ABSTRACT:
A ratchet device for an electrical component that can be adjusted by rotation, such as a rotary switch or a rotary potentiometer, is provided. The ratchet device includes a leaf spring, resting against a ratchet contour by means of spring pressure, whereby the ratchet contour is applied on an outer side of a symmetrical ratchet disc. The leaf spring substantially encloses the ratchet disc, rests diametrically on the ratchet disc, and the ends of the leaf spring have an essentially radial embodiment, the leaf spring being otherwise free to move.
