When turning the cam by 90° resp. 120° degrees in clockwise direction, the plunger pin is moved through a curved opening in the body. After that, the plunger pin is protruded. Depending on the type, the plunger pin is moved back by a pressure spring in its original position (Type A), is held in protruded position (Type R), resp. is secured against accidental operation (Type S). In order to move the plunger pin, this safety version requires an additional pushing of the latch. see also... • List of Cam Action Indexing Plunger Types → Page 958 ff.
