   I am building a model railway power controller and this explained all I needed to know. Thanks.

2. 

   Does it the switch matter if I'm running four 12v car batteries in a series circuit.

3. 

   Great info my friend….could you also use 5 pin relays to manage amps.

4. 

   Brilliant description just what i was looking for Thanks

5. 

   Why do I feel like I'm in a mission impossible movie with someone telling me vital information to save the world. But thanks for video. Learned what I needed

6. 

   Diodes, who needs them! seek out circuit solver on the playstore!

7. 

   Thanks for explanation will these switches work on a 12volt motor

8. 

   THANK You. I had drawed exactly the same on a piece of paper but wasn't entirely sure it would work. Your website (and not Video) helped to clarify. Thanks!!!

9. 

   Best and Clear Explanation! Just like your many other interesting videos. Needed this info for building a small linear actuator using an old cordless DC drill motor. Thanks a Bunch!

10. 

    very good explanation .Thank you

11. 

    4:21 "would'nt reccomend controlling large motors this way"
    at what voltage of motor would you say this becomes a problem?

12. 

    very easy to understand, thank you

13. 

    Sir, I have an existing common auto relay switch and do not want to remove. Can I wire a DTDP switch after the existing relay in order to reverse the electric motor?

14. 

    What kind of wires are being used at 2:40?

15. 

    Best explanation ever on DPDT and reverse polarity. You are a a god sir.

16. 

    Fantastic video and explanation. Congrats and thank you.

    What's considered a "tiny motor?" I have 12v/1.1a brushed DC motor that's run off three 18650 batteries in series.

18. 

    I am writing two comments because this is probably the best explanation

19. 

    Ok you again?!?! Obvious your videos are the best explanations of RC and relays. Liked and thank you !

20. 

    Loved the concept and presentation and warning ⚠️ about its applications. I have a very interesting question? Could you not wire a heavier guage 3 way on a rotisserie motor?🤔🤔✍️✍️🧐

21. 

    The BEST explanation of DPDT EVER! Finally got my baler able to wrap the bales. Thank you!

22. 

    Excellent! Thank you!

23. 

    I've spent all day mucking about with a rocker switch and drill motor. Thank you for your explanation, hopefully tomorrow I'll get it working both ways now.

24. 

    very well explained can you wire a 2 speed wiper motor to go forward and reverse in slow on one and fast on another.there are three wires on motor red, blue and green .I can reverse the motor with one dpdt switch can the second switch be used for the other speed

25. 

    Hi
    I make all kinds of stuff with those wheel chair motors.
    And we use the Sabertooth motor controllers.
    Where did you get the gears?
    How did you make the tank tracks?

26. 

    i thinking about it to do it how? now i know it ,,Thank you very 🙂

27. 

    Is there an automated version of a dpdt switch?

28. 

    Electrons actually flow in the opposite direction of your diagram but still it's a good video =]

29. 

    2:35 That explanation with the diagram was pretty useful. thank you!

30. 

    Best description I've seen of a double throw switch.
    The diagrams are REALLY good.
    Well done.

31. 

    …and this is how your power window switch works

32. 

    Would corvette headlight motors be considered large?

    Beautiful explanation of how to use a DPDT switch to reverse polarity to a DC motor. The diagrams at 2:55 to 3:48 are extremely helpful. Not to make things more complex but I have another question: Instead of "jumping" the red terminal across the back of the switch, would this system still function if I ran two separate red wires all the way back to the DC power source? (Or blue. No difference.)For my application, let's say that my motor is "running a flag up a flagpole", and I want a microswitch to cut power once the flag is at the top, even if my finger is still pushing the DPDT toggle. Then, I want to run the flag DOWN the pole and have a second microswitch cut power again at the bottom? One DPDT and 2 NC microswitches for 3 switches total. Make sense? Thanks so much.

    Hey I seen another fan question below, but I didn't get any clarification from it. As the OP never answered back. So I have an old steel fan with three speeds. Its has about an 18 inch blade and does not oscillate. It's a product of the forties, and the dial knob has snapped off. The fan still runs fine, but no switch. It's for the Bantams coop as it's very hot in Florida right now. I've got it jerry-rigged up to cool them but I don't want it to burn anything or start a fire.
    So I have an 8 pin DPST? ? slide switch laying around, and thought it may suffice. I dont need to reverse any rotation just the three speeds. How could I accomplish this. I hope this makes sense.

    Thankyou in advance, for taking the time to read this.

35. 

    does it work on universal motors ? ( ones that use electromagnets instead of Permanent Magnets ) taking a AC/DC power source. or this is solely for DC motors ?

36. 

    I've got an illuminated on-off-on switch with 7 pins. Can it be used as reverse polarity switch?.
    Trying to add reverse to a Razor quad.

37. 

    How do the red and the blue cables are called , at 2:39?

38. 

    A very good demonstration in the implementation of DPDT Switch

39. 

    Was reverse polarity used in making this? https://www.youtube.com/watch?v=kaJVWoKj2a4

40. 

    Would a 115V fan motor be considered a large motor, & is a DPDT switch safe for that motor?
