Detonating: Device

: Triggered by an electric current sent through wires from a remote switch.

: Uses a hollow plastic tube that carries a low-energy dust explosion to the detonator.

: High-tech versions used in mining that use microchips for extreme precision in timing. Safety and Regulation

: Acts as the first step in a " detonation train ," turning a small signal into a powerful enough force to ignite the main charge.
