Abstract: The invention relates to a novel method of producing a resistor device comprising a PTC-polymer element 2 and a varistor element 4. Both elements are moulded in a common moulding process using one common mould. Preferred is co-injection moulding. The invention further relates to the resistor device thus produced and a current limit means including this resistor device and a switch (fig. 4).
