Title: Switching device for electronic timepiece

Abstract: A switching mechanism for an electronic timepiece is disclosed. The switching mechanism comprises an external means for selectively activating an internal switching assembly. The external means is rotatably coupled to a grooved rod member which is in turn coupled to the internal assembly. Various contact arms disposed across the grooved rod member are adapted to become selectively disposed on various electrical contacts in the timepiece. By rotating the grooved rod member, these arms are selectively disposed on or off corresponding electrical contacts thus causing the internal switch assembly to be turned ON or OFF. By the use of the invented switching mechanism, various internal switching assemblies such as for alarm systems and the like may be easily activated and deactivated without the problems associated with prior art switching mechanisms.
