Method for adjusting a proximity switch and proximity switch

Abstract

A switch and method for adjusting the switching threshold of a contactlessly operating proximity switch comprising a sensor for converting a physical variable into an electric sensor signal S(x), a control unit for evaluating the electric sensor signal S(x) and for generating a binary switching signal by comparing with a switching threshold Sein, and comprising an operating element for adjusting the switching threshold Sein according to a control value P, wherein the control value P is mapped in a non-linear manner on the movement path of the operating element, wherein the resolution of the operating element is largest when the electric sensor signal S(x) is in the vicinity of the switching threshold Sein(P) and decreases in a non-linear manner at increasing distance such that the influence of the switching threshold Sein(P) is fine in the vicinity of the current sensor signal S(x) and increasingly coarser at increasing distance.
