ABSTRACT:
A nonpredictable, nondeterministic actuator for switches or the like having two unsynchronized pulse generators delivering pulses to an AND gate which passes an actuating signal only when the pulses from the generators are coincidental. One generator produces a pulse train at a frequency much higher than the other generator which produces very short pulses and has a maximum timing uncertainty or jitter which is greater than the period of the first mentioned generator.
