Abstract
A rotational operation type switch includes a frame; a rotational operation button rotatably supported on the frame for rotational operation; a switching contact mechanism disposed below the operation button to face the operation button; and an operation mechanism disposed between the operation button and the switching contact mechanism, to switch the switching contact mechanism in conjunction with the rotational operation of the operation button. The switching contact mechanism includes a printed circuit board, a plurality of fixed contact electrodes disposed on the printed circuit board and spaced a predetermined distance away from each other, and a movable contact having a disc spring shape and disposed bridging between the plurality of fixed contact electrodes. The movable contact deforms to contact and separate from the fixed contact electrodes and switches an electrical connection between the fixed contact electrodes.
