<p>PURPOSE:To miniaturize a switch by energizing electrically the fixed contact of a switch substrate, and the shaft of a rotary gear, by a movable contact provided at the rotary gear to reduce a train of fixed contact. CONSTITUTION:The rotary gear 45 of a mode detecting switch 43 which detects the angle of rotation of a subcam in a mode detecting system, is supported rotatably on the shaft 49 of the switch substrate 51, and the fixed contact 65 having six contacts 65a-65f, is arranged on the substrate 51. And a brush 63 as the movable contact is mounted on the rotary gear 45 so as to energize the fixed contact 65, and the shaft 49 electrically. When the subcam is rotated by operating a main rod, the gear 45 is rotated, and one of the fixed contacts, and the shaft 49 are energized, then, the angle of rotation of the subcam is detected. Therefore, it is possible to reduce a train of the fixed contact compared with a conventional detecting switch, and to miniaturize the switch.</p> |
