Abstract : The patent relates to an igniter mechanism for a rocket motor used for towing a load or extracting an air crew member from a disabled aircraft. The mechanism operates whenever a sufficient force is exerted on the tow line to shear a pin allowing closure of the switch. Electrical energy coupled to the switch is conducted to a squib which ignites a charge to cause ignition of the rocket motor propellant. The electrical switch mechanism can only be actuated by a predetermined pulling force on the tow line thereby causing the electrical contacts to be brought positively together.
