A method and a control unit () for controlling a supply of power to an electrical circuit comprising a switch (). An output voltage of a first power source (), which is connected to the circuit, is measured and compared to a predefined threshold voltage. If the measured voltage is smaller than the threshold value it is determined that the switch () is in a closed state, and if the voltage is larger than the threshold value it is determined that the switch () is in an open state. The supply of power is controlled in accordance with the open/closed state of the switch (). Preferably, the electrical circuit is connected to a second power source () when the switch () is in a closed state. Power is conserved while it is ensured that sufficient power is available when needed. The invention is very suitable for supplying power to a lamp () positioned inside a refrigeration compartment (), especially when the system is battery powered.

Intelligent lighting supply

A refrigerating apparatus for a refrigerator has an electrical voltage supply and an electrical interface for connection with components of the refrigerator with the interface having a galvanic isolation between an input arrangement connected with the refrigerating apparatus and an output arrangement connected with at least one component of the refrigerator.

Refrigerating apparatus and refrigerator

A cooling medium compressor arrangement is comprised of a compressor, a control mechanism electrically connected with the compressor, and a gas sensor, and the safety of the arrangement is improved by arranging the control mechanism and the gas sensor in a common housing.
