Abstract
An electrical system for launching separate salvos, comprised of squibs, jectile bombs or the like, at different times but at the same launch location from a remote position using a single electrical control wire for carrying the current. The system is comprised of a negative polarity relay and a positive polarity relay respectively connected with a first and second salvo, a power supply comprised of two 24 volt batteries supplying power to the circuit from opposite terminals, a selecting switch connected with the batteries to select either positive or negative current to match the relay and salvo desired to be fired, an ignition switch for closing the circuit and a single control wire running from the ignition switch to the relays carrying the positive or negative current required for launching the chosen salvo. By using the selector switch and matching the polarity sensitive relay of the salvo to be fired with the enabling current and pressing the ignition switch, only the desired relay contacts close and the projectiles are launched.
