: Triggered by an electric current sent through wires from a remote switch.
A , commonly referred to as a detonator or blasting cap , is a specialized component used to trigger high explosives. Because high explosives (like TNT or dynamite) are designed to be stable and safe to handle, they require a specific shockwave or intense heat provided by a detonator to begin the chemical reaction. Key Functions detonating device
: Uses a hollow plastic tube that carries a low-energy dust explosion to the detonator. : Triggered by an electric current sent through
: Acts as the first step in a " detonation train ," turning a small signal into a powerful enough force to ignite the main charge. Key Functions : Uses a hollow plastic tube
: Provides a way to ignite explosives from a safe distance using electrical signals, shock tubes, or fuses. Common Types
: Many detonators include "delay elements" that allow for precise timing between multiple explosions, essential for controlled mining or building demolition.
Due to their sensitive nature, detonators are strictly regulated by government agencies like the ATF in the U.S. and equivalent global bodies: Module 2 - Initiation Systems
