Abstract
A detonator assembly for initiating an explosive comprises a power source, an initiator, and a switch coupled between the power source and initiator. The switch has a trigger input responsive to a stimulus to activate the switch, where activation of the switch causes electrical energy to be provided to the initiator. The stimulus comprises at least one of a clock-based stimulus, a pressure stimulus, a light stimulus, an acoustic stimulus, and a vibration stimulus.
