ABSTRACT:
A multiple payload cartridge connectible to a source of firing signals by two connecting wires having a first and a second branch each having a squib therein connected in parallel across the connecting wires is characterized by a zener diode connected in series with the second squib in the branch containing the same. The zener diode prevents the flow of current through the branch with the second squib until a firing signal of a predetermined polarity and a magnitude greater than the breakdown voltage of the zener diode is applied across the second branch. The zener diode responds to that firing signal by breaking down into a low resistance conduction path to thereby permit an electrical current sufficient to raise the second squib to incandescence to flow therethrough.
