The paper presents the constructions of new, fast-acting electric initiating blasting caps of WN-1 and WN-1A types, developed at the Military Institute of Armament Technology in Zielonka (Poland). These blasting caps have been characterized in terms of the materials used for their production and the applied explosives. The investigation results of selected blasting caps and their most important characteristics are given. Among others, dependence between a response time of a blasting cap and a supply voltage was presented as well as influence of extreme temperatures on its reliability and response time was given. The investigations of the blasting caps for initiation of blasting explosives were performed and the results confirming their usefulness are presented.
