Abstract
Procedure to produce the delayed firing of explosive charges characterized by comprising passing an electric current of ignition through the fuze or fuse of each successive detonator and by means of an electrically actionable delay switch inserted between it and its preceding detonator to allow that the electric current of ignition passes through said fuse or fuze when a closed circuit is formed by the action of the mentioned switch.
