Switching mechanism in an electronic watch

摘要

A switching mechanism in an electronic watch including a clicking mechanism comprising a clicking cam which is mounted for rotation on an operative rod and a spring which is fixed to a base plate. The clicking cam is provided with a peripheral projecting portion. The spring is provided with a convex portion. In a switching operation, the projecting portion of the cam engages with the convex portion of the spring during the rotation of the cam which is rotated together with the operative rod. After passing through a dead point where the cam disengages with the spring, the cam continues to rotate due to the restoring force of the spring. Then, a click sound is produced at the engagement and the disengagement therebetween.
