Abstract

An out-of-line igniter assembly having a primer located out-of-line of an nition train and movable to an in-line position for ignition of a main pyrotechnic charge. A housing has a raceway connected with a gas expansion chamber and a pellet chamber, and a slider having a primer and a striker assembly is movable in the raceway. Premature detonation of the primer causes the primer to fire into the gas expansion chamber but, in normal operation, the slider is moved so that the primer is fired into the pellet chamber. Movement of the slider causes the striker assembly to actuate when the slider is in an in-line position with the pellet chamber.
