Temperature controller

A temperature controller comprising:

• a temperature controller housing (5),
• a temperature sensor (2) with an expansion element (6) which generates a movement stroke in a direction of action (AT) as a function of temperature,
• a first switching system (4) having a first switching spring (19) at a first switching spring base (16) on which the expansion element (6) or an actuating element (8) moved by said expansion element acts in order to switch the first switching system (4), wherein
• the first switching spring base (16) has a first end (16.2) of the switching spring base (16) on a first side of the expansion element (6) or the actuating element (8) and a second end (16.1) on a second side of the expansion element (6) or an actuating element (8) and a spring contact (21) disposed on the first switching spring (19) and the first switching spring base (16) is fastened to the first switching spring (19) at a point of attachment, wherein
• the first switching spring base (16), at the second end (16.1) is disposed on the temperature controller housing (5) and the first switching spring base (16) interacts with an adjustment element (24), one end (24.1) of said adjustment element disposed on a region (5.1) of the temperature controller housing (5) and a second end (24.2) of said adjustment element disposed against the first switching spring base (16), and
• by means of which, in order to adjust a switching point of the first switching system (4), the first switching spring base (16) together with the first switching spring (19) can be moved relative to the expansion element (6) and/or to the actuating element (8) upon change of a distance between the region (5.1) of the temperature controller housing (5) and the first switching spring base (16), characterized in that the adjustment element (24) is an elongate element having a longitudinal direction (A), wherein the adjustment element (24), for adjusting in an adjustment direction (J), can be permanently deformed transverse to its longitudinal direction (A) upon change of the distance between the first end (24.1) and the second end (24.2).
