Abstract: An air-flow actuated power supply and switch device having a pop-up cover which includes an air scoop, a switch actuator mechanism and an interface cable as a part thereof. The power supply is activated by pulling a lanyard which causes the pop-up cover to rise and expose an air scoop causing electrical energy to be generated for operating an electric bomb fuze or the like. A breakaway coaxial cable incorporated in the device permits the injection of electrical signals from the aircraft to the fuze system by a radiation hazard detection system.
