ABSTRACT:
The precision ignition device disclosed in U.S. Pat. No. 4,708,060 is combined with the device disclosed in U.S. Pat. No. 5,036,768, and U.S. Ser. No. 07/584,045 to provide accurate control over the ignition of an EED while also protecting that EED from inadvertent firing caused by exposure to extraneous electricity, such as RF energy or electrostatic energy. The combined device can be connected to a source of power and/or to an external sequential timer for further control over the firing process. A method of fabricating the means for protecting the EED from inadvertent extraneous electricity induced firing is also disclosed.
