This 2 channels AC 110V 220V wireless switch with remote control(transmitter) is memory function. If the power is cut off, the relay on the switch will return automatically to the previous status after the power is restored. It can long distance remote control DC and AC equipments, such as long range remote control light, lamp, locks, motor, pump, fans, doors, windows, electric solenoid valves, etc.
Wireless control, easy to install.
Waterproof: The receiver has waterproof case and waterproof connector, it can be installed outdoors.
Universal input: Support voltage of AC110V (100V~120V), widely used in US, Canada... and voltage of AC220V (200V~240V), used in UK, France...
Relay Output: This receiver is dry relay output, it can be used to operate both DC and AC equipment. The output terminals are NO / NC (normally open / normally closed), serving as a switch.
With external antenna, the receiver has a farther working range.
The transmitter / remote can control the receiver from any place within a reliable working distance.
The wireless RF signal from the transmitter can pass through walls, floors, doors or windows, but it will lose some operating range.
The receiver has reverse power protection and over current protection built in.
The receiver only works with the selected transmitter which is matched to the receiver.
One or more transmitters / remotes can control one or several receivers simultaneously.
Two or more receivers may be used in the same area.

The receiver can work with different transmitters. such as model C-2 (100 Meter / 300 feet range), CP-2 (500 Meter / 1500 feet range), or CB-2 (1000 Meter / 3000 feet range).
With a transmitter (such as C-2) to form a complete set, the maximum working distance can reach 100 Meter in an open ground.
The maximum working distance is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, it will be hindered by trees, walls or other constructions, and will be interfered by other wireless signals. Therefore, the actual distance may not reach this maximum working distance.
If you want to have a further working range, you can replace external antenna of the receiver or use a high-power transmitter, such as CB-2 transmitter.
Setting different control modes:
1) Setting Self-locking mode: Press and hold the button of receiver until signal LED flashes 3 times, then release button.
Control mode Self-locking (working with transmitter C-2): Press -> On; Press again -> Off.
Press the button A on the transmitter: The relay 1 in the receiver is activated, and the connected lamp 1 is turned on.
Press the button A again: The relay 1 is deactivated, and the connected lamp 1 is turned off.
Press the button B on the transmitter: The relay 2 in the receiver is activated, and the connected lamp 2 is turned on.
Press the button B again: The relay 2 is deactivated, and the connected lamp 2 is turned off.
2) Setting Interlocking mode: Press and hold the button of receiver until signal LED flashes 1 time, then release button.
Control mode Interlocking (working with transmitter C-2): Press -> On, Press another button -> Off.
Press the button A on the transmitter: The relay 1 in the receiver is activated, and the connected lamp 1 is turned on; The relay 2 is deactivated, and the connected lamp 2 is turned off.
Press the button B on the transmitter: The relay 2 in the receiver is activated, and the connected lamp 2 is turned on; The relay 1 is deactivated, and the connected lamp 1 is turned off.
Function of memory:
When the relay is on the status of "ON", it will shift to the status of "OFF" when the power is cut off.
Once the power is restored, the relay will return automatically to the previous status of "ON".
