Electronic time-fuse for a projectile

Electronic projectile time detonator with an electronic control unit (3), which with a first input (Up) is connected to a programming interface (12, 15) for the input of a time program, with a voltage regulator (2) which supplies the electronic control unit (3) from programming information or via an acceleration-activated battery (1) at a second input (Uv) with voltage, and with a mechanical safety device (9, 10) which enables an ignition stage upon its activation, characterized in that a switch (5) actuated by the mechanical safety device (9, 10) is disposed, which connects the input of the voltage regulator (2) with a third input (Us) of the electronic control unit (3), with a finishing out of the time program becoming only possible with the actuated switch (5).
