<p>An inductive programming switch for applications in special environments, comprising an inductive component and a container in which the inductive component is accommodated proximate to a wall of the container, the inductive component being connected to an electronic evaluation circuit, which is adapted to detect variations of parameters of the inductive component caused by the approach of a metallic object to the wall, the evaluation circuit being adapted to detect and identify a sequence of approach/spacing of the metallic object with respect to the wall and for modifying its functional parameters according to the sequence.</p> |
