ABSTRACT:
An electric detonator of delay type including leg wires connectable to bus wires, a capacitor connected across the leg wires for storing the electric energy supplied from an electric blaster via the leg wires, a delay circuit connected across the leg wires and generating an igniting signal at a predetermined timing, a switching circuit and an igniting resistor connected to the switching circuit, whereby the switching circuit is made conductive in response to the igniting signal to discharge the electric energy stored in the capacitor through the igniting resistor to explode the detonator. In order to operate the detonator reliably and safely, there are provided low and high voltage protection circuits for discharging the electric energy therethrough when the power supply voltage is out of a predetermined normal operation range.
