PURPOSE:To make operation so simple enough by operating one or two touch switches at the same time according to a direction of rotation and a turning angle of a single operating shaft. CONSTITUTION:When an operating shaft 1 is rotated to an A direction from a neutral position, first of all, a first lever 6 comes into contact with a first touch switch 10 whereby this first touch switch 10 operates, and when the operating shaft 1 is further rotated in the A direction, a cam body 8 comes into contact with a third touch switch 12 which is thereby operated. Likewise, when the operating shaft 1 is rotated in a B direction from the neutral position, first a second switch 11 is operated by the same operation aforesaid, and when it is further rotated in the reverse direction, the third switch 12 also operates. Thus two stage operations are made performable by rotating only one operating shaft 1.
