A rotary cylinder which functions as a rotary shaft of a second rotary knob is fitted to the outer periphery of the fixed cylinder so as to drive slidable contact pieces for a second rotary switch. Spring coils for the first and second rotary knobs are mounted on the fixed cylinder. The spring coils provide the first and second rotary knobs with tensions for their rotation reference positions. Thus, the positions of slidable contact pieces of the rotary switches are elastically maintained to their reference angle positions.

  • Patent number: 5042017
    Abstract: An apparatus for generating a digital pulse train from a dial rotation indicating the direction and degree of rotation. The device incorporates two facing disks mounted to a stem and having mating teeth on adjacent surfaces. One disk is mounted for free rotation about the winding stem and projects an actuating lever arm from its periphery. The other disk is mounted for axial movement and is keyed to rotate with the shaft. Left and right micro-switches are mounted proximate the disks and positioned to be contacted by the actuating lever when it is rotated in the respective left and right directions. During this rotation the stem moves the keyed disk in the selected direction of rotation. The keyed disk engages the free disk and causes it to rotate until the actuating lever arm contacts a micro-switch. When such contact occurs, the free disk is prevented from further rotation and the keyed disk shifts over the teeth of the free disk.
