Abstract
A swimmer distress signal of the smoke or flare type has an ignition system hich can be operated with one hand. A stab primer is activated by a sliding firing pin that is normally locked in position and protected by a metal cover. Upon withdrawal of the signal from a pouch, a lanyard pulls off the cover to expose and unlock the firing pin which has an enlarged head. A hit or force on the firing pin head drives it into the primer to ignite the display.
