Abstract
A detector arrangement included in an electric circuit arrangement which includes a stand by shut down and which comprises a first power supply () which is connected to mains voltage and which converts the mains voltage to a first voltage adapted for an electric motor () included in the electric circuit, the first power supply being, by means of a supply conductor () across a switch () by which the electric circuit may be closed or opened, is connected with its positive pole () to said motor, and the motor is, by means of a return conductor (), connected to the negative pole () of said first power supply, as well as a control circuit () which, on the one hand, is connected via a first signal conductor (), to the first power supply and, on the other hand, to an included second power supply () which feeds the control circuit with a second voltage which is substantially lower than the first voltage and which, with its negative pole, is connected to the return conductor, and detector means for registering the state of the switch, said means being connected to the control circuit for control thereof by the first power supply between the energised state in which the switch is in the on position and in which the power supply emits voltage, and a shut down state in which the switch is in the off position and in which the power supply emits no voltage where the detector arrangement includes a resistor () and a first diode () which are connected in series and are included in a crosswire.
