Temperature limiter, and calibration method for operating a switching contact of a temperature limiter

A temperature limiter, comprising:

• a switch head including at least one switching contact;
• a temperature sensor including elongate expansion elements which have different thermal expansion coefficients and are defined by a switch head distal first end zone where the expansion elements are fixed immobile relative to one another, and a switch head proximal second end zone where one of the expansion elements is movable relative to the other expansion element;
• a ram slidably supported in the switch head and abutting against the movable expansion element, with the ram having an end portion which is situated in an area of the switching contact and constructed to allow application of a process selected from the group consisting of welding and soldering;
• and
• a switch sleeve placed over the end portion of the ram and adapted for actuation of the switching contact, wherein the switch sleeve is movable relative to the ram during a calibration phase, until reaching a position which is determinative for calibrating a desired response temperature of the switching contact and in which position the switch sleeve is securely fixed to the end portion of the ram through a process selected from the group consisting of fusion welding and soldering.
