Abstract
A power activation device is provided which is controlled by an electrical signal so that the effective power activation signal wave form is made independent of the control input signal wave form through the use of a precise activation threshold so that the control input signal and the power activation signal are directly correlated through the same two input terminals. The precise activation threshold is determined by threshold elements such as a zener diode and the effective control signal which is supplied from the zener diode is independent of the input signal in both shape and duration.
