Detonator

A detonator is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the latter two being the most common.

 The commercial use of explosives uses non-electric or electric detonators. Many detonators' primary explosive is a material called Lead Azide pressed into place above the base charge, usually PETN.

 Delay detonators have a pyrotechnic delay train above the primary charge. This provides a time delay between the firing of the downline and the detonation of the base charge.
