ABSTRACT:
In a glass mounting plate, which is provided on the underside with a partly transparent and partly non-transparent mask, is fitted an electric hotplate. An illuminating chamber illuminating by a lamp is connected to its underside. The mask gives rise to a marginal area through which light shines to the outside for indicating the operating state of the hotplate. The mounting plate can also be made from non-transparent material, such as sheet metal. The light then passes through a permeable seal or other transparent mounting components.
