Temperature-limiting device

An electric heater (2) adapted for location behind a surface (4) to be heated and comprising a dish-like support (6) having therein at least one electric heating element (12) having a first terminal region (12A) and a second terminal region (12B), and a temperature-limiting device (14) having a thermally responsive bimetallic means (22) provided in a housing (16), the housing (16) being adapted to be supported at a peripheral region of the heater (2), at least partially externally of the dish-like support (6), the thermally responsive bimetallic means (22) being adapted to be thermally coupled with the heater (2) to sense heat generated therein by the at least one heating element (12) and to respond at a predetermined temperature to operate at least one switch means (18) located in the housing (16), the housing (16) having a first side (32) and a second side (38) opposite to each other provided with a first electrically conductive element (34) and a second electrically conductive element (40) accessible at the sides (32, 38) of the housing (16), externally of the dish-like support (6), wherein the first and second terminal regions (12A, 12B) respectively of the at least one electric heating element (12) are electrically connected to the first electrically conductive element (34) and the second electrically conductive element (40).
