<p>This device detects the overstepping of a predetermined temperature threshold, especially a low temperature threshold, and bars the subsequent use of this apparatus. It includes a temperature detecting element (12), capable of passing in a non-reversible manner from a first to a second stable state and delivering a warning signal when it is in this second state; and means of control, cooperating with the detector in order to deliver, in response to the warning signal, a signal for disabling the electronic apparatus. According to the invention, this temperature detecting element is an electrical element including a DC voltage source (15), an electrical or electronic component (17) able to take two states corresponding to the said first and second stable states and a thermostatic switch (16) which closes, for temperature values beyond the threshold, a circuit comprising the source and the component such that the flow of a current through the thermostatic switch prompts a transition from the first to the second state. <IMAGE></p> |
