This wireless switch or radio receiver is an electric device with 1channel dry relay output (Normally open and normally closed), it and the transmitter form a receiver transmitter system. This kit may be used in all types of industry automation, agriculture, home, factory, house, farm, vehicle, ship, offshore operations, aerial vehicle, etc. It can remote control equipment on land, water and air, such as remote control of lights, sirens, locks, motors, pumps, fans, winches, blinds, linear actuators, doors, windows, electric solenoid valves, security alarm, and business signs. The applications are endless.
Wireless control, easy to install.
Waterproof: The receiver has waterproof case and waterproof connector, it can be installed outdoors.
Universal input: Support 110V AC (100V~120V) used in US, Canada, etc, and 220V AC (200V~240V) used in Germany, UK, France, etc.
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.
When you set the receiver in Self-locking mode or Momentary mode, it should work with single button transmitter, such as model C-1 (100 Meter / 300 feet range), CP-1 (500 Meter / 1500 feet range), or CB-1 (1000 Meter / 3000 feet range).
When you set the receiver in Interlocking mode, it should work with two buttons transmitter, 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-1 or 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-1): Press -> On; Press again -> Off.
Press the button on the transmitter: The relay in the receiver is activated, and the connected lamp is turned on.
Press the button again: The relay is deactivated, and the connected lamp is turned off.
2) Setting Momentary mode: Press and hold the button of receiver until signal LED flashes 2 times, then release button.
Control mode Momentary (working with transmitter C-1): Press and hold -> On; Release -> Off.
Press and hold the button on the transmitter: The relay in the receiver is activated, and the connected lamp is turned on.
Release the button: The relay is deactivated, and the connected lamp is turned off.
3) 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 in the receiver is activated, and the connected lamp is turned on.
Press the button B on the transmitter: The relay is deactivated, and the connected lamp is turned off.
