Abstract (en)

[origin: US2002149465A1] A temperature limiter includes a switch head with a switching contact and a temperature sensor having elongate expansion elements of different thermal expansion coefficients. The expansion elements are fixed relative to one another in one end zone and movable relative to one another in the other end zone. Slidably supported in the switch head is a ram which abuts against the movable expansion element and has an end portion constructed to allow application of welding or soldering. A switch sleeve is placed over the ram end portion and adapted to actuate the contact. 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. In this position, the switch sleeve is then securely fixed to the end portion by fusion welding or soldering.
