- I use these cheap RF switches a lot for home automation, garden lights, lamps etc. so I thought I would make a quick how to video. They can be purchased from banggood here:

I bought one of the same little RF Switch as you describe here. Your YT video was a great time-saving, because no instructions for the wiring came with the device. One little thing that I did not like about the RF Switch. It has no LED Indicator Lights on the black plastic box. I wanted to be able to 'view' this black box, to know if the Unit is ON or OFF. My use for this item is to transmit 20kHz sound waves.
So I went and bought two (2) blue flashing LEDs, then drilled two holes 5mm dia. I wired the LEDs to the NO Terminals, via a 470 ohm series resistor for each LED.
Now, everything works, and I can see in an instant if the RF Relay is ON. Thanks for a very useful video. Greetings from Australia.
Good job Peter! And thanks for your message, I'm pleased you found one of my videos useful
Thank you so much. I was not sure about the wiring and I thought I need extra power to run the relay. But after watching your video, I have known that its so easy. Thank you from Bangladesh.
Thank you very much for this. Got my 12v solar lighting working spot on. Really appreciate you posting the video. 👍😄
Hi Sat, thanks for your message, glad it was of some use!
Way to fast for me
Well shown visually, and explained very well... Too ...
Thanks...

Thank you so much! This is what I was looking for!
Thanks heaps man awesome I was just connecting battery + to + and - to - then putting a light on the other end trying everything
Bhai tune last moment pe Jann bachaiyeer thanks bhaii ❤
Thank you very much, you made a very good help to me. It's easy to understand.
Thanks for your comments, glad you found it useful
I used this for rebooting my WIFI router from the other room without having to go there to unplug the whole thing. Very useful device.
You dont need this to reboot your wifi router, you can do it from your phone
Thanks for the feedback, glad it was of use
Finaly. You saved me. Thank you
Great video, love a wiring diagram. Heres my question though, are the modules encoded with their own keys, or are they just listening for ANY signal on the 433 MHz channel?
Thank you so much, saved my day.
Glad it helped! Thanks for the feedback
Thanks.. Can I use this as a 12v door alarm ?
Very helpful, thank you!
Great explanation would this work for a diesel heater 12v
Thanks man Saved me from smashing that thing
haha thanks for the feedback, glad it was of use!
How do I modify a 12V 433MHz wireless remote control switch relay receiver and transmitter? Someone in the area (neighbor) is using the same frequency.
Could you use this as a kill switch for a car fuel pump if you cut into one of the fuel pump wires? Great video
Don't see why not, just change the wiring accordingly
i have n 220v i connect this in the same way?
Tanya gan......
Itu bekerja di frekwensi radio 433Mhz ya.....
Lha seandainya transmiter / remot di gantikan pake radio ht uhf dengan frekwensi yang sama 433Mhz apakah bisa...?
can you run a 24v motor with this from a 12v battery? thanks
Thanks,sorted things out now+++++++++
Great!
If this fails? Can the connected thing be onn ?
Thx,. I'm putting an car alarm to my truck. This will work great. One question,. Do they offer a second remote?
Do they really need 10A?? Or is that just the relay rating?
I'm not terribly good with electronics but I need something like this for a project that will run off a 12v 3000ma battery pack.
Any info you could provided would be greatly appreciated.
Hi there, 10A is just the maximum rating. Your 3mAh battery will be fine, just not sure how long it will last!
@@cabuu4122 excellent - thank you.
I already have a heat temperature sensor circuit from Maplin (they've gone bust here now) which runs off 3 Samsung phone batteries. Takes about 4-5 days to drop from 12.6v to 10.9v if it is constantly on so this shouldn't differ too much I hope.
Really appreciate your prompt reply.
Can you give me some advice on fitting the same sort of thing I've got and fitting it to my 12v golf trolley
Hi Dave, happy to help if I can, what sort of advice do you need? How far have you got?
@@cabuu4122 have you got an email address so I can send info and a few pics . I've not started to attempt it yet
@@cabuu4122 my email address is hackettdavid@hotmail.com
Just trying to add a 12v remote receiver to my golf trolley if you can help
hey, i used a 18 volt battery and a 12 volt led . can i know why the led doesnt turned on ? what should i change to make it work. is 12v the maximum input?
Hi there, I believe you can switch higher voltages but the operating voltage (i.e. the one provided on the input side) must be 12V. Check the specs on banggood for more information: www.banggood.com/custlink/GDKKSZ4sG8
Thanks, I do have a prob, whatever button I push my load comes on and won’t go off no matter what program I’m using. Any ideas?
Sorry not sure about that one, did you manage to resolve?
