A detonator is a small piece of equipment used to make a bomb, a mine, or other explosives go off. It is not the bomb. It is the part that starts the explosion — with a spark, a shock, or a timer. You will meet it in news about attacks, in mining, and in films. In ordinary life you rarely need the word. Though actually, older railways also used a small explosive detonator on the track as a warning bang for the driver — same idea: a small charge made to go off on purpose. Do not call the whole bomb a detonator.
