Abstract
A mechanical sensor, operable without any source of electrical energy, includes: a rolamite means, a support means for the rolamite means, a trigger means, a hammer means, a primer means and a biasing means. The rolamite means is responsive to acceleration or deceleration above a predetermined amount and is mounted on the support means. The support means provides a path of movement for a portion of the rolamite means during deceleration. The trigger means is located adjacent to the support means and has a first portion and a second portion. The first portion of the trigger means extends into the path of movement for a portion of the rolamite means. The hammer means is located adjacent to the trigger means and is releasable by the trigger means. The primer means is activated by the hammer. The biasing means biases the hammer means toward the primer means.
