Abstract (en)
[origin: EP2071274A2] The device has an ignition unit for transmitting ignition energy to another ignition unit, and a rotor (60) for interrupting the transmission of the ignition energy. The rotor is locked in a locking condition of a safety unit (62), which is provided to an unlocking action due to a physical unlocking parameter i.e. apogee parameter. The safety unit senses the apogee parameter, which is caused by fly through of a projectile over an apogee of a projectile trajectory. A locking unit (66) mechanically blocks the unlocking action in a safety location. The apogee parameter is selected from force, direction change of the projectile, lateral acceleration of the fuse, minimum in a longitudinal acceleration of the fuse, velocity of the projectile, or a direction of earth's magnetic field of the fuse.
