In a rotary switch in which a switching spring is locked to a lever and a switching cam, a through hole through which the cam support shaft is inserted is formed at one end of the switching cam, and the through hole communicates with the switching cam. A slit is formed along the through hole at the end of the end, and a shaft engagement protrusion is integrally formed on the inner peripheral surface of the end of the through hole opposite to the insulating base along the circumferential direction. A rotary switch characterized in that a ring-shaped groove into which a shaft engagement protrusion is fitted is formed at an end of the cam support shaft.
