ABSTRACT:
An inertial mass is forced from an initial position against a compression spring by sustained acceleration of a predetermined value to travel to the end of a zig-zag channel where it is locked into place in engagement with four contacts and thereby enables an electric circuit for the firing of a squib by a firing command signal. When the firing command is given, the squib fires and the resulting pressure forces a piston to break a shear pin and move whereby the hot gases are forced into a flame tube hole previously blocked by the piston. The hole may be packed with ignition granules which speed propogation of the flame to an igniter. In the event the squib is fired inadvertently with the inertial mass in the initial position thereof, the piston is restrained by the inertial mass and cannot move to unblock the flame tube hole. As a result, the hot gases are retained harmlessly in the space provided.
