Method for recognising the wiring of an assembly of at least two dimmer switches (10, 20, 30), referred to as the first dimmer and second dimmer, each dimmer (10, 20, 30) comprising at least one transistor (12, 22, 32) and an output (14, 24, 34), the second dimmer also comprising a voltmeter, the output of the first dimmer being connected to a first light source, the output of the second dimmer being connected to the first light source, to another light source or to no light source, the method being characterised by the following successive steps: operating the assembly of at least two dimmers (10, 20, 30), either in a mode of operation cut-off at an angle, or in a mode of operation of conduction at an angle, in a first step of recognising the wiring and in the mode of operation cut-off at an angle, from at least two consecutive cycles, opening the transistor of the first dimmer after opening the transistor of the second dimmer in the first cycle and opening the transistor of the second dimmer after opening the transistor of the first dimmer in the second cycle, in the first step of recognising the wiring and in the mode of operation of conduction at an angle, from a least two consecutive cycles, closing the transistor of the first dimmer after the closure of the transistor of the second dimmer in the first cycle and closing the transistor of the second dimmer after the closure of the transistor of the first dimmer in the second cycle, in the first step of recognising the wiring and in the mode of operation cut-off at an angle, for the second dimmer, measuring in the first cycle the voltage at its output by means of the voltmeter in order to determine a voltage drop to zero moment of the possible light source to which its output is connected, implementing in the following second cycle the closure of its transistor at the moment of the thus determined drop to zero and observing whether the moment of closure of the transistor of the second dimmer converges towards the moment of closure of the transistor of the first dimmer, in the first step of recognising the wiring and in the mode of operation of conduction at an angle for the second dimmer measuring in the first cycle the voltage at its output by means of the voltmeter in order to determine a moment of a jump in voltage of the possible light source to which its output is connected and implementing in the following second cycle the opening of its transistor at the moment of the jump in voltage determined in this way and observing whether the moment of opening of the transistor of the second dimmer converges towards the moment of closure of the transistor of the first dimmer. operating the assembly of at least two dimmers (10, 20, 30), either in a mode of operation cut-off at an angle, or in a mode of operation of conduction at an angle, in a first step of recognising the wiring and in the mode of operation cut-off at an angle, from at least two consecutive cycles, opening the transistor of the first dimmer after opening the transistor of the second dimmer in the first cycle and opening the transistor of the second dimmer after opening the transistor of the first dimmer in the second cycle, in the first step of recognising the wiring and in the mode of operation of conduction at an angle, from a least two consecutive cycles, closing the transistor of the first dimmer after the closure of the transistor of the second dimmer in the first cycle and closing the transistor of the second dimmer after the closure of the transistor of the first dimmer in the second cycle, in the first step of recognising the wiring and in the mode of operation cut-off at an angle, for the second dimmer, measuring in the first cycle the voltage at its output by means of the voltmeter in order to determine a voltage drop to zero moment of the possible light source to which its output is connected, implementing in the following second cycle the closure of its transistor at the moment of the thus determined drop to zero and observing whether the moment of closure of the transistor of the second dimmer converges towards the moment of closure of the transistor of the first dimmer, in the first step of recognising the wiring and in the mode of operation of conduction at an angle for the second dimmer measuring in the first cycle the voltage at its output by means of the voltmeter in order to determine a moment of a jump in voltage of the possible light source to which its output is connected and implementing in the following second cycle the opening of its transistor at the moment of the jump in voltage determined in this way and observing whether the moment of opening of the transistor of the second dimmer converges towards the moment of closure of the transistor of the first dimmer.
