PROBLEM TO BE SOLVED: To provide a rotary switch mechanism capable of preventing the occurrence of contact failure caused by a pair of contacts in an electronic circuit being rubbed with each other.SOLUTION: A rotary switch mechanism includes a first circuit substrate 37 having a first conductive part 43, a second circuit substrate 38 having a second conductive part 45, and a coil spring 34 provided in a rotation operation unit 32 and drawing a rotational trajectory T. The second circuit substrate 38 is provided on a support part 31 with the second conductive part 45 on the rotational trajectory T; and the first circuit substrate 37 is provided with the first conductive part 43 being opposite to the second conductive part 45. The coil spring 34 has a pressure axial direction coinciding with a direction where the first conductive part 43 and the second conductive part 45 are opposite to each other; and when the rotation operation unit 32 is brought into a predetermined rotational attitude, a conductive back portion 49 being a back face of the second conductive part 45 is pressed on the back of the second circuit substrate 38, so as to press the second conductive part 45 against the first conductive part 43. |
