Electrostatic Safe Electric Match.
Abstract
A safe electroexplosive device such as an electric match is provided by covering the existing electric match with a coating that prevents electrostatic discharge penetration of the coatings. The coating may be either an inner insulator with a conductive outer layer or it may be just a conductive layer over the match. Use of the insulator coating allows an open-circuit terminal to remain once the device is initiated by its power source. Use of only the conductive coat requires the coat to have a resistance greater than the match bridgewire circuit resistance and leaves a low resistance path across the power source after the device has been fired.
