A stun grenade for individual adjustment and situation-dependent adaptation of the number of active masses in situ. A switch mechanism is built into the stun grenade, enabling the simultaneous activation of different chambers inside the stun grenade in order to adjust the effect. The switch mechanism is formed by a tube and peripherally integrated boreholes and grooves. A different number of the chambers in the stun grenade is activated by the switch mechanism, thereby increasing or decreasing the active power.

The present invention is directed to a device for dispensing pyrophoric decoy particulates where the device is comprised of at least one payload vessel having a structural wall that forms a cavity for housing a plurality of pyrophoric particles. The structural wall has at least one opening to facilitate dispersal of the pyrophoric particles. The payload vessels are inserted inside a tubular sleeve and hermetically sealed inside the sleeve. Within the sleeve the at least one payload vessel is also in direct contact with an expulsion assembly that upon activation pushes the payload vessels and its pyrophoric contents out of the sleeve to react with the air.

The present invention concerns a coupling and power transmission system for an electric igniter, in particular for single-shot type fireworks (10), the system comprising a casing (11), in which the pyrotechnic components are housed, said casing having a first side that is open and a second side with a shaped connector (12), said shaped connector (12) comprising a channel (15) for connecting to said pyrotechnic components and adapted to removably receive an electric igniter (16), said electric igniter (16) being rigidly coupled to a printed circuit (18) on a PCB support (17), the printed circuit comprising two concentric tracks which are short-circuited via a connection track on a break-away tab (19) of the PCB support (17), whereby removal of the tab (19) eliminates the short-circuit, said shaped connector (12) being couplable, in a removable manner and with freedom of rotation with respect to an axis, to a docking base (13), said docking base (13) comprising the electronic components for transmission of an electrical signal to said electric igniter (16) and in particular three contacts (20), aligned with each other and dimensioned in relation to said printed circuit (18), ensuring connection between the tracks of said printed circuit (18) and the contacts (20) independently of the angular position of said shaped connector (12) with respect to said docking base.
