Abstract
A shock sensor has a mercury-wetted insert for supporting a mercury mass normally space from a terminal. The mercury and terminal are contained within a sealed housing. When the sensor is subjected to a shock, the mercury is redistributed and protrudes from the insert so as to contact the terminal and complete a circuit between that terminal and another terminal that is normally in communication with the mercury.
