EKYLIN 12V Remote Control Car Battery Switch Wireless Disconnect Latching Relay Anti-theft Electromagnetic Solenoid Valve Terminal Master Kill System for Car Solar System Vehicle Water Pump Auto Gate

It's not what described, product only comes with a manual on-off switch, not wireless switch, waist of time, please don't buy this.

I am very impressed with this switch so far. It's a very clever and (at least by appearances) well-made solution to battery drain problems. We purchased this for a plow truck that is used sporadically and has had a long history of the battery going dead on us. It's a wiring nightmare due to all the extra plow and light wiring that's been spliced in, and we have been unable to track down the source of the drain. Although a simple manual battery disconnect switch would have done the trick, we have a remote starter that allows us to start and warm up the truck before plowing, and a manual switch would have meant trudging out in the snow, clearing off the hood, and throwing the switch in the engine compartment before each use. With this switch, we can simply hit a button to connect the battery, and then hit a button to start the truck. All from inside the house. MUCH nicer. My one concern with going this route was having the switch fail in the disconnected position, leaving the truck disabled. An annoying inconvenience if I'm home with tools and able to bypass the switch with a few minutes' work, but a real problem if I'm out of town and trying to talk my wife through the process over the phone. Accordingly, I purchased an inline knife-type disconnect switch and a couple short lengths of battery cable and lugs and wired it to both sides of the electric switch as a bypass. If the switch ever fails in the disconnected position, we simply flip the knife-switch closed to bypass the electric switch and reconnect the battery, and open it to disconnect again. The switch comes with clear wiring instructions and is easy to set up. However, some will find it challenging to find suitable mounting locations, and the wiring can be a bit of a rat's nest. I elected to mount the switch, receiver, and bypass switch to a small piece of board. This not only gave me a convenient mounting surface close to the battery, but also keeps the wiring shorter and a bit more manageable. (See photo.) One note for those ordering extra remotes (available separately on Amazon): You will need to open the white plastic receiver box and access the pairing button inside to pair the additional remotes. The description on the remotes page lists the steps to pair them, but it fails to tell you that if you hold the pairing button for more than 5 seconds, you can switch from two button operation (lock button disconnects and unlock button reconnects) to single button operation (battery is disconnected unless you're holding the unlock button down-- in other words the switch won't latch in the connected position.) I inadvertently got into this mode when trying to pair my extra remotes, and thought the switch had failed. When I contacted the seller to replace the switch, he told me what the issue was and how to change it back. It would be nice if they sent out full programming information with the switch, or at least with the extra remotes. The red LED pairing light is hard to see in full daylight, and it's easy to accidentally change modes if you hold the pairing button down too long. Overall, great product so far. As a previous reviewer noted, this is a latching relay, so it isn't using power to hold the switch open when the battery is disconnected, which is very important. It uses only a tiny amount of power to keep the receiver powered up. Will come back and change the review if the switch doesn't hold up over time, but so far I'm pleased with it, and the seller was prompt and courteous in helping me sort out the problem with the programming.

I bought this product as it showed in the photo a remote control unit to operate the switch but when I opened the box there was only a manual switch

I got it to solve a draining battery problem on a friend's Acura, that his mechanic had been unable to troubleshoot. I proposed an under the hood knifeswitch or twist switch, but that was deemed not acceptable. Car is not driven regularly, so the battery would go flat, and the car would need a jumpstart. and killed battteries. A very inconvenient situation, to say the least. If this does not turn out to have completely solved the problem, I will dispense with the wireless trigger (and its "always on" receiver that draws something like 0.008 amps) and simply add a toggle switch to energize the relay. I did not disassemble the high current relay but it feels very very solid. I got 2 remote keyfobs and the second one paired with the receiver without issues. These remotes have a sliding cover that seems like a good idea, to keep it from triggereing accidentally. As the image shows, I mounted it securely to the chassis using one of the car's McPhereson strut mounting bolts, and I wired it to break the ground rather than the positive battery connection, to minimize the number of heavy gauge wires that I had to add. It is not a perfect solution: the radio's clock will lose tyrack of time while the battery is disconnected, but that is minor compared to killing batteries and being unable to start. It took me longer to go the the autoparts store and get replacement battery than it took to install the relay.

It works exactly like it should, and setup was pretty easy if you have experience with a drill. I put this in a 1997 Chevy k1500. The solenoid is very large, I had trouble finding a good place in the engine bay to install it. It’s intended to disconnect the battery but I was worried that it would reset my radio each time, so I modified it to disconnect the starter. Now I turn the key and the radio and fans will turn on, but the truck won’t start until I turn off the solenoid. I like that it’s not a button or switch that I had to place in the cab, the remote replaces the need for a switch or button.
