<P>PROBLEM TO BE SOLVED: To provide a push-button switch device for an elevator which can inexpensively be manufactured by properly attaining an input to a switch element, even if an operation body is slantingly operated, by only using a single switch element. Ž<P>SOLUTION: The operation body 15 composed of a button top 16 and a holder 17 is elastically energized by coil springs 20 and 29, and pushed in against its energizing force. An operational projection 22 is integrally formed at the holder 17, and a push-switch 25 is oppositely arranged to the operational projection 22. The push-switch 25 has an operation piece 27, and the operation piece 27 is pressed by a tip surface 22a of the operational projection 22 according to the push-in of the operation body 15. The tip surface 22a of the operational projection 22 becomes a curved surface of projecting in a hemispherical shape, and thus, even if the operational projection 22 contacts with the operation piece 27 by inclining in the axial direction of the push-switch 25, the operation piece 27 moves in the axial direction regardless of its inclination.
