A switch which can widen a degree of freedom of setting height and shape of a click groove while providing a click groove on a side of a movable contact and promote operation feeling without increasing cost. This switch brings a movable contact into contact with a fixed contact and separates the movable contact therefrom by pivoting a movable piece by moving a steel ball on the movable piece by operating a switch knob; wherein the movable piece is provided with a flat click portion having a contact portion and a click groove at an end edge thereof, the click portion being arranged erect relative to a housing; a steel ball contained in a ball support portion via a coil spring; and an opening of the ball support portion provided with a fitting groove to be fitted loosely to the end edge of the click portion of the movable piece.
