The central part passes through a recess in a primary unit in the explosive first side. Its side located against the explosive other side supports a second unit (3b) which can be moved along the central part by threads (1b,3a). The central part encloses a main ignition unit, initial or booster (6) which extends into both the units. The end surfaces (14,3c) on the units work with a retentive function with the explosive side surfaces adjacent to the through hole(4). The first unit supports two or more inclined electric igniters (15), the longitudinal axes of which cross the central parts of a surface (8a) on an explosive capsule (8). This capsule ignites the main initiator. The tubular part has a thinned wall surface counterposed to an inner edge surface (5d) on the explosive or iniation chargers (5). This is broken through when the main initiator (6) is ignited with the explosive capsule (8). |
