Safety disconnection device for electrical users, in particular for use in smoothing irons and portable heaters. It comprises a thermal switch (1) with another switch (22) connected in parallel with the user (R), a dropping resistor (R1) for the other switch (22) heating the thermal switch (1), also connected in parallel with the user (R), and another resistor (R2) which permanently short-circuits and heats the thermal switch (1). |
