摘要：
Acceleration sensing apparatus comprises a casing having a pair of substantially perpendicular passages communicating with each other and accommodating spaced apart, normally open electrical contacts. One of the passages contains mercury which is operable to flow into the other passage in response to predetermined acceleration of the casing and bridge the conductors so as to establish a current path therebetween.
