Abstract
A water activated pressurized gas release device, especially suited for automatically controlling the release of the pressurized gas for inflating flotation equipment when dumped into water, which includes an electrically fireable primer for generating propulsion gas to drive a piercing pin into the closure of a container of pressurized gas to release the same, and fired by electrical energy derived from a battery arranged in a circuit maintained open on the ground side by electrically conductive elements providing two spaced apart electrodes until such space is filled with water for a predetermined duration of time as occurs upon immersion to close the circuit.
