Abstract
A crash sensor for automobiles of the type including a ball moving against viscous damping in a closed cylinder for releasing a firing pin for initiating a pyrotechnic sequence has an improved release mechanism. When the ball moves a predetermined distance from its normal or resting position during an automobile crash it initiates a cascade of releases of increasingly larger and more powerful snap disks. The firing pin is mounted on and driven by the largest snap disk.
