ABSTRACT:
A tubular electrical element lying substantially in a plane is fixed under a heater plate of an electrical appliance. The ends of the element are connected to a thermal limiter disposed near the middle of the element to measure at least the temperature of the element and to disconnect the electrical power supply from the element if the measured temperature exceeds a predetermined value. A portion of the element extends substantially along the peripheral contour of the plate and the ends of the element extend towards the middle of the element.
