Abstract: A remote control device for an installation of electrical toys on a circuit comprises a radio emitter (400) for emitting different radio-electric signals (b) selected by the user and a fixed radio receiver (450) for detecting and transmiting the radio-electric signals to an electronic device (270) which interprets the signals and triggers a control device (275). Specifically, the radio signal (b), which is emitted by the radio emitter, comprises a repetition of a word composed of a series of presences or absences of electric pulses. The word is formed according to an associated coded signal (a) and in accordance with the user's selection.
