Automatic lifejacket reflectable cartridge/capsule (often called a "bobbin" or "salt pill") is a critical component in self-inflating personal flotation devices (PFDs) designed to automatically trigger inflation within 3–5 seconds of immersion in water. The cartridge contains a water-soluble tablet that dissolves upon contact with water, releasing a high-powered spring that causes a needle to puncture a CO2 cylinder, instantly inflating the bladder to ensure the user stays afloat.
