can be increased for a given device activation spin rate as a result the potential energy stored in the spring 105 increased thereby increasing the kinetic energy of the striker link 101 as the pyrotechnic components 106 and 114 impact this capability of the inertial igniter embodiment 100 and g switch embodiment 150 is particularly important in applications in which the spin rate of the munitions using these devices is relatively low another embodiment 300 of the present inertia igniter invention is shown in the schematic of fig9 a in this embodiment the striker component of the inertial igniter 300 is the striker link 301 which is attached to the structure of the inertial igniter 302 by a pin joint indicated with numeral 303 a spring 305 which can be preloaded in tension is attached to the structure of the inertial igniter 302 on the end 306 and to the striker link 301 on the other end 307 preferably with pin or pin like joints in its pre activation state shown in fig9 a the striker link 301 is pressed such as near its tip 308 against a rotating link 309 through an intermediate ball 310 the link 309 is attached to the structure of the inertial igniter 302 via a rotary joint 311 which allows it to rotate about the axis 312 the axis 312 is parallel to the plane of view of fig9 a thereby allowing the link 309 to rotate up or down relative to the plane of the rotation of striker link 301 a mass 317 is attached to the.
