ABSTRACT:
A safety, locking, pull ring for a munition which must be deformed and simultaneously rotated from a protecting locking recess and which must then be rotated 180 degrees from the recessed position in order to free one end of a pivotably attached bar. The bar must then be rotated 180 degrees, using the ring as a handle, to expose both a safety wire which must be removed to arm the munition, and expose an indicator light, which indicates the safe or unsafe condition of the munition, and finally to crush an ampule to release electrolyte to energize a battery which powers the munition electronic circuitry.
