button switch easy to perform the assembling works by decreasing the number of component parts. SOLUTION: A push-button switch is composed of a body 1 having an opening 11, an operation handle 2 to make seesaw motions when one end 21a exposed at the opening 11 or the other end 21b is turned, an electroconductive torsion coil spring 3 furnished with a coil part 31 and having such a structure that two arms 32a and 32b installed extensionally to the sides of the coil part 31 are put in resilient contact with the body 1 with seesaw motions of the handle 2, a common terminal 4 fixed to the body 1 and connected electrically with the coil part 31, and stationary terminals 51 and 52 fixed to the body 1 and having stationary contacts 51a and 52a, wherein the torsion coil spring 3 is structured so that the arms 32a and 32b contact with and separate from the stationary contacts 51a and 52a with the seesaw motions of the handle 2.
