Abstract

According to the invention a switching device (11) for an electric heating device is provided with a rod-shaped temperature sensor (15) formed by a ceramic rod (17) and an extension tube (16). The temperature sensor (16) operates a snap-action switch (22) located in a base (12) by means of an actuator separate from the said switch, which has at least one actuating part (41), which is loaded in the actuating direction by a leaf spring (34), the actuating part (41) and leaf spring (34) being in one piece. In a further development of the invention the leaf spring (34) or actuating part (41) can be a receptacle for an adjusting device, preferably an adjusting screw (38).
