This patent discloses a conductor plated on a frangible substrate. The unit is potted in a silicon base compound, placed in a header, and attached to a printed circuit board. This assembly is then encased in a housing using epoxy resin potting compound. The circuit is protected from breakage due to mechanical shock by the epoxy resin but is immediately broken by an explosive shock wave which fractures the substrate and the conductor and opens the circuit.
