Electric detonator (blasting cap)

A metal-shell initiating device containing a bridgewire assembly, primary explosive (lead azide), and output charge (PETN or RDX). Firing current through the bridgewire heats the primary explosive, initiating the output charge and producing a detonation wave at the base of the shell.
