Abstract
The invention relates to a device for detecting movements and/or positions of an object with the aid of voltage pulses induced by the field of adjacent magnets () in a coil (). In order to generate a sufficiently strong signal also at small relative speeds between the magnets () and the coil (), the coil () encloses a spring () in which a quick fore-and-aft movement can be induced by the magnetic fields of the magnets (), the magnetic poles of the spring () being reversed during said fore-and-aft movement.
