Abstract (en)

[origin: US4690056A] An electric detonator device including an insulating carrier member carrying an ignition bridge and first and second electrodes connected to the ignition bridge. At least one of the electrodes is provided in the form of a layered conductor path configured to provide a high-frequency filter so as to prevent high-frequency interference signals from passing to the ignition bridge and causing misfiring.
