FIELD: the invention is designed for bringing into action of electric spark igniters of ammunition detonating devices of various purposes at their impact with a barrier(target). ^ SUBSTANCE: the essence of this invention is that an impulse electromagnetic oscillator has firmly fixed together a tubular cylindrical constant magnet, a yoke consisting of a core with basis in the shape of a disk, a coil with winding. The armature is made graded in the form of two cylinders of different diameters. The smallest cylinder is placed coaxially within coil with winding and magnet and sides with yoke's butt-end forming clearance in the middle section of the winding. A ring of m-metal is inserted between the lower surface of the large cylinder and magnet's butt-end. A gage block of non-magnetic material is installed between the yoke core's butt-end and armature. ^ EFFECT: increases reliability of oscillator's functioning at placing in any part of ammunition, ensures instant blowing up at concussion with a thin metallic barrier; high noise immunity. ^ 3 cl, 1 dwg |
