A detonator (10) is equipped with an input lead (29) having multiple signal transmission lines (30, 31) which provide redundant initiation signals to the target charge (14) of a detonator (10, 10') thereby increasing the reliability of initiation. The multiple signal transmission lines (30, 31) may be made of shock tube and can be part of a long or short input lead (29, 129) and may be initiated by any suitable means, for example by being disposed in signal transmission relation to a detonating cord (60, 62) to improve the reliability with which a signal is transferred from the detonating cord (60, 62) to the detonator (10, 10').

[ What is claimed is:] [1.] A detonator having an output section and comprising:a shell defining an enclosure;a target charge comprising at least an explosive output charge disposed within the shell at the output section of the detonator; andan input lead extending into the detonator and secured therewithin, the input lead having at least two signal transmission input lines which extend into the shell and terminate in signal-emitting ends disposed within the shell in signal transmission relation with the target charge.
