A detonator is a device used to trigger an explosive reaction. It initiates the explosion by providing a small amount of energy, often through an electrical signal or a shock wave. Detonators are essential in various applications, including construction, mining, and military operations, where controlled explosions are necessary. There are different types of detonators, such as electric detonators and non-electric detonators. Electric detonators use an electrical current to ignite the explosive, while non-electric types rely on shock waves from a separate explosive charge. Both types are designed to ensure safety and precision in handling explosives.
