ABSTRACT:
In a switch mechanism for an electronic timepiece, stationary switch electrodes are fitted in openings provided in a dielectric base plate. Movable contacts on a pivoted switch lever extend into the openings and are normally out of contact with the electrodes. The switch lever is movable by operation of the watch stem to bring one or another of the movable contacts into engagement with the respective electrode and thereby close the circuit, for example for adjusting the hour and minute displays of the timepiece. This construction permits making the timepiece thin.
