detonator

A detonator is a specialized device used to trigger an explosion. It contains a small, reliable initiating charge that, when activated—often by electricity, shock, or friction—sets off a larger explosive or explosive assembly. Detonators are essential in mining, demolition, and military applications to ensure controlled and precise explosions. They are designed to be safe to handle under normal conditions but reliably activate when intended, providing a critical link between a trigger signal and a powerful explosive reaction.
