Pressure Activated Switches
As an underwater vehicle transits from the surface to the seafloor, then back again, it can be useful to have a simple switch to turn things on or off. This small pressure activated switch is built around a super strong, corrosion proof Ti 6-4 body and a high reliability mechanical switch rated for over 100,000 actuations. The switch works with either a sphere or a flat endcap, turning a circuit on or off between 2-3 atmospheres depth differential, then tolerating the high over-pressure of any ocean trench. We built them to turn on our recovery Beacon Board as a benthic lander approaches the surface, while other designers saw them as a safety switch for underwater lasers, arming circuits, or other functions.
