ABSTRACT:
A fuze setting device utilizes a plurality of detented, rotatable, magnet sitioning time setting rings and an encoding disc for controlling the amount of electrical pulses that a timing oscillator is required to subsequently generate to fill an "and" gate controlled multi-stage counter. The counter after being filled generates a fuze initiating signal. A setback detented electromagnetic pulse generating despin operated sensor assembly is used in combination with the oscillator to generate electrical pulses for partially filling the counters in accordance with the relative angular positioning between the magnetic source setting rings and the pole pieces of electrical coils which generate a stop pulse to regulate the number of pulses necessary to fill the counters.
