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 ...
A detonator is a device used to make an explosive or explosive device explode. [1] Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages. Types of detonators include non-electric and electric.
EWM has found its most common use as a detonator, named the exploding-bridgewire detonator, for nuclear bombs. Bridgewire detonators are advantageous over chemical fuzes as the explosion is consistent and occurs only a few microseconds after the current is applied, with variation of only a few tens of nanoseconds from detonator to detonator.

A modern multichannel radio remote detonator, in 2015. Detonation can be triggered from distant sources of interaction. This can be accomplished both by mechanical and electronic means. Electronic or electrical remote detonators use wires or electromagnetic radiation (such as radio waves or infrared light) to remotely command the device to ...
(A) Slapper detonator's pellet or flyer impacts a wider area of surface on the explosive output charge, and even though energy is lost to the sides of the area impacted, a cone of explosive is efficiently compressed. (B) EBW detonators only initiate a single point, and energy is lost in all directions, making the energy transfer less efficient.

This enabled percussion nose fuzes, but they had to cope with the spinning shell and centrifugal forces. This led, by about 1860, to percussion fuzes with a direct action firing pin and detonator and a magazine to boost the detonators sufficiently to initiate the shell's main charge. [9] Armstrong's time fuze designs evolved rapidly.
