Arrangement and method for deactivating electrical elements when malfunctioning

Arrangements (1) are provided with electrical elements (11,21) for, in a feeding mode, receiving feeding signals and, in a non- feeding mode, not receiving the feeding signals, and with circuits (12,22) for, in the feeding mode, detecting malfunctions of the electrical elements (11,21). The circuits...

More Information
Summary:Arrangements (1) are provided with electrical elements (11,21) for, in a feeding mode, receiving feeding signals and, in a non- feeding mode, not receiving the feeding signals, and with circuits (12,22) for, in the feeding mode, detecting malfunctions of the electrical elements (11,21). The circuits (12,22) comprise active switches (13,23) for, in response to detection results, deactivating the electrical elements (11,21) in both modes, in other words in the feeding mode as well as the non- feeding mode. The electrical elements (11,21) for example comprise light emitting diodes, incandescent lights or loudspeakers etc. The active switches (13,23) for example comprise bistable micro-relays or semiconductor switches such as non- volatile power semiconductor switches such as one time programmable flash power MOSFETs etc. Preferably, the arrangements (1) are integrated arrangements.
