The network arrangement includes at least one common bus. An input member is connected to the common bus. An output member is connected to the common bus. The input member comprises at least one input contact defined with a unique identity. The output member comprises at least one output contact defined with a unique identity. The input member is adapted to receive an input signal through the at least one input contact. The output member is adapted to provide an output signal through the at least one output contact. The input member is arranged to generate an action signal transmitted over the buss from the input member to the output member. The action signal comprises an address corresponding to the unique identity of an output contact.
