 To solve the problem, in a known device containing a remote control emitting an encoded signal, an input device receiving this signal, a decoder, the signal input of the decoder is connected to the output of the input device, and the output is connected to the input of the switching keys, the power supply of the electrical apparatus is connected via the keys to the mains , a decoder switch is introduced, a signal input of a switch is connected to an input device, and a background radiation energy converter, a converter output is connected to a switch power input, a power input is a decoder and through the key is connected to the power supply network.

Possible embodiments of the device:
- the converter is made in the form of a photodetector;
- the converter is made in the form of a radio receiver.

 When the decoder is powered by the energy of background radiation, the problem is solved and the above technical result is achieved.

 Figure 2 - functional diagram of the switch decoder.

 The device comprises a remote control 1 emitting an encoded signal, an input device 2 receiving this signal, a decoder switch 5, a signal input of a switch connected to an output of an input device, a decoder 4, a signal input of a decoder connected to an output of an input device, and a power input through a power switch network, the decoder output is connected to the switching keys 6, the background radiation converter 5, the converter output is connected to the power input of the decoder switch, the power input of the electrical apparatus 7 through the switching keys dinen with power supply.

 The remote control 1, input device 2, decoder 4 and converter 5 are known nodes / the latter is widely used to power calculators /.

 The operation of the device / Fig. 1/: remote control 1 emits a signal in the infrared, visible or radio range; input device 2 / in the case of infrared rays - receiving photodiode / receives it. The switch of the decoder 3 separates the signal from interference by the oscillating circuit 3-1 (Fig. 2/) / in the RC-5 code format, the signal pulses have a frequency of 36 KHz /, amplifies the amplifier 3-2; this signal unlocks the thyristor VS1 and through the stabilizer 3-3 the voltage of the supply network is supplied to the power input of the decoder 4. The signal is supplied from the input device to the signal input of the decoder. The Converter 5 converts the energy of the background artificial or daylight into electricity to power the amplifier 3-2. After turning on the decoder, its power is self-locking until a turn-off signal arrives, which consists of reverse polarity pulses. Having recognized the power-on signal, the decoder unlocks the switching keys 6 and turns on the device 7. When the power-off signal is received, the device turns off. If periods of the device being outside the background radiation are possible, then to maintain controllability, a capacitor of sufficient capacity or a battery must be connected to the converter with a buffer.

 The device can be introduced as part of a multifunctional remote control system when the device is powered by both alternating and direct current.
