More on this clever device
https://en.wikipedia.org/wiki/Centrifugal_switch
*The oldest patent I could find was from 1926. But it seems to have been in regular use by then making me think variations are likely much older than that.
*The comment about “specifically the US” is about single phase power… Countries that have three phase power use 3 phase motors which don’t need a kick start. We have both 120 and 240 in the US. The motor in this video is 240

Great info. I have heard that clicking sound thousands of times never knowing what causes it. Thanks for the excellent video… Subscribed.
Excellent video content and presentation! Great work on lighting, sound and camera composition and operations. I love the enthusiasm for smart, efficient, mechanical devices. Very interesting video!
If u were my school teacher ; I never would have left my school to do family business
this device is called Governor first designed to control the fuel injection to the engine u can find extra info here:

Dude, slow down, your blowing my mind! Lol!🙋😁
The governor
That was a very informative and interesting video. Nice job!

Thought this might be an honorable mention.
THANKS Jeremy
Not sure how I got here, but I stayed for the voice. You would make a great teacher/prof.
Anyone ever tell you you look like that actor in the movie “the lady’s man”? Lol 😂. Very cool and informative video. .
Hello! The comment about "specifically the US" is about single phase power… Some countries (like Germany) have three phase power and don’t require a start winding. We have both 120 and 240 volts in every house in the US. In fact the motor in this video is 240 volts. So what is single phase? I explain that in this video. https://youtu.be/2XYdTogWcIA
If I was forming an Ocean’s 11 style crew, I would seek out Jeremy and tempt him with a suitcase full of cash and access to a previously unreleased mechanical technology.
Thanks for the video dude! I just had to subscribe!😁👼🙋
I wonder if it’s a Tesla invention from the early days of motor design?
If I had just one teacher like this, maybe I would’ve been successful.
It’s a starter,so what are you looking for,an idiot,?
Very common also in speed governors for farm tractor, irrigation pumps, welders, and power units. They have a gradual ‘ramp’ they run against applying variable amounts of throttle, and not just a snap on/snap off operation.
I just stumbled upon your videos. Thank you so much
I wonder why I have never seen one of these things before?
Being a 71yo woman, I confess that I have always been interested in tools and how things work. I lost 2 washing machines and one dryer because that little thingy broke. If I had known about that, and had some sandpaper, I could have probably fixed them. Now I know what to listen for, and can’t be fooled by repairmen saying I need a new whatever. Thank you for the info.
One thing i will add is that the switch was also open because of adjustment. That external switch needs to be set to close the circuit .
Why would anyone dislike this cool video is beyond me!
Excellent video! Flawless prep and message delivering too.Congratulations !
The switch is basically a steam engine/combustion engine governor. That’s why there’s not really an inventor, the design just got adapted.
This is an extended application of the speed governor used in engine’s. The inventor is James Watt.
Jay Leno’s garage! Steam cars!
It known a cluch plate as well as centrifugal switch. It disconnect primary winding to running winding. I am not a iitian nor a technical person. I am a government teacher (primary school) in india🙏🙏🇮🇳🇮🇳🇮🇳 i am ready for hire
I am still wondering how to determine what two wires go to the starting circuit and what two wires go to running circuits in the washing machine motor? Also, How do I determine if a motor has a running capacitor circuit and or starting capacitor circuit. How to determine them by ohm reading which is assumed that there are no circuit diagrams anywhere? Thank you very much in advance.
Thanks,Jer.
Reminds be of the “balls out” feature on steam engines.
Royal Lee
A 1920’s patent for a centrifugal switch (US Patent #1,630,394) was granted to Royal Lee on May 31, 1927. It was the basis for the formation of the Lee Engineering Company.
According to Google https://patents.google.com/?inventor=Victor+E+Johansen this is the inventor of the switch.
Look up steam engine, force
Please feature about another simple device the wrap spring clutches.
Hahaha, or gal. Hahaha haha yeah right Bro. A woman couldn’t possibly even conceive of such beautifully complex simplicity. Hahaha, my wife thinks fire shoots thru electrical cords, hahaha, Fire!!!! I told her not to worry, it isn’t fire it’s LAVA!!! Hahaha, and she believes me, hahaha haha. You’re too funny Bro. 👍🏼
Looks like the governor on an old steam engine! It’s where the expression balls out comes from! See for yourself on jay Leno’s channel!😁🙌
Oh yeah! I know what that is, it goes in the motor! 👼👏
Very informative! Great video sir!
work on motors brushed induction and this switch is only backward us technology we use other more smart devices very good example of backward technology in us is trucks still no tcs and ecs braking systems max is abs and crash non synchronised gearboxes enjoy but this is very us backward fire creating technology
Invented by James Watt to regulate the speed of a steam engine and it used 2 opposing balls as the weights to govern the steam engines speed by controlling a valve to the input. A form of negative feed-back. The mechanism was also known as the governors balls.
Dang! Now he tells me unplug the machine! Lol!😵
Speed
As far as USPTO is concerned, it was patented by Royal Lee of Lee Engineering Company in 1927. It looks similar in concept to some mechanical governors, though this one opens electrical contacts at full speed.

Very interesting video. Well done.
Over the weekend my aged table saw stopped working. Classic "hum and won’t turn". Shaft is free to turn, bearings still feel good. Since I had _just_ watched a bunch of these motor videos I knew it had to be the starting cap or something to do with the centrifugal switch. I ordered a cap just in case (and to use as a known good test in case it _was_ just a blown cap — I tested first as you rightfully advise in this vid!), and when it arrived I dove in. Sure enough, after all those years of switching AC the centrifugal switch had fouled contacts — the cap wasn’t even attached to the motor (or was attached through a giant unintended resistor). Clean up and adjust the gap of the contacts, blow out the spiders and sawdust, check the sealed bearings, and it was good to go.
Personally like the fact that he didnt delete the mistakes. This is important to trouble shooting to allow the trainees / followers what not to do along side with what to do. He also is informative and precise. Subbed and Appreciated.
This is a derivative of the Centrifugal Steam Engine Govenor invented by James Watt to prevent Steam Engines from overspeeding and disentegrating. The mordern one just controls electrons instead of steam but they work the same way: https://en.wikipedia.org/wiki/Centrifugal_governor#:~:text=James%20Watt%20designed%20his%20first,had%20employed%20for%20steam%20engines.
