ABSTRACT:
A single external stem member of an electronic timepiece operates independent switches by push-pull motions and by a rotary operation. Many functions are controlled or adjusted with signals generated by particular sequential combinations of stem member operations in the push-pull and rotary modes. In an alarm timepiece, the rotary switch controls the alarm time setting, and the push-pull switch determines whether an audible alarm and hour markers are to sound, no sounds are to be emitted, or only the alarm is to sound.
