A temperature-dependent switch having a switch housing, a temperature-dependent switching mechanism and a heating resistor component. The switch housing comprises a lower part made of electrically conductive material and a lid part which comprises a first section made of electrically conductive material and a second section made of electrically insulating material. The temperature-dependent switching mechanism comprises a movable contact part that establishes a first electrical connection between the lower part and a stationary contact part below a response temperature and interrupts the first electrical connection upon exceeding the response temperature. The heating resistor component is arranged inside the switch housing between the lid part and the lower part. The heating resistor component is electrically connected in series with the lower part and the first section of the lid part and electrically in parallel with the first electrical connection. The heating resistor component is arranged at a distance from the stationary contact part.
