Two fixed contacts having substantially the same arc length at an angle of ° are provided, and three movable contacts are provided that are in sliding contact with the fixed contact, are equally spaced on the same circumference, and are electrically connected to each other. Since the structure includes a rotor having a rotor, there is no need to provide a notch in the fixed contact as in the conventional case, and the width of the fixed contact can be reduced, which in turn reduces the size of the fixed insulating plate and the rotary switch. It is possible to reduce the size of the contactor itself, and even if punched plates are used for the two types of fixed contacts, they can be of the same shape and are easy to manufacture.
