Abstract

The temp monitor (10) has a heating resistance (23) associated with the overtemp switch (15) for providing a self-holding function. The heating resistance is provided on a foil (22) providing electrical and/or thermic insulation. Pref. the foil is coated on one or both sides with a cold conductor resistance material providing a printed resistance path, or is provided as a heating foil with an insulating plastics foil layer and a resistance conductor.
