Patent ID: 7193192

Claim:
An electric heater ( 2 ) adapted for location behind a surface to be heated and comprising a dish-like support ( 6 ) having therein at least one electric heating element ( 12 ) having a first terminal region ( 12 A) and a second terminal region ( 12 B) and a temperature-responsive device ( 14 ), wherein the temperature-responsive device comprises an electrical component ( 18 ) having an electrical parameter which changes as a function of temperature and arranged to be supported inside the heater ( 2 ) by an elongate member ( 16 ) which is adapted to be secured to the heater ( 2 ) and to extend at least partially across the heater ( 2 ) from a region externally of the periphery thereof, an electrically insulating carrier member ( 30 ) being secured to the elongate member ( 16 ) at a location externally of the periphery of the heater ( 2 ), the carrier member ( 30 ) having a first side edge ( 32 ) and a second side edge ( 38 ) laterally disposed at opposite sides of the elongate member ( 16 ) and provided with a first electrically conductive element ( 34 ) and a second electrically conductive element ( 40 ) accessible at the opposite side edges ( 32 , 38 ) of the carrier member ( 30 ) for electrical connection to the first and second terminal regions ( 12 A, 12 B) respectively of the at least one electric heating element ( 12 ).
