A time delay fuze is shown to include a fuze base having an outer surface with a circular shape and a center cavity with an inner wall having a plurality of bores disposed through the inner wall to the outer surface. The time delay fuze further includes a plurality of encoder rings disposed about the fuze base, each one of the encoder rings having an inner surface with a predetermined arrangement of lands and grooves, the inner surface of each one of the encoder rings disposed adjacent the outer surface of the fuze base and a circuit board having a plurality of switches disposed in the center cavity of the fuze base. Completing the time delay fuze are a plurality of actuating pins disposed in corresponding bores provided in the inner wall of the center cavity, each one of the actuating pins having a first and a second end with the first end adjacent and interacting with the land and grooves of the inner surface of one of the encoder rings and the second end adjacent and actuating a corresponding one of the plurality of switches. With such an arrangement, the encoder rings are easily rotated, in turn, activating the plurality of switches to set the time delay of the fuze.
