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.

Abstract: A control system is provided for igniting and dispensing a smoke pot for ense of a hulled vehicle. The system utilizes a command circuit located inside the vehicle for using the vehicles power source to select smoke pot operations. A user can select an operation to ignite a desired smoke pot or an operation to ignite and release the smoke pot. Two power lines are arranged from the command circuit inside the vehicle to a control circuit located at the exterior of the hull for operating the smoke pot control system. A minimum number of apertures are required in leading the power lines to the control circuit. The control circuit activates the selected operations of the smoke pots.
