PROBLEM TO BE SOLVED: To provide a dial switch structure in which connecting switches are efficiently utilized using both side spaces of the printed-circuit board, and design freedom is expanded, and two operating knobs can be established, and reduction of components cost is possible. SOLUTION: A substrate 3 is provided in a switch main body constructed of a switch finisher 15b and a lower case 15a, dial knobs 21, 22 of nearly top-shape which is rotation operated are provided at the upper side part of the substrate 3 so that a part may be exposed from the side part on both sides of the switch main body, side part gears 23, 24 for axially rotating with the dial knobs 21, 22 are provided at the lower side part of the substrate 3, a rotation detection part for detecting the rotation is provided at the lower face of the substrate 3, and a center side gear 25 which is connected to the rotation detection part is provided at the lower part of the substrate 3 and engaged with the side part gears 23, 24 on the both sides.
