Abstract: A mechanical thermal battery initiator for a round where the initiator has a firing pin positioned to strike a primer of a thermal battery upon activation. After installation of the initiator/battery assembly in a round, the end user need not perform any further tasks until firing the munition. At launch, any safety device installed to prevent unintended activation is removed or switched to an active state. When launched, the initiator is subjected to centripetal force and acceleration causing a setback ring to release ball bearings and a spring force from a firing pin spring to push a firing pin into contact with a primer to initiate power on the round.
