A switch comprises a key top to be pushed down; an operation knob pushed down by the key top to rotate around a pivot point, having a working portion; and a contact rubber switch pushed down by the working portion of the operation knob. The rubber switch is provided with a push-button portion having an upper surface pushed down by the working portion of the operation knob and an under surface formed with a movable contact; and a skirt portion extending obliquely downward from an edge of the push-button portion. The skirt portion has a thinner portion on the side of the pivot point of the operation knob and a thicker portion on the opposite side of the pivot point. The push-button portion has an upper surface inclined upward toward the side of the pivot point. The switch has advantages such as simple structure, reliable conduction, and excellent click feeling.
