The electric radiant heater ( 1 ) adapted to a cooking hob is attached to the cooking plate ( 2 a) forming with it an air cavity ( 13 ) inside which the extended heating resistor ( 5 ) is housed on an insulating base ( 4 ). A peripheral insulating ring ( 6 ) and an outer metal tray form a peripheral external wall ( 3,6 ) defining said cavity ( 13 ) in which there is positioned a bimetal thermal switch ( 7 ), which has a compact body ( 7 a) resting on the surface ( 4 a) of the insulating base, and a heat receiver base ( 7 b) in a position facing a part of the heating resistor ( 5 ). The position of the compact body ( 7 a) relative to the heating resistor ( 5 ) is determined so as to obtain an actuating temperature point (SWC, SWO) adjusted for switching a hotplate warning light on and off.
