Abstract: A reed for use in a reed-type switch comprising a body of magnetic material having a contacting surface essentially made up of a precious metal with some of the body material diffused therein, and an interface layer of an alloy of the precious metal and the body material between the body of magnetic material and the precious metal layer. The magnetic material is a glasscompatible nickel-iron alloy containing from about 0.125 to about 0.250 manganese by weight percent and having a resistivity not greater than about 225 ohms per circular mil foot.
