An electronic detonator (1) which comprises an ignition charge, a battery unit (19) for emitting igniter current for initiating the ignition charge, and an electronic circuit (4) for controlling said emission of igniter current. The battery unit (19) is movable in the detonator between a resting position and an activated position, in which the battery unit is connected to emit said igniter current. Battery activating means (25, 28) are provided, in response to external activation (3), for pyrotechnically causing the battery unit (19) to move from the resting position to the activated position. |
