Electromechanical temperature detection device for a cooking appliance and method for the manufacture of an electromechanical temperature detection device

An electromechanical temperature detection device for a cooking appliance, comprising:

• a first, elongated sensor part having a first longitudinal axis comprising a first material with a first thermal expansion coefficient;
• and
• a second tubular-like sensor part comprising a second material with a second thermal expansion coefficient comprising a stamped sheet metal part having a first longitudinal edge and a second longitudinal edge to form a tubular shape having a second longitudinal axis,
• wherein said first longitudinal edge of said second tubular sensor part interlocks with said second longitudinal edge,
• wherein said first elongated sensor part is positioned within said tubular shape of said second sensor part so that said first longitudinal edge aligns and is in contact with said second longitudinal edge and said first elongated sensor part is at least partly surrounded by said second sensor part,
• wherein a first end of said first sensor is affixed to a first end of said second tubular-like sensor part and a remaining portion of said first sensor part is allowed to move relative to the second sensor part along the first longitudinal axis during expansion of said first sensor part, and
• wherein a second end of said second sensor part is affixed to a switching device such that said first sensor part, upon expansion, is configured to cause said switching device to interrupt a circuit at a preset temperature.
