1. A wireless electronic detonator comprising:
an on-board primary source of energy,
at least one functional module,
a power switch disposed between the on-board primary source of energy and said at least one functional module, the power switch configured to connect or disconnect said at least one functional module and the on-board primary source of energy, and
a controller to control the power switch,
wherein said at least one functional module comprises at least one explosive fuse and an energy storage element dedicated to an ignition of said at least one explosive fuse, and the on-board primary energy source is configured to transfer energy to the energy storage element via the power switch; and
wherein the controller comprises an optical receiver configured to detect and demodulate a light signal emitted by a control console and the controller generates at an output a control signal according to the demodulated light signal, the control signal being configured to at least control the power switch.
