DieseRC 433Mhz Universal Wireless Remote Control Switch DC 12V 1CH RF Relay Receiver Module with 2 Transmitters, EV1527 Learning Code Remote Switch

Works great, remote has decent range in a challenging environment.As a note, I found mine can operate down to about 9 volts. That may be helpful to somebody.Smaller than I thought, which is good.Instructions were clear enough.I'd buy it again.

I used this relay as a remote kill switch for a go kart for my kids. Works perfect. Easy to install. Easy to use.

How do you salvage a very old garage door opener that is still mechanically sound but the remote(s) are failing and no longer made? You get one of these remote control switches and you have a more modern solution at a minimal price!The good:Extremely easy to install.Works well.Can be configured to operate in multiple ways: momentary switch, toggle or latched. To work withe the garage door opener, momentary contact is the applicable mode.As ca be seen in the pictures, the receiver is extremely small. This facilitates its installation (anywhwre) but also requires careful handling when attaching the wires.Installation tips:You need an external 12 VDC power source. I used a discarded wall charger that I had from an unrelated product.My unit came pre-configured in latching mode, so I had to configure it to momentary contact operation. Just follow the instructions for configuring the modes in the attached booklet, don't try to reset or pair anything. Two clicks and you're done.I found that each remote had to be configured to operate in momentary mode separately, i.e. I first thought that a single mode configuration would have been sufficent; not so, I had to repeat it for the second remote.For some applications, the above may be a useful feature, as you can make the receiver operate differently depending on which remote one uses. Not my case as a garge door opener.The remotes feel well made and I ordered visor clips to put them in the cars.In summary, I am very pleased with the product. It solved my needs and added life to my ancient garge door opener!

This relay works GREAT!I wired up a couple 12V outdoor lights to illuminate a corner of my yard, powered by my generator battery. I included a dusk-to-dawn switch but also wanted additional control so it's not drawing power off the battery unnecessarily. This remote switch filled the bill!

I used this to replace the barely functioning, extremely frustrating radio receiver on a 2014-built Chamberlain garage door opener. I had tried buying new transmitters, but they made no difference. By wiring the relay contacts of this little device across the push-button switch terminals on the Chamberlain unit, locating the new device on the garage wall above the roll-up door, and programming it for momentary operation, the garage door remote control operation is now good as new and very satisfying.

Works well and the price is right. Instructions are... adequate... at least for a hobbyist... But I wouldn't describe the item as plug and play.

The media could not be loaded. The range was about 300ft in the video. Very easy to install as a kill switch in my carbureted motorcycle as a ground kill for the cdi. Remote is good. Very small and fits in as a real component on the bike. Would recommend. Also the bike is very quiet in the video but if you listen closely you can hear it kill when I press the button.

The remote transmitter will activate ("ON") the NO just fine at 50 yards. BUT, the "OFF" button won't work >3 yards. Both remotes that shipped with the controller suffer this syndrome. I don't get it, I just don't get it... it's just digital bits in RF land, same power, same distance, different 1s and 0s. Unusable.
