Electronic circuit for correction of the time display on an electronic timepiece
摘要:
An electronic circuit for correction of the time display on an electronic timepiece, this circuit including a selector switch having a rest position for which the timepiece advances normally, and operating positions for minute setting, hour setting and day setting. Delay means are connected between said selector switch and the setting means of one or more display means for minutes, hours or days in order that such setting means only start to operate when the selector switch has been shifted to the operating position for a sufficiently long time, but are inoperative if the selector switch is rapidly shifted through this operating position.
