Patent ID: 8368503

Claim:
A temperature sensor with a housing, said temperature sensor comprising: a first expansion element connected to said housing and being in a form of a tube and containing a second expansion element in a form of a rod, said first and said second expansion elements having different coefficients of thermal expansion; a first switching spring being pre-stressed and comprising a switching contact, said rod acting on one side of said switching spring; and a second switching spring provided in a direction of said rod or of an intermediate element as an extension of said rod, said second switching spring fastened to a second switching spring base, wherein said second switching spring base is configured to be movable along a longitudinal direction of said rod thereby adjusting a switching point of said second switching spring, wherein locking means fixes a position of said second switching spring base, wherein said second switching spring base is elongated and is connected to said second switching spring in an end region of said second switching spring, wherein said end region is remotely positioned from a switching contact of said second switching spring, said second switching spring base fixed in an unalterable manner to another end region to said temperature sensor housing, and wherein an adjustable locking arm is provided in said end region between said second switching spring and said second switching spring base, wherein said locking arm is fixed to said temperature sensor housing or to a part fixed in said temperature sensor housing in a particular position.
