Temperature controller

A temperature controller, in particular for electric heating elements of hobs, 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 the temperature, at least one switching system (4) having a switching spring (19) at a 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 switching system (4), wherein the switching spring (19), with an end (16.2) remote from its spring contact (21), is fastened to the switching spring base (16), wherein the switching spring base (16), at an end (16.1) remote from the fastening of its switching spring (19), is held securely and immovably on the temperature controller housing (5) and interacts with an adjustment element (24), one section or end (24.1) of which is held on a region (5.1) of the temperature controller housing (5) and another section or end (24.2) of which rests against the switching spring base (16), and by means of which, in order to adjust the switching point of the switching system (4), the switching spring base (16) together with the switching spring (19) can be moved relative to the expansion element (6) and/or to the actuating element (8) upon change of the distance between the region (5.1) of the temperature controller housing (5) and the 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 sections or ends (24.1, 24.2).
