Thermally actuated latch releases component initially secured to it, when cooled to predetermined temperature lower than initial temperature. Includes supporting arm and spring-loaded hook made of titanium, and engaging arm made of epoxy or high-density polyethylene. As latch cools, engaging arm shrinks away from hook, and spring drives hook away from arm. Latch used to retain cover of cryogenic aerospace instrument during launch through intermediate cooling. With nonmoving hook, latch used to prevent door of industrial furnace from being opened until furnace cools to safe temperature.
