    An ignition system for a thermal battery where the ignition system includes: a base plate for connection to the thermal battery; and two or more inertial igniters formed on the base plate, each of the two or more inertial igniters having a striker mass which ignites one or more pyrotechnic materials upon a predetermined acceleration profile, the base plate having an opening corresponding to each of the two or more inertial igniters for allowing a generated spark to pass into the thermal battery.

  • Compact and Low-Volume Mechanical Igniter and Ignition Systems for Thermal Batteries and the Like

    A thermal battery including: a housing having a first compartment and a second compartment; a thermal battery housed in the first compartment; and an inertial igniter housed in the second compartment; where the first and second compartments are separated by a rigid member.
