Wireless Remote Switch 12V, DC 12V/24V/48V/72V/40A Relay.

Works as expected. I somehow feel I underpaid for this product. I paid so little for this product, I really expected it to not work. But it works very well, has good range. Controls the work lights on my trailer from inside the cab with no issues. If you need it for something similar, buy it. I was concerned about it getting wet, so far, no issues.

I installed a set of backup cameras on my boat that required 12 volt power and had to wire them under the deck. I needed an easy way to turn the power on and off. I installed this in the bottom of the boat in the back, I can easily turn them on and off now from the cab of the truck pulling the boat. Very nice and super easy. My recommendation is to figure out how you want to connect things and buy the connectors you need at the same time. This does not come with wire or connectors and you may need terminal connectors if going to the battery, and probably some 14 ga. Wire. It was easy once I had all the wire and connectors. The key fobs are pre-programmed, so once I got everything wired up, it just worked.

I used this switch for my engine cooling fans. Works great!

Works good for my old school garage door opener but it works as an on off switch so every time we clock on to open the door u have to click off other than that it works good

Works great on my electric jet ski project. Small, simple, remote, and good range. Will get another.

I bought one of these to turn on and off LEDs in my hood scoop and mounted in my scoop. It failed after a couple months. Since the scoop is on top of the engine it gets hot, I wrote to that. Got another and mounted to fender but it failed there as well.

My first one I ordered was a dud. Did not work but got another one right away and it worked perfect. Simple. Easy to use. Just hook it up to 12 volts and the other end to whatever you're trying to run. Multiple applications for this. I am using it to power up a water pump. Highly recommend especially for the price. I personally have not tested the distance of how far you can go before it doesn't work.

This is the 2nd one I've bought of this style by "dstfuy". I own 2 others that are the mini versions. I like this model for its robust construction, durability, and ease of use. It also has a "momentary on" setting that the others don't have. The settings I use are "on/off, toggle, and momentary". These relays have an unlimited number of uses. Just in the camping category you can pair it with a rechargeable power tool battery and remote power a camp light, a radio, or even a siren paired with a flood light if you're in a sketchy area. I often pair one with a Harbor Freight 24volt power tool battery and a Harbor Freight LED Flood light. Instant whole camp illumination from 200 feet up the trail. Awesome piece of electronics and that's a welcome change from the other Chinese junk the world's being filled with.
