The invention discloses a wireless intelligent single-firing-wire switch applied to a single-firing-wire circuit. The wireless intelligent single-firing-wire switch comprises a power switch, an on-state power supply circuit, a charge management circuit, an energy storage element, a wireless control circuit and an off-state power supply circuit, wherein the input end of the power switch is electrically connected with a controlled load, the input end of the on-state power supply circuit is electrically connected with the output end of the power switch, electric energy is obtained by utilizing working current of the load, the input end of the charge management circuit is electrically connected with the output end of the on-state power supply circuit, the energy storage element is electrically connected with the charge management circuit to perform electric energy storage, the wireless control circuit is electrically connected with the charge management circuit and the power switch and outputs an instruction signal for correspondingly controlling the power switch to be turned on/off, the input end of the off-state power supply circuit is electrically connected with the controlled load, the output end of the off-state power supply circuit is electrically connected with the wireless control circuit, and the off-state power supply circuit outputs low-voltage current to the wireless control circuit. The problem that certain current still exists in a loop and the flare phenomenon of a controlled illuminating lamp exists when a wireless intelligent single-firing-wire switch in the prior art is in an off state.
