Abstract:
An electrical circuit for an electrically dischargeable primer comprising said first and second electrical contacts extending upwardly from the bottom plate area:a conductive body made from an electrically conductive material for providing an electrical path between an inside surface of an electrically dischargeable primer's cylindrical wall and an inside bottom surface of a an electrically dischargeable primer's cup or cap, said conductive body being the only electrical path between said cylindrical wall and said cap or cup; a first electrical contact area being a first end of said conductive body, said first electrical contact area for making an electrical contact with an inside surface of a cylindrical wall of said electrically dischargeable primer; a bottom plate area between said first end and a second end of said conductive body, said bottom plate area for placement within a bottom location within said electrically dischargeable primer; one or more burn out area or areas on said bottom plate area, each of said burn out areas having a reduced cross sectional area with a total cross section area of all of said burn out areas less than any other cross sectional area of said conductive body and said bottom plate area; and a second electrical contact area extending from said bottom plate area, said second electrical contact area providing an electrical path for said electric circuit to a cap or cup of said electrically dischargeable primers; said first and second electrical contacts extending upwardly from the bottom plate area.
