Input: blue face gear (tooth-uncompleted) rotating continuously.
Output: green gear (tooth-uncompleted) that performs interrupted rotation. In 1 input revolution it turns 360 deg. (with the support of the flat spring) and dwells (thanks to flat (no teeth) section of the blue face gear).
The original green gear (tooth-completed) has 10 teeth.
Increase the blue gear diameter for a larger dwell/motion time ratio of the output.
