The Spring Trigger. A spring trigger is actually a small spring with a threaded end that replaces the hard trigger on specially made index-triggered releases. Because it bends when you pull it, the spring is very difficult to punch. Your only recourse is to keep pulling as you continue to aim at the spot you want to hit.
Schmitt trigger. Â© A Dictionary of Computing 2004, originally published by Oxford University Press 2004. Schmitt trigger A discrete or integrated circuit whose output has two stable states, i.e. two sustainable values of output voltage, to which it is driven by the movement of its input voltage past two well-defined trigger values. A rise in input voltage above one trigger level causes the output to switch to one state. A fall in input voltage below the other trigger level causes the output to switch to the other state. The difference between the positive and negative thresholds is known as the circuits hysteresis. For the output to change, the input must exceed the hysteresis and be of the appropriate polarity.
