433MHZ Wireless Remote Control Relay Switch 12V Waterproof Transmitter Momentary Switch RF Relay (1 Transmitter & 1 Receiver) DC3.7V 4.5V 5V 6V 7.4V 9V 12V

Well I bought this as a trial, soldered it into the case of a fairly powerful tazer the. Ran wire leads in the cushion of the office chair and had some really good entertainment! It's been dropped multiple times and still working like a charm!

Small remote is twice the size of the very small receiver. Attach 3.5-12v (transformer or battery) to red and black to give it the power to work. Clicking the remote will make a connection between the other two wires and can handle anything upto 24v. I bought it because I have ancient garage doors with only a wall-push button open/close. Now I still open/close with the wall button or use the remote from my car. Works like a charm. Somebody wrote you must solder; you could but I only used screw type wire connectors: no soldering needed.

The media could not be loaded.  So as a complete amateur with a vague semblance of electronics from 10 years ago, this product is fantastic - if it had clear directions. But it works at the end, I just had to wind up getting out a multimeter to see what was going on with the blue and yellow wires. I added a slight update to the first wiring diagram. For the amatuer, ignore the second or third diagram. They lead to a lot of frustration and made the project over complicated.In the end, momentary mode works great for the application. And if you want latching mode, just buy a different transmitter. They have one here, just with a different remote.This could be done cheaper and could be done simpler as mentioned elsewhere, and that's where the pros come in. They don't need the directions. So as it stands the product doesn't satisfy either intended consumer, but that could be changed with better documentation.Anyways, I got it to work, and the result is actually really cool. So keep at it.

I used this on my MM360 Mighty Mule automatic Gate opener, i should work on all models as long as it has power +/- and can temporarily short the common / cycle pins. Refer to the attached picture for wiring. I mounted it inside the MM360 housing. I insulated the receiver with 1" heat shrink just to make sure nothing could short out. I also installed a Sonoff relay board so I can use eWeLink to open the gate with my Phone.

Used it to convert an automatic cat feeder into a remote dog treat dispenser. Just wired it up and it worked first time. No issues.

It works but you may need to solder to change the operating mode, which is annoying. Soldering is anyway necessary to connect the wires, but to change the mode, you need to remove a chip resistor and solder for other place. It wasn't difficult for me since I am an engineer, but it could be designed better. And I think it is bit pricy.

I got the unit on time. It worked great and was easy to wire up. At 50 meters, it was still working reliably. I set it up so that the unit activated an LED which I could see through a window and I was outside and down the street three houses away.
