Abstract
A crown switch actuator in a solid state analog wristwatch rotates in either direction and is movable axially. The actuator stem has a flat portion which rotatably operates a rocker contact spring against contact pads on a printed circuit board to alternately close first and second switches. The rocker contact spring also detents the switch actuator in one of two axial positions and retains the crown actuator in the watch case. Third and fourth switches are alternately closed by axial movement of the crown actuator stem. In a first detented axial position, the third switch is closed. In a second detected axial position, the third and fourth switches are open. In a third axial position, the fourth switch is closed. An extension arm on the detent rocker contact spring provides for releasing the crown actuator from the watch case.
