Switches in Electrically Controlled Systems (Full Lecture)

[@Richardo7172]

Man, it's like a light bulb going on in my head now that I have completed this lecture. It's not that i didn't know but it's so much clearer now. Thank you, Jim. Good stuff.👍

Jim Pytel, your generosity for sharing this videos should be greatly rewarded. I m glad, I came across this material.

[@bigbadtech]

Glad you're making use of it. Please tell your friends about these resources!

My instructor uses these videos for class. They make the dry material, contained in the books, much clearer. Thank you, Jim! Much appreciated!

[@bigbadtech]

Very nice! Glad your school is making use of them. I'm presuming you're in the US? Reason I'm asking is I'm applying for another NSF grant and I'm trying to see what other schools are making use of this material.

@@bigbadtech Yes. San Carlos, CA Let me know if you need more info.

[@Richardo7172]

Simple but precise.

[@jordanc3654]

I appreciate the details. It makes a difference if you know what part needs changed, and if you know why the part needs changed and why old electricians always move slow....

I didnt have enough money to make it through school or to get any degree to add to my resume but this guy has helped me stay on top of the job market because its all about can you fix it in my field. I tell everyone that i went to YTU when they ask me what my alma matter is. Thank you for open sourcing this information which is normally held under lock and precipitous studend loan debts... still, missing your "papers" says something...

Thanks you Mr Jim

[@alvinharper9908]

Thank you for this content Jim. I'm in motors 1. This is a lot more helpful than the Amatroll program the school made us purchase to do the same thing.

[@bigbadtech]

Glad I can help! Please tell your fellow students about these free resources!

How can anyone click a thumbs down to this? A Very good Presentation.

[@mohdabo555]

Excellent Thank you for your help

[@marvellousmaphela8138]

Thanks Jim. Your lectures are the best on KZbin. Easy to follow.

Thanks Jim .. I have studied Electronics (basically Optoelectronics, Microelectronics, Semiconductors Technology and such things). Coming from this background, I have poor knowledge when it comes Electromechanical terminology. I really needed this summary to be able to communicate with some colleagues at work. You make it easy, concise and very understandable in this video and many other videos on your channel. Cheers!

[@ghjytffjkk]

very well presented. easily understood… you sir are an outstanding teacher.

[@Automationacademytv]

Thanks Jim right now I'm starting to build my channel and you are my encouragement

Move over control relays lecture I have a new favorite!

[@PeaceMah]

Thank you Jim. Love the videos. 🙏🏽

[@samalfellah2066]

That was a great class 👏

[@davidhaines4173]

Thanks Jim. Looks like you're normally in your activated state. In contrast....I often remain... in a de-activated state.

[@alexguna1675]

Nice 👍

Jim, now i have a question that i need clarity on. At 43:56 we started on photoelectric switches. Trying to understand the sequence of operation. Using a NC switch as an example, when i add power to it first (without the reflector.......not talking about the diffuse type) does the contact change state to NO and when i introduce the reflector it changes back to its deactivated state (NC). Therefore each time the beam is broken it switch to the opposite state. Does that sound right? OR Power added to NC switch, it stays NC and does not change state until the beam is blocked. Please let me know. Thats a piece of the puzzle that i am not sure i fit properly. @Jim Pytel

[@bigbadtech]

You've stumbled upon on of the greatest debates involving photoelectric switches ... are they light activated ... or dark activated? Certain manufacturers assume one definition and other manufacturers another.

I recommend watching these videos at 1.25 x the original speed.
