A rotary switch (1), which is used to detect a state of a stand with respect to a body of a motorcycle, for example, comprises a housing (2) having a ring-shaped outer wall (21 a) so that an annular recess (20) is formed; a rotor (3) which is rotatably supported on the housing (2) around a center axis of the annular recess (20); a plurality of stationary contacts (41A, 41B) each having a circulararc shape and provided on a bottom face of the annular recess (20); a moving contact (42) which is provided on the rotor (3, 33) and is connected and disconnected with the stationary contacts (41A, 41B) following to rotation of the rotor (3) with respect to the housing (2); and a cable draw-out portion (22) from which an electric cable (70) including a plurality of inner cables (71) respectively connected to at least the stationary terminals (41A, 41B) is drawn out from the housing. The rotor (3) has a U-shaped joint (32) which holds an end portion of the stand pivotally mounted on the body, so that the rotor (3) rotates corresponding to rotation of the stand with respect to the stationary portion.
