Abstract

An electric fired pyrotechnic grenade, e.g. for the generation of a smoke screen, comprising propellant and disperser charges ignitable by an electric squib. In the inoperative state the squib terminals are short-circuited whereby any unintentional firing by stray currents is pre­ vented. Preferably a Faraday Cage is provided to shield off the squib against radio frequency interference. It is further preferred to pack the disperser charge within an axial, perforated tube.
