Abstract
Abstract An ordnance fuze having a detonation option selection circuit, an arm circuit and a detonation circuit. The detonation options are selected by option circuits responsive to a particular voltage magnitude and polarity to provide output signals which actuate a plurality of switches to select an energy path to the detonator. The paths may include timing circuits to allow detonation of the fuze after the occurrence of a sensed condition. The condition may be sensed by an impact switch or by a target detecting device. The arm circuit includes time delays, a delivery mode sensing device, safety devices and switches to arm the fuze at a time dependent on the delivery mode of the fuze.
