Abstract

A device for connecting and disconnecting a current supply (1) to an electric circuit (2) dependent on the ambient temperature. In a housing, the device includes a current conducting element (4), a temperature sensing switch (5) and a heat conducting material (6) being, at least partly, a fluid. When the switch (5) is closed the current conducting element (4) is emitting heat delivered to the temperature sensing switch (4) by the heat conducting material (6), the switch disconnecting the current attaining the breaking temperature. The operation is repeated as long as the ambient temperature is below the breaking temperature of the switch.
