Abstract

Zünder mit einem zwischen Zündhütchen (6) und Detonator (9) angeordneten pyrotechnischen Ver­ zögerungssatz (7) und einer Durchschlagsicherung (8), die bei vollständiger oder teilweiser Abwesenheit des Verzögerungssatzes (7) eine Zündübertragung vom Zündhütchen auf den Detonator (9) verhindert. Die Durchschlagsicherung (8) besteht aus einem entflamm­ baren oder thermisch zersetzbaren, weitgehend ohne feste Rückstände verbrennenden oder sich thermisch zersetzenden Feststoff. Detonator with a between primer (6) and Detonator (9) arranged pyrotechnic Ver delay rate (7) and a breakdown protection (8) in the event of complete or partial absence the delay set (7) an ignition transmission from Prevent the detonator (9). The Breakdown protection (8) consists of an ignition ed or thermally decomposable, largely without solid residues burning or getting thermal decomposing solid.
