Abstract

A device for emitting an electrical signal for furniture, especially for refrigerators or freezers, is provided with a sensor for determining whether a door is closed or open. In order in this case to avoid mechanical adjustment work to compensate for manufacturing tolerances and type scatters, a magnetically sensitive sensor is arranged in or on the furniture, which sensor is acted on by a magnetic field of a magnetic transmitter provided there, when the door is closed, and controls a signalling device, which is connected downstream of it, such that a warning signal is emitted, if necessary delayed in time, even if the door is slightly open.
