A time delay mechanism force fuze wherein the mechanism comprising an encoder ring, having an inner surface with a predetermined mask pattern of lands and grooves, is locked by a spring lock exerting pressure in a radially outward motion, thus enhanced when the fuze is exposed to the influence of dynamic forces from a gun, is shown. The spring lock cooperates with a lock pin such that a radially inward deflection of the lock pin deflects the spring lock so that the encoder ring with a reaction surface is unlocked and can be fully rotated by a setting collar acting through a detent spring on the reaction surface. If the encoder ring is locked, the detent spring is deflected over the reaction surface of the encoder ring when the setting collar is rotated, thereby preventing the encoder ring from being changed. A plurality of actuators, which determines a digital word that represents a length of time for a time delay in a digital timing circuit for the fuze, is actuated by the predetermined mask pattern. The digital word is changed by rotating the setting collar while the encoder ring is unlocked.
