A push switch includes an upper movable contact, a lower movable contact, a center fixed contact, an intermediate fixed contact, and a peripheral fixed contact. The lower movable contact includes an annular portion, and four legs extending from the annular portion. One of the four legs is placed on a peripheral fixed contact. The upper movable contact faces the center fixed contact through a circular hole in the annular portion of the lower movable contact via a space between the upper movable contact and the center fixed contact. Two legs out of the four legs are located away from each other by an angular interval smaller than 90 degrees with respect to the center of the annular portion. Upon being pressed, the actuator activates two combinations of switch contacts, one combination including the movable contacts and the intermediate fixed contact and the other combination including the movable contacts and the center fixed contact, providing the push switch with a small size.
