摘要： A control system for a wireless power switch without a NEUTRAL wire comprises a wireless controlled power switch with both terminals connected between a LINE wire and a switch wire of a switch box without the NEUTRAL wire; a power acquiring device having two power input terminals respectively connected to the LINE wire and the switch wire of the switch box; and a wireless automation control device receiving an output voltage of the power acquiring device as the required power, the wireless automation control device controlling open or close of the wireless controlled power switch according to wireless control signal wirelessly. Specifically, a load device is connected between the switch wire and the NEUTRAL wire, and impedance between the two power input terminals of the power acquiring device is substantially larger than impedance of the load device.

摘要： A radio-frequency (RF) controlled switch box without using Neutral wire includes a relay, and an RF controlled circuit that receives an RF control signal to control open or closed state of the relay. The RF controlled circuit, the relay and a light-emitting diode (LED) light bulb are connected in series between Line wire and the Neutral wire. The RF controlled circuit includes a voltage clamper. When the relay is closed, mains voltage between the Line wire and the Neutral wire is distributed between the voltage clamper and the LED light bulb, such that the voltage clamper generates a clamped voltage and the LED light bulb turns on. When the relay is open, the RF controlled circuit takes power from a rechargeable battery.
