The present invention relates to a device at an inductive sensor for achieving a displacement, dependent on the rotation speed, of the ignition preset in an electronic ignition system at combustion engines. The device comprises a coil (5), a magnet (3, 8), rotating in relationship to the coil, which magnet creates a ramplike voltage in the coil and a thin sheet (7) made from a magnetic material influencing the magnet field such that the moment of time for achieving a certain voltage in the coil (5) is displaced. The thin sheet (7) is mounted at the coil and extends from same into the magnet field. Hereby the think sheet extends perpendicularly to the central axis of the coil or forms an angle, deviating from 90 degrees from same. |
