I saw a motorized tent trailer winch using two relays to reverse polarity. This is how it’s wired - Авто та транспорт
If you can’t wire a relay without the numbers check out my other videos to learn how they work

Just wanted to say thanks. This is the 12th video I've clicked on. And watched it twice. And was able to wire up my actuators. Appreciate it the knowledge
Same here, Needed a reverse polarity relay for a camper top motor. This did the trick!
thank you, I have a momentary rotary switch thats two independent NO switches underneath. I had expected it be similar to a rocker switch but it doesn't work that way. Seems like I can use two relays to reverse a DC motor with this method. appreciate the video
Great! Thank you for posting.
Awesome walkthrough. I was looking for a reversing polarity switch diagram - and your UA-cam video came up on Google result page: only thing that would've made it better is an actual drawn out wiring diagram/pin out... As I had to zoom in to see your pins. But overall, sweet job 👍
thanks! worked great
Thank you! For this video.
Your welcome
Thanks very good
I love this that you had the wires already organized(with the terminal pins) before connecting them to the relay - makes it visually so much clearer to see the simplicity of how it is really connected - question - what if you want to add a diode here? would it be correct to have one for each relay? - Many Thanks for your response !
Not sure where you want to put a diode…
@@mikmaster63 in parallel to the relay coil - I assume I would need two diodes, one for each relay, yes?
a schottky diode not an LED
I didn’t use diodes and it works fine so I’m not sure why you need diodes. Here a link to the diagram video I made.

@@mikmaster63 I am using this circuit layout with sensitive equipment and want to use tamping diodes as a means to protect against back EMF when the relay coil go from energized to off. I think I will have to use two, one for each relay as they energize separately.........Thanks for your input much appreciated !!
Hi Mik Master
I am working on wiring in a motor into my car in the exact same way you have. The motor controls a small valve which opens and closes my exhaust. I purchased a genuine switch that fits in my car perfectly. It is a momentary switch which rocks upwards and downwards and then returns to centre. However it only has 2 connectors and not three connectors how you have demonstrated.
Is there any way at all to make this work? (I apologise if this is a silly question, I am a novice when it comes to these things. Just doing projects to learn).
Thanks
I never assume how a switch works. Most of them work how I expect but I always check them with a meter. Do you know the actual details of the switch? In this video you need to be able to apply power to one of the relays at a time. I’m not sure off the top of my head how you could do it with only one output signal from a switch…
@@mikmaster63 I'd love to tell you about my issue in more detail, with images included. Is there anyway that I could reach out to you? through and email or social media profile perhaps?
@mikmaster63 I'd love to tell you more about my issue in more detail, with images included. Is there anyway that I could reach out to you? Through email or social media perhaps?
@@mikmaster63 is there any way that I can contact you privately to discuss this further? maybe a social media or email address? I'd love to get your further opinions in more detail in relation to my project
Good Sir I want this connection Thanks
I wish you showed a wiring diagram for this.
Is that a DPDT switch in white? What is its rating in amps and voltage?
What relays are you using?
What is the voltage and amps of the winch?
I have 130 VDC 25 amp treadmill motor that I’d like to control with a rotating selector switch but it’s not rated for the volts or amps. Could this be possible using relays?
Thanks,
Paul

I work with mostly 12 volt in my line of work. Reversing direction of a AC motor is difficult from what I understand. The stuff I’m using is 12 volt 30 amp rated. You would have to use relays with contacts that are rated for your load (130 volts 25 amps) the coil could be triggered by lower voltage, just depends on the relay…
What kind of motor is it?
What is its voltage and amperage rating?
If it’s a DC motor, why not use a DPDT switch?
All this information is missing from your video.
I have a 4.25 hp, 130 VDC treadmill motor and I want push buttons for forward, stop and reverse. A normal DPDT toggle switch won’t cut it.
So I watched your video to see how it’s done with relays, but I still don’t know what to do.

It’s a 12 volt motor out of a RV Slideout. It’s 12 volt, the relays are rated at 30 amps. This is the video for for DPDT switch. ua-cam.com/video/_TotMbbH1ms/v-deo.html This info was not important for me to put in the video. It’s a video on how to wire 2 relays to reverse polarity. You would need to find relays that will handle whatever load you are trying use. How many amps does that motor draw. Is it really a 130 volt DC motor not AC? I think it might be difficult to find relays that size, at least I couldn’t find any. I work on primarily RVs so that motor you are trying to use is out of my scope of focus.
Try this guys videos ua-cam.com/video/B1pj3N1J2vg/v-deo.html
It’s a pity that you never put the numbers you connected the wires to Im trying to totally rewire a set of car seats with 3 motors in each chair any help will be great my switch have have 5 terminals on them