I have the 12v R121A with 2 remotes having only 1 button on each remote. it came with2 remotes. Does each one have to be paired simultaneously? One was was shipped paired, but was its working in the latch mode. I need to wire it for a momentary contact like a door bell button. They call it jog or bump mode. I cant get it to work. Already got 10 hours into it. Help!
Not sure, I've only ever received one paired remote, I seem to recall there was instructions provided about pairing remotes so maybe try there, good luck!
so the jumper cable source (+) to NO, and source (-) to load (L1) , load (L2) to common ?
That is what it looks to be.
Hii I hve an electric skteboard which has a 12v led on off switch currently.
I want to replace that switch with this remote. Will it work? how to connect?
Should work no problem, just follow the schematic for using a 12v device
You my friend deserve a round of applause. Your drawing could use some work though :)
Haha never my strong point! Thanks for your comments
NICE VIDEO, PLEASE EXPLAIN AGAIN HOW I CAN USED LESS THAN 12VT . I REMOVE WHAT WIRE WHERE ???
You still need 12v to power the switch but you can then switch more or less than 12v by doing away with the red jumper cable (going from left to right) and inputing your switch voltage on the right hand side where the 12v jumper did go, hope this helps
THANK YOU , SO I CAN USE A 9V BATTERY BY ELIMINATING THE JUMPER WIRE ,,,,, CORRECT ?
@@mw10259 You'll need to remove the jumper cable from the left hand side (the 12V side) and connect to your 9V source, hope this helps!
Can somthing be done to the antenna for further reach ?
You could try adding your own longer length coil of wire, that should improve things.
Any one know the amp draw of this little unit?
Hello, I am trying to use one of these remote controls to trigger a 50amp relay, to run power to an air compressor. I am struggling to figure which way I should wire it. Do you have an email address I maybe able to contact you at?? I can’t post a picture on here otherwise I would show you what I am trying to do.
Feel free to email info@cabuu.com I may be able to help
Is there a way to transmit a 433mhz signal when 12v is supplied? Is there a device that will do this? I don't want to have to push a button to operate the switch. I want the switch to close and then send 433mhz signal. Can you help?
Certainly, but you'll need an RF transmitter and it'll take some coding to ensure the correct signal is sent. I've used something like this before with some success... uk.banggood.com/Geekcreit-433Mhz-RF-Decoder-Transmitter-With-Receiver-Module-Kit-For-ARM-MCU-Wireless-Geekcreit-for-Arduino-products-that-work-with-official-Arduino-boards-p-74102.html?cur_warehouse=CN&rmmds=search
@@cabuu4122 is there a way to take the handheld fob and mod it to be a dedicate transmitter. Maybe a way to simulate the key button press on the fob with a relay that trips when it detects the 12v signal? I'm really interested in learning more and I'll definitely look at that link. Thank you btw!
So I already have a 433mhz transmitter and receiver that can control a motor via a fob for forward, reverse and stop. I was just thinking maybe I could modify the fob so I don't have to press the buttons some how?
I know very little almost nothing about adrino board. I know what they are and kinda how they work but if I can work around having to use it. That would be ideal because I have nothing you need to program or test or etc on adrino. What kinda coding are we talking? I've only done very little with coding. Mostly just modify existing code with code someone else generously provided. I'm willing to certainly learn. That's not the issue. But if there's a way to do it with what I already have. That would be the way I'd like to go if I could.
But I do have electronic knowledge and have programmed ic in college using breadboards and such but that's been 20+ years ago lol. My thinking these days is do it the easiest way with what I already have. I just feel that since the TX and Receiver are already "talking" to each other. Maybe it would be easier to just use the 12v signal to trip relays to simulate button presses from the fob. And I can get extra fob if I mess it up, really cheap.
How do I program it to Switch on by pressing any one switch and Switch off by releasing it?
I'm not sure this is possible with this module at least I haven't tried to do this
My receiver has + - NO Common and NC all in a row. How do I wire it up?
Connect - with load too and + from source to common and NO or NC to load
Thanks for helping with this one Salman
Can you use this as a kill switch for ignition?
I guess so in theory but it's not something I've tried, check the specs on the banggood website in the link in the description that might help answer your question
You could use it to turn off the fuel pump
Sir how to wire in to motor of power window that we'll be go up and down sir
Depends on your motor, if it's just power it needs that it should be simple enough to follow this guide alone
Can these be coded for security?
Not sure, I think they're pretty un-secure!
Can this be used in a car for remote control lights?
Don't see why not, the 12v supply from a car battery would work fine, not sure how much it would drain the battery by though would have to see how you get on
I'm still confused. :D
That's a disappointinly poor explanation of how to wire this thing up. I'm even more confused than I was before.
