Abstract
An electronic wristwatch includes an electronic circuit such as a lead frame with extending conductive strips providing a first battery contact terminal and switch contact terminal for operating and setting the wristwatch. A multipurpose switch actuator makes continuous electrical contact between the wristwatch battery and the first contact terminal, and makes selective switching contact with the second contact terminal when actuated by a push-pull detented stem. The stem is removable when twisted using a tool so as to unseat the detent spring, so that it can be pulled from the watch frame, and is also reinsertable without disassembling the watch. The switch actuator serves various other functions, including spring biasing of the stem detent and holding the electronic circuit lead frame in the watch frame.
