Abstract: A timer assembly housing is configured to include a number of features, including but not limited to a tortuous sealing lip, adjustable hinge assembly, removable backing plate, removable pin hinge, toggle switch, and a wiring lid. The timer assembly includes a weatherproof housing having a base with a series of sidewalls and a rear wall, the base sidewalls extending forward from the rear wall to an open front, a lid having a series of sidewalls and a front wall, the lid sidewalls extending forward from the front wall, and a timer assembly positioned within the base. The lid is selectively pivotably secured to the base along one of the base sidewalls.

Abstract: The ignition safety device is mounted on a rocket motor nozzle having a body with a longitudinal nozzle opening having an igniter therein for igniting the propulsion charge of the rocket motor. An electrically operable detonator is mounted in a detonator opening in a housing mounted in the body. An actuator and a locking member are movable in the body between safe and armed positions. The locking member has means operative in its safe position for locking the actuator. Movement of the locking member to its armed position unlocks the actuator. A spring biases the locking member to its safe position. The actuator is adapted to operate a switch which initially short circuits the electrically operable detonator but is operable by the actuator to an armed position in which the detonator is no longer short circuited and is connected to an electrical input circuit including a contact band on the nozzle body.
