Abstract
An improved selective switch includes a printed circuit board, a rotating shaft with a pinion, two bearings journalling the rotating shaft on the printed circuit board, a sliding member slidably mounted on the printed circuit board and a rack meshed with the pinion, thereby, when the rotating shaft is rotated, by the linking-up motion of the rack and the pinion, the sliding member will be driven to slide on the printed circuit board so that the selective control of the selective switch is achieved.
