Flat electric match

Abstract

A flat electric match includes a substrate having a surface. A first electrical lead and a second electrical lead each having an end, are carried by the substrate on the surface. The ends of the electrical leads are spaced apart on the surface. A bridge wire is coupled between the ends of the electrical leads and carried by the substrate on the surface. A pyrotechnic material is carried by the substrate on the surface, with at least a portion of the pyrotechnic material contacting the bridge wire.
