Abstract
A temperature limiting user interface comprises a potentiometer for providing a reference signal to an electronic apparatus, the electronic apparatus being adapted to generate heat as a function of the reference signal; and a temperature-sensitive impedance, thermally coupled to the electronic apparatus so as to receive at least a portion of the heat, and electrically coupled to the potentiometer so as to alter the reference signal as a function of temperature.
