DESCRIPTION: The A.Z. 2  fuze consists of a steel striker and a detonator pellet which are kept apart by centrifugal segments which are kept closed by a split spring. There is a detent in the fuze which prevents the opening segment from opening until after firing, i. e., the detent sets back on firing thereby permitting the segments to swing out through centrifugal force during deceleration. (See fig. 588.)

The setting plug can be so set to include nondelay or delay action pending the amount of travel the disk is allowed to move out by centrifugal force opening the central flash hole to the side containing the delay element.

OPERATION: After the projectile is fired, the detent locking the centrifugal segments sets back, the spring surrounding the segments expands, and the segments swing out one by one due to centrifugal force. This leaves the striker resting on the creep spring. Upon impact the striker moves forward to fire the detonator, the flash from which, pas-ses through either the central flash channel or the delay channel depending on the posi-tion of the setting plug.
