Abstract
An apparatus for electronically switching a detonation device is configured to arm an energy source upon receiving a first signal and discharge the energy source to the detonation device upon receiving and validating a second signal. An explosive device comprising a detonation device electrically coupled to an electronic switching device is also provided, wherein the switching device comprises a microcontroller configured to validate the first signal and the second signal. The detonation device may comprise a semiconductor bridge device configured to activate the explosive device upon receiving a charge across a first terminal and a second terminal from the switching device. Methods of operation are also disclosed.
