Detonators contain an explosive train that is a miniature version of the larger explosive system.
The delay element in turn ignites a primer charge, which undergoes a transition from deflagration to detonation and initiates the main or output charge. Detonators may or may not include the delay feature. Electric detonators are activated by passing an electrical energy pulse through a bridge wire that is embedded in the ignition charge or primer spot. Electric detonators may be further classified as electric instantaneous, electric delay, electronic, toroid-type, and exploding bridge wire. All are produced with numerous delays, wire lengths, wire colors, and wire configurations.
