Switching circuit ensuring safety in weapon system - has flip=flop circuit preventing firing on actuating switches in wrong order

摘要

The switching circuit is used for ensuring safety in electrically actuated weapons system. The system can fire only if it is set to state ready to fire and the firing switch is actuated. Reverse order of actuation ensures automatically safe state. Firing and subsequent return to safety is independent of the duration of switch actuation by hand. The circuit has a first flip-flop with basic state erase and second state for set. The erase state corresponds to safe state and set state to the ready to fire state. Output of flip-flop is connected to AND element. The latter is connected to push-button for firing and to system generating firing pulse. The flip-flop has at least four erasing inputs.
