  • Patent number: 3934401
    Abstract: A multi-position switch particularly adaptable for an electronic watch comprises a movable plate or disk mounted within a cup-like body and rotatable about an axis to different positions for accomplishing various setting or operating modes. Fixed contacts on the inside of the switch plate are spaced apart but electrically connected so that when the plate is rotated to certain positions relative to its central axis the contacts are aligned for engagement with a particular pair of a series of terminals located on the inside planar surface of the switch body and connected through the body to the internal circuitry of the device. The interconnection of certain pairs of terminals accomplished by the contacts activates internal circuitry of the device to produce the desired operating function or mode.
