An electrical circuit for electrically dischargeable primers having a
conductive body, a first electrical contact area, a bottom plate area, one
or more burn out area(s) on the bottom plate area, and a second electrical
contact area. The conductive body provides an electrical path between a
primer's inside cylindrical wall and an inside surface of the primer's cap
or cup. The first electrical contact area makes an electrical contact with
the inside surface of the cylindrical wall. The second electrical contact
area makes an electrical contact with an inside surface of the primer's
cap or cup. The bottom plate area is positioned in a bottom location of an
electrically dischargeable primer. At least one, but typically two or more
burn out areas are on the bottom plate area. The burn out areas have a
reduced cross section area. The total cross section area of the burn out
areas must be less than the cross section of any other location on the
elongated conductive body. Since the burn out area have a smaller cross
section area they will heat and burn faster than any other area when an
electrical current is applied. This assures the precise location of
ignition of primer powder.
