A detonator is a device used to make an explosive or explosive device explode. [1] ... Cutaway diagram of various types of blasting caps and detonators.
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
Diagram of a slapper detonator. A slapper detonator, also called exploding foil initiator (EFI), is a detonator developed by Lawrence Livermore National Laboratory, US Patent No. 4,788,913 (Filed 1971, Granted 1988). It is an improvement over the earlier exploding-bridgewire detonator.

The following diagrams show the SMi-35 mine's internal mechanism, together with the three-pronged pressure fuse. The safety pin for the fuse and the three removable plugs for the detonators are clearly visible. These diagrams were issued as part of a US Army field manual on mines in 1943.
The original M18 Claymore mine. The detonator is inserted into the side. In 1954 Picatinny Arsenal issued a request for proposals (RFP) to improve the M18 as a more effective weapon. At Aerojet in the early 1950s, Guy C. Throner had independently come up with a design for a Claymore-like mine. He worked with Don Kennedy and the two men ...
Nonel shock tubes (pink, red, orange, yellow) with Orica surface delay connector (blue) in use. Nonel is a shock tube detonator designed to initiate explosions, generally for the purpose of demolition of buildings and for use in the blasting of rock in mines and quarries.
The idea of a proximity fuse had long been considered militarily useful. Several ideas had been considered, including optical systems that shone a light, sometimes infrared, and triggered when the reflection reached a certain threshold, various ground-triggered means using radio signals, and capacitive or inductive methods similar to a metal detector.
