The Inductive Selective Switches can differ ferrous-magnetic metals (e.g. iron, steel) from non-ferrous-magnetic metals (aluminium, brass, copper and stainless steel). Metals influence the LC-oscillator below the active surface of the Selective Switch trough their specific electromagnetic characteristics and thus can be differd.
