Abstract: Electroexplosive device and static discharge element therefor. The electroexplosive device herein has a cylindrical metallic casing which is open at one end and closed at the other end, a bridge element and lead wires therefor, a static discharge disc surrounding the lead wires for preventing accidental ignition due to static electricity, and a ferrite sleeve surrounding the lead wires to prevent accidental initiation due to radio frequency currents. The static discharge element comprises a nonconductive circular substrate having a slotted opening for the lead wires, and a conductive coating layer on at least one face of the substrate to conduct electricity from the leads to the casing in the event of electrostatic discharge. This conductive layer should be in electrical contact with the casing but not with the lead wires; to that end the substrate is left uncoated in the immediate vicinity of the opening.
