<p>A water activated pressurized gas release device utilized for inflating flotation equipment, such as life jackets, when dumped into the water includes a one piece die cast housing (12) formed of an electrically conductive material, all major components of the device, with the exception of the container of pressurized gas (14) and a manual actuating device (18) being mounted within the housing. A portion of the housing or container acts as a first contact when immersed in an electrically conductive fluid. A battery (64) is disposed within an insulating sleeve (76) within a battery bore (34) in the housing (12), the battery in turn being enclosed by an apertured closure (84) which exposes the anode (74) of the battery whereby the anode may act as a second contact. Electrical circuit means (62) are disposed within a cavity (36) in line with the battery, the electrical circuit means being enclosed by a potting compound (80) which also serves to maintain a cover 82 in place over the cavity. The gas passageway between a transverse D-shaped hole (30) and a longitudinally extending piercing pin receiving bore (24) is formed by a keyway (32) parallel to the D-shaped hole and which intersects the D-shaped hole and the piercing pin receiving bore thereby reducing machining costs. <IMAGE></p> |
