Abstract (en)
The invention comprises a trigger mechanism for use in marine applications for example to control the release of liferafts from ships, or for controlling the inflation of liferafts and life jackets. The mechanism is two stage in operation in that a first sense and respond device must be operated before a second sense and respond device is operated, and the second sense and response device is of the moisture or water presence controlled type. The first sense and response device is of such a nature to prevent water from reaching the second sense and response device until the first device is triggered. Specifically, the first device includes a membrane which is ruptured when subjected to water pressure so that the water can flow through the ruptured membrane and actuate the second device. Thus, if the mechanism is part of something which falls or is thrown into the sea, the pressure of the sea water deflects and causes rupture of the membrane and the sea water flows through the membrane and actuates the second device and the liferaft is released or the jacket or raft is inflated automatically as the case may be. <IMAGE>
