A different kind of Geneva Wheel, or Maltese Cross. In this one, the input wheel (blue) has the grooves and the output cross (yellow) has the pins. It uses an actuator (red) pushed by a torsion spring to force the output pins inside the input grooves. The actuator is assembled on the top of the output, and it has a groove to work as a limit. The output wheel has a pin which slides inside that groove. This mechanism only works in one direction.
