ABSTRACT:
An electronic igniter circuit for an electric primer for the detonation of a pyrotechnical charge comprising a controlled semi-conductor element connected to the primer and a source of electrical energy to fire the primer when the semi-conductor element is rendered conductive. A condensor is connected in parallel to the source and the primer and a checking circuit for verifying the integrity of the igniter circuit and its elements is connected in parallel between the condensor and the primer. The checking circuit includes a voltage sensor which can be connected as a unit with the primer and connected via a cable to the igniter circuit at a remote location.
