Electric water-boiling container having switch-on dry and stream sensitive thermally responsive control units

An electrically heated container for boiling liquids provided with a thermally sensitive electrical control including a switch-on-dry protector switch unit enclosed in a protective housing and making direct electrical connection with the cold leads of an electric heating element located externally on said container in heat exchange relation thereto and including thermally sensitive switch means effective, in use, to interrupt the electrical supply to said heating element;

• terminal pins carried by and projecting from said protective housing of said protector switch unit and adapted to be engaged by a female socket connector whereby electrical connection of said heating element to a main supply can be made, said protector switch unit being mounted on a mounting plate, said mounting plate being located within a detachable base member and externally of said container in thermal contact with said heating element;
• said mounting plate conducting heat to said switch unit to cause said switch means to operate and interrupt said electrical supply to said heating element should the element overheat when the container is switched on dry, said switch means also operating should the element overheat when the container is boiled dry.
