DC 12V 40A Relay, 1CH Universal 433Mhz Remote Control Wireless Latching Function Switch for Industrial & Low Voltage Power Systems

So far it works like a charm. The battery on my generator won't hold a charge so I use this to temporarily supply power to it from the batteries that the generator charges when it's running.

This is by far the easiest way to hook a light bar or any external lighting to your vehicle. As you are not drilling into the cab. You're not looking for holes to run wires through you. Just plug and play and then use a remote This is actually my second one of these. I even had one hooking up an amp to a factory deck because I didn't have access to a remote turn on and the remote turn-on setup that I found did not work with what I needed to do and with having the battery in the back of the vehicle it made it 10 times easier to use a remote to control everything and keep everything contained to the trunk. No wiring going anywhere

I had a switch that malfunctioned on my houseboat for a freshwater pump for a washdown hose, I decided to install this remote relay instead of having to flip a switch on every time I could actually carry the remote, I am very impressed as far as the distance that the remote works . I’m very simple hook up. Nice effective way to switch something, amp rating is very high.. quality of remotes seem very good!! I will buy again

I use this with my four-wheeler and my yard sprayer. It keeps me from having to run wires to the handlebars. So far it works good.

The media could not be loaded. Using this unit to control the trolling motor on my kayak (Endura C2 30lb thrust). I have yet to do a prolonged test out in the water, but my initial tests looks good. The unit worked out of the box and it was easy to install. The remote control isn't waterproof, so I'll have to bag them incase I go for an unscheduled swim.EDIT: 06/28/2021 - Ran my motor at full throttle for about 3 hours (due to high winds and 3' waves). It did not survive. I think I asked too much from this product so I'm not blaming it for it failing. However, if anybody is looking to use this to control a trolling motor, now you have an idea of its limitations.

Hooked up just like it said it would has been working fine, can do a momentary, one switch on one switch off or one switch to do on and off

We have a Jeep Cherokee which has a recall for the power liftgate fire hazard (even when the car is not running) due to corrosion on the electrical contacts. Jeep, as yet, has no remedy for this problem and simply did a CYA by recommending owners not park the car in their garage or near any buildings. Very practical...Pulling the fuse avoids the problem, but then you can't use the rear liftgate and have to load and unload the trunk from the passenger compartment by folding the rear seats.I connected this receiver to the fuse box and set the mode to only supply power to the liftgate circuit while the remote button is being held, so you can't possibly leave the circuit powered unintentionally or for an extended period of time. Works great and my Wife loves it (at least compared to parking the car a block away).

Almost sent back because I could not get it to work. Instructions mentioned "learn button" but drawing in instructions did not show one. Contacted supplier and they sent new instructions and drawing. Works great now. Instructions below.Clearing method: After applying 12 volts, hold down the learning button. Keep holding until the receiver Led indicator flashs for 5 times. It will flash once, then twice, then three times all the way to five. It is Clearing Code.Learning method : Apply 12 volts to the Receiver , Press and release the learning button. The receiver Led indicator will come ON and stay on. Now press remote button “ON” 1 time, Led indicator flash for 1 times , Then Press remote button “OFF” 1 time , Led indicator flash for 1 time again , it mean learning successful.Oh, for those that had a question on operating temp of 80? That is in degrees C. That's pretty darn hot!
