ABSTRACT:
An electric hotplate with a cast member has a downwardly-directed border on its outer periphery. The edge of a covering sheet centrally fixed to the hotplate by a hollow screw rests on the lower edge of the border. A covering sheet step is centered within the border. A moisture-proof closure is obtained through an interposed seal and insulation is provided by a crinkled aluminum foil. The hot plate connecting leads are passed via an insulating member through the covering sheet which, peripherally displaced by 180.degree., faces a depression in the covering sheet so that hot plates according to the invention can be stacked in a space-saving manner. The connecting leads are flexible and their ends are brought together in a common connecting member.
