ABSTRACT:
A push-button switch capable of surely operating a switch element thereof and restoring an original position even when pressed at a corner thereof, while implementing a positive waterproof and dust-proof arrangement. A stub extends from the bottom of a push button and extends throughout an opening formed in a casing. The tip of the stub presses a switch element. A guide is fitted on the stub of the push button. When the push button is pressed at a corner thereof, the guide contacts the rear of the casing to form a fulcrum. As a result, the push button is caused to incline about the fulcrum.
