fushionseaDC 5V 6V 9V 12V Wireless Control Switch 433mhz Remote Relay Latching Switch, 12V Long Range Remote Transmitter and Receiver for Indoor and Outdoor Use

I have never messed with anything like this. Checked out some YouTube videos and I bought one. I wired it up pretty quick and just twisted the wires together. Well when I soldered everything up yea I wasn’t paying attention and it stopped working. My bad I’m buying another and going to do it right this time.

These relays were perfect for an application I needed to create. I have an additional (BIG) battery in the back of my vehicle to run some amateur radio equipment. I wanted a way to disconnect both that battery and the vehicle battery from which it charges and is isolated. I used these relays as pilot relays for much larger 40 A automotive relays that disconnect each battery from its load. It allowed me full control of my setup without wires. They consume extremely little current to run their receivers (which are always connected to the batteries - with fuses). Other ignition-off loads in the vehicle will discharge the batteries much sooner than these will. The only issue I saw was that the leads are very small wires and quite short. I had to use considerable care in making connections with them.

it uses 28g wire which is next to impossible to link to other wire. It only handles a FRACTION of an amp of power so it is totally useless even when I paired it with a low-volt RELAY-SWITCH. I cannot imagine any electronics that this little thing could even control.

The remote worked great. I have a gas fireplace and the remote quit working. I looked on-line for a replacement and all were over $100. When testing I found the remote only required a contact closure so I purchased the “latch” remote and wired a 9v alkaline .battery for power. Works great!!!! Red-+9v, black-negative, yellow and white connected to the fireplace controls.Update: the 9volt battery only lasted for a few days. Ended up using a 9 volt power supply that I plugged in to the outlet for the blower motor. I should be all set now.

I've installed two of these so that you do not need to go to the generator to shut it down while camping. I powered it with a usb adapter plugged into the generator because when I tried a 9 volt battery, it emptied the battery in 3 days if I did not disconnect it in the morning( and I did not want the hassles of having to remove the battery every day). Very easy to wire and they do not interfere with each other, so multiples can be used near each other without problems. I used a Cable Matters usb hub power brick to power it and it has enough residual power to latch the ground to the coil for shutdown without problems. Great item.
