ABSTRACT:
A multiple payload cartridge employing circuit components in the squib portion thereof to allow for separate or sequential firing thereof, and hence separate payload ejection, through two-wire connections. Various techniques include the use of a repositionable switch to provide sequential ground connections; the use of mechanical interrupters, e.g., spring-type, crushable-element-type or domed-pop-action type; the use of resistive voltage dividers to permit discrimination in squib firing via applied voltage amplitudes; the use of diodes to permit discrimination in squib firing via applied voltage polarities; and combinations of the above.
