1. A thermal fuse, comprising:
a bow having a first end with a first soldering surface configured for soldering to a first contact surface of a printed circuit board and the bow having a second end with a second soldering surface configured for soldering to a second contact surface of the printed circuit board;
a tensioning element secured to the bow between the first and second ends, the tensioning element configured to press with a preload against the bow and the printed circuit board once the two soldering surfaces and the contact surfaces of the printed circuit board have been soldered;
wherein a portion of the bow between the two ends thereof comprises a measuring resistor connected in series to the two soldering surfaces; and
wherein the bow is arranged in a housing that has, on its underside, an opening through which the tensioning element extends.
