Device for controlling a lighting device

A device for controlling a lighting device (50), comprising a control circuit (110) having an input (102) for coupling to a mains voltage conductor (30) having an output (104) for coupling to a supply voltage conductor (40) of the lighting device (50). The control circuit (110) is designed to supply the illumination device (50) via the output (104) a supply voltage and control signals modulated on the supply voltage. The generation of the control signals can be influenced by means (120). The control circuit (110) produces an internal supply voltage (Vint) from a voltage, which falls between the input (102) and the output (104) of the control circuit. In a non-actuated state, the button (120) bridges the input (102) and the output (104) of the control circuit (110), wherein the button (120) contains a configuration module (191).