Bu peut'on mettre un programmateur a la place de l'interrupteur merci
Oui tu peut mais tu doit utiliser le module bouble relais pour arduino
Great thank 👍
Thanks for this I think I can use it.
I also would like to be able to adjust the speeds of forward and reverse independently. Any chance you have any idea?
Potentiometer
Cytron 10A DC 7-30V Potentiometer and Switch Control Motor Driver Speed Controller. Something like this maybe…
@@mikmaster63 that’s exactly what I was thinking and is exactly what I bought but you can only control one direction at a time. I’m wanting to auto feed a sawmill slow going into the log and returning at a quicker pace without any adjustments. I’m thinking it may not be possible without a PLC or an Audreno. Thanks for the response it’s much appreciated!
I’ve been thinking a lot about it. Is it AC or DC motor what’s the amp draw?
@@mikmaster63 12vdc I haven’t bought the motor yet until I have everything figured out. I’m looking at wheelchair motors and from what I’ve read they can draw up to 40 amps if working hard.
hi there! is that mean the heavy load does not pass through the switch, but only through the relays?
Yes
@@mikmaster63 Thank you. I have this problem with my kayak's trolling motor that uses 6-pin rocker switch for doing reverse polarity on-off-on. The problem is that this switch is rated 30 amps, but eventually it fails (melts) every few months in the middle of the sea. the motor is "only" 12v DC 20A (max). No matter how many different switches brands I have tried, they all fail eventually. some on the handle, some melts from the inside, nothing lasts.
Also, there aren't many high AMPS 6 pin switches. they all range 20-30 amps and they all fail.
I think this solution will solve the problem.
Thank you!
It’s sounds to me that there is another issue. Most of the relays I use are rated at 30 amps also. Check what amp draw the motor is actually drawing. It could be loose connections or a bad motor. Also, try a marine type switch (something water proof) maybe the moisture is corroding the switch…
@@mikmaster63
When its 95 degrees Fahrenheit outside with intense usage of few hours twice a week, the plastic parts of those switches get distorted. It happens every 5 months in average. Tried some metal switches they also falied with some plastic pin inside. With a relay THERE IS NO PLASTIC INSIDE. The switching is done with metals alone.
Sounds like you got it figured out 😀
mine clicks but wont move the motor. i pluged in the motor directly to the battery and it works so its not the motor i wonder what’s wrong

Without being able to see it, make sure only one relay is getting triggered at a time. I posted a link to wiring diagram also.

Is the output to the motor on the 30s or the 87s or does it make any difference?
Can you put the numbers on your diagram for each relay?
ua-cam.com/video/7sQaS6jM3V4/v-deo.html
In this case the motor output should go to 30. It does matter. Negative goes to center or the 87a. Positive goes to 87. Sorry I knew those identifying numbers were there I’ve never used them…lol
I want to use this setup but will be using reed switches for travel limits and a photo eye for the switch. How would I wire in the reed switches?
I have built something very much like that. You would series in the reed switch between the switch output and the relay coil. The reed switch would have to be able to carry the coil load, which should be very low. So when the magnet reaches the reed switch it would open that circuit and the switch wouldn’t be able to send power to the coil. I can try and make a diagram when I can if you need…
@@mikmaster63 I would appreciate that, thank you
I’ve put up a video I think will help. I didn’t have a photo eye. I substituted a manual switch. Check it out and let me know if it helps.

What would happen if both inputs were triggered at the same time?
Not sure how that could happen, but if it did it would just put positive on both sides instead of negative and nothing would happen…
@@mikmaster63 ok thanks I was thinking of using buttons instead of a switch but I think a switch would be better anyways
@@TTTray13467 you would wire it so when one button is pushed the other buttons power is dropped out of the circuit. I would use relays to do that.
What numbers one the relay
See if this helps. Learn how relays work and won’t need the numbers… ua-cam.com/video/J8_ztea3cYc/v-deo.htmlfeature=shared
Hello, is it possible to control such a set but with a joystick?
ua-cam.com/video/H2lro-Ra8pI/v-deo.html about that
I haven’t tried that. Are you looking for variable speed or on/off? What kind of joystick?
I'm interested in switching on and off, it's supposed to be an electric actuator
I think you could just wire in the joystick where the switch is. In this set up we’re just sending positive voltage to the coil of the relay. So the left relay energized moves the motor one direction and energizing the other relay moves it in the opposite direction. I haven’t played around with joysticks so I would need to know which one. I would think any joystick that works like the switch would work easily. If you want it to have speed control check out last weeks video and the one going up later today.
Draw us a diagram for it, please!
As soon as I can
Send me you email i will send you a diagram and a pcb
There is a diagram posted on my page…

SPDT relays?
Yes. The ones I’m using are rated 30 amp

Questa e corrente continua non corrente alternata. Come puoi vedere nel video non prende fuoco. Questo circuito e stato usato per decenni l’ho copiato non l’ho inventato 😀😀😀 sono Italiano ma no parlo Italiano. Ho usato google translate quindi spero che tu possa capire la mia risposta.
