Abstract
An electric actuated explosion detonator for use to detonate a confined explosive charge capable of being detonated by heat and/or shock, including an electrical resistor positioned in engagement with the confined explosive charge, the resistor having two electrical contacts and having a predetermined maximum electric current carrying capability and subject to receiving, by the application of an electrical energy source, sufficient voltage and wattage that an instantaneous current flow causes the resistor to instantaneously disintegrate.
