Abstract

An igniter (100), for igniting explosives or pyrotechnic composition, comprising a container (102) for housing explosives or pyrotechnic composition (102a); and an electronic circuitry (104) comprising, two conducting electrodes (106), each having a first end (106a) and a second end (106b). Each first end (106a) is located inside the container, electromotive force, EMF, source, (108). Each second end (106) of the electrodes being arranged to be connected to the EMF source (108), and a control circuit (110). Said control circuit is configured to, based on obtained data, determining if a predetermined conditions is fulfilled, and the control circuit is arrange to connect the EMF source 108 with said each second end (106b) of the conducting electrodes (106). Each first end (106a) of the conducting electrodes (106) is arranged to, upon obtaining EMF, provide energy into said container (102). The container (102) and the electronic components of the electronic circuitry (104) are at least partly integrated.
