An apparatus for detecting a number of revolutions of a rotatable shaft, is proposed, which apparatus encompasses a magnet disposed on the shaft, and a micromechanical device. A detection element of the micromechanical device, which element interacts with the magnet, is advanced stepwise upon each movement of the magnet past the micromechanical device in accordance with the movement direction of the magnet. |
