Inductive couplings for, for example, electrically coupling electrically initiated explosive devices. An electric coupling includes a transformer having primary and secondary windings, (12, 11, respectively), which may, for example be mounted for relative rotation or linear displacement means for moving or permitting the movement of the primary or secondary winding, between a first position wherein in use there is substantially no inductive coupling between the windings, and a second position wherein inductive coupling between the windings is maximised. |
