FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to switching devices. Switching device comprises: a receiving converting component configured to receive a wireless signal and convert the received wireless signal to a power supply signal; a first power component connected to the receiving converting component and configured to accumulate electric power based on the power supply signal; a control component connected to the first power supply component and configured to enter the operating state based on electric power supplied by the first power supply component and to generate in the operating state a control signal; and a first switching component connected to the control component and configured to switch to the on state or the off state in accordance with the control signal.
EFFECT: technical result consists in providing more convenient and fast power supply to switching device based on electric energy converted from wireless signal, without influence of ambient lighting and power of controlled device.
