The invention relates to an actuator with a housing () in which a piston () with a pin () is inserted in a longitudinally displaceable manner, and with an igniting element () with contact pins (), wherein the contact pins () project out of the housing () on the connecting side () thereof, and, when the igniting element () is ignited by the propellants generated, the piston () is displaced in the direction of the actuating side () until the pin () projects out of the housing () on the actuating side (). For production to be more cost-effective, it is proposed that the housing () is designed as a single part and in the form of a cylinder, and the connecting side () is injection moulded or bonded around the end surface () of the housing () with a cylindrical cover () fitting thereover.

Pyrotechnical actuator

An ignition system for projectiles, such as shells, bombs, or rockets is disclosed. The system has a pressure chamber defined by a double-diaphragm switch and a cap of a deformable material. The diaphragm of the double-diaphragm switch, which defines one wall of the pressure chamber, contains one or several perforations, the number and diameter of which depend on the spacing of the diaphragms, the areas thereof and the size of the pressure chamber. The double-diaphragm switch is connected to an electric ignition unit. An electrical circuit is closed only if a projectile housing a percussion fuse and the ignition system impacts on the ground or target after its flight. Any unintended ignition during firing or due to brief impact stress cannot occur.
