ABSTRACT:
A light emitting push button for operating purposes, for instance a number button on a telephone apparatus, includes a body which is double-molded from two different plastic materials, of which one material is light conductive and the other is opaque. Light from a light emitting device, such as a light emitting diode, striking the underside of the push button is conducted through the light conductive material and is emitted on the upper side of the button. A slot is formed between the light conductive material and the opaque material on the upper side of the button, such that light conducted through the light conductive material will be scattered uniformly and be visible from all directions.
