Dual function pusher and rotate switch for solid state digital watches having detent spring

A dual function rotate and pusher stem device and switch assembly for a digital watch having a case with an opening for access to the interior thereof which comprises:

• a shaft mountable in said opening for axial and rotational movement and having an eccentric tab at the interior end thereof, and an intermediate section having a detent retainer section, and an end portion projecting outwardly from the case;
• a first switch blade mounted for selective engagement with the eccentric tab with the shaft being in a first detent position and pushed-in longitudinally;
• a second switch blade mounted for selective engagement with the eccentric tab with the shaft being rotated to a second detent position;
• biasing means engaging the detent retainer section to provide a detent action and for engaging the shaft to urge the shaft into a longitudinal position to disengage the eccentric tab from the first switch blade, said shaft being pushed-in longitudinally against the bias of the biasing means to a longitudinal position to engage the eccentric tab with the first switch blade, said biasing means returning said shaft to the disengaged longitudinal position upon release of the shaft.
