Centralized control system for an aircraft cabin

An assembly for an aircraft cabin in which a plurality of seat units is installed comprising:

• a plurality of electronic control units each being associated with a seat unit, each electronic control unit being capable of controlling electrical equipment associated with a corresponding seat unit, wherein said assembly further comprises:
• a centralized control system comprising a power line on which a centralized control signal is intended to circulate, said power line being relayed from one seat unit to another inside the aircraft cabin;
• and
• a plurality of switching devices each being associated with a seat unit, each switching device having an input connected to the power line and an output connected to a corresponding electronic control unit, each switching device ensuring galvanic isolation between the power line and the output of the switching device connected to the electronic control unit,
• each electronic control unit being able to control a functionality of a corresponding seat unit according to a state of the output of the switching device, a change of which is induced by the centralized control signal, such that a functionality can be controlled simultaneously for all the seat units in the aircraft cabin via an emission of the centralized control signal.
