<p>The invention relates to an electrical device comprising a wireless remote control (1) and a remotely controlled electrical apparatus (2), this apparatus itself comprising an electrical energy input (21), main units (3), a controlled contact circuit (4), and a control circuit (5) designed to deliver to the contact circuit, in response to a wakeup signal transmitted by the remote control (1), a change-of-state signal making it possible to wake up the electrical apparatus (2). According to the invention, the remote control (1) is designed to emit, as wake up signal, a collimated energy wave (10), and the control circuit (5) comprises an energy transducer (51) suitable for producing the change-of-state signal directly on the basis of the energy of the wakeup signal.</p> |
