Electronic time delay fuse

A time delay fuse assembly comprising:

• a housing containing an initiator, an electronics board including a circuitry and a power supply, the initiator configured to release explosive energy;
• a first contact pin having a non-conducting position wherein the circuitry is not electrically connected to the power supply and an electrically conducting position wherein the circuitry is electrically connected to the power supply, the first contact pin being configured to shift from the non-conducting position to the electrically conducting position in response to the release of explosive energy by the initiator;
• and
• a detonator contact pin configured to convey a signal from the circuitry to a detonator, the circuitry being configured to produce a time-delay period that begins to run when the first contact pin shifted to the electrically conducting position and to send the signal to the detonator upon completion of the time-delay period.
