ABSTRACT:
Disclosed is a safe/arm detonator assembly for use with an oil well perforating gun assembly having two housing members sealingly isolated from well bore fluid and which are rotatable from a safe position wherein a detonator and a booster are held out of alignment, to an armed position wherein the detonator and booster are moved into alignment. The detonator assembly is further arranged to be installed in a well perforating gun assembly such that the gun assembly may be transported with the detonator assembly in the safe position, and rotated to the armed position at the well site without disassembling the gun assembly. A safety pin is further disclosed which may be included in one of the housing members to cover and protect the booster from accidental detonation when the detonator assembly is in the safe position.
