DC Signal Trigger Remote Switches

These wireless switch kits include a DC voltage controlled transmitter and a receiver with a relay output or DC voltage output.
They are used to wirelessly control another DC or AC device via a DC voltage signal or a DC output signal from a device.
For example, if you want to control the device A by the 12V / 24V DC output signal of the device B:
First connect the device A to the receiver's output terminal, then connect the DC output terminal of device B to the input terminal of the transmitter.
When device B outputs an DC signal to the transmitter, the transmitter will emit a wireless signal "ON". When the receiver receives this wireless signal, it will activate its relay to turn on the device A.
When device B stops outputting an DC signal to the transmitter, the transmitter will emit a wireless signal "OFF". When the receiver receives this wireless signal, it will deactivate its relay to turn off the device A.
They can be used for synchronous wireless control of various home, industrial or agricultural equipments, such as wireless control of the warning host and the warning horn, wireless control of the lights, wireless synchronization control of the equipments and so on.
