Smart Home 433Mhz DC 12V 1CH Wireless Remote Switch

I bought this switch in my woodworking shop to remotely control the dust collector. It runs at 220 volts and 15 amps. I encountered installation difficulties at first, and the customer service handled it very well. The service included me sending them a video so they could confirm that what I did was correct, and then sending a replacement switch. When Maggie was with me, I installed the switch over the phone via WeChat in China. When the switch was also defective, Maggie sent me a replacement part and a spare part directly from the Chinese factory. Then the installation is very simple and the switch works immediately

I should have done this long ago. I have a container trailer. It has a wired remote control for hydraulics and another wired remote control for winches. I had to be two feet away from the fifth wheel and a bed to lift me up. I can't see what's going on. Now I put my hands in my pockets and can load and unload as I walk. Speed ​​up the process by a factor of two or more

I bought two about two months ago. My friend’s barber shop installed one as a temporary solution, replacing the shopvac when the central vacuum device of his six barber chairs was being repaired. Since its installation, it has been used six days a week, opened and closed several times a day, without any problems. The remote control is also very easy to use. The receiver and the shopping vacuum cleaner are in adjacent rooms, and the signal passes through the wall to reach the other room without problems.

This product works very well. I bought it to control the tennis machine from the other side of the court. I was able to configure the buttons to enable the goal and oscillation motors. I haven't figured out what to do with the other two buttons, but it is a good idea to replace the original receiver that is missing from the remote control. The radio frequency signal can penetrate the plastic casing of the machine, so I can press the button from anywhere on the court. Thanks to the person who posted the wiring diagram and the company for assembling a reliable product.

I did this work on my hydraulic trailer, but it needed more than just the explanation in the instructions. I can't find any commenters to explain what to do when you need to support common ground in both directions. My hydraulic pump has two electric valves-one for up and one for down-but I also need to power the solenoid valve that controls the pump motor, and the power must be turned on in either direction. A relay of this remote control is connected to the ascending valve. A relay is connected to the down valve. I could run a third relay for the pump motor, but then I had to press two buttons to operate the trailer hydraulics. Solution: Connect the power supply of each valve to the pump solenoid valve through a diode. You must install a diode to prevent the power from either valve from being fed back to the other valve through the solenoid. Once the solution is implemented, it works well. It has not been used enough to get a good understanding of the distance between the remote control key and the relay to communicate reliably.
