Patent ID: 8536472

Claim:
A rotary switch mechanism, comprising: a main circuit board; a base disposed on said main circuit board; a first rotatable member disposed on said base and rotatable with respect to said base; a first signal-generating module mounted on said main circuit board, wherein in response to rotation of said first rotatable member, said first signal-generating module generates a first rotation signal; a second rotatable member disposed on said base, arranged around said first rotatable member, and rotatable with respect to said base; a second signal-generating module mounted on said main circuit board, wherein in response to rotation of said second rotatable member, said second signal-generating module generates a second rotation signal; and a push button disposed within said first rotatable member, and comprising a pushing surface, wherein said push button comprises: an optical finger navigation module disposed within said push button and arranged under said pushing surface of said push button for detecting a motion of a user's finger on said pushing surface, wherein in response to said motion of said user's finger, said optical finger navigation module generates a motion signal; and a push switch disposed under said optical finger navigation module, wherein when said push button is pressed down, said push switch is triggered to generate a triggering signal.
