Even though I've been in the trade for over 20 years I still enjoy watching this channel... never know where you might pick up a new trick or different/better way to do something. I send my apprentices here all the time. Excellent channel
The day that we are too “old” to learn something new is the day someone should check us for a pulse . 😂👍
Thanks!
The graphics are outstanding Craig 🤘⚡️🤘✨
Magnificent, Mr. Migliaccio. I love the way you break down the bare bone necessities for electrical switches. This is a fun way to memorize and learn.
Not the first time I've said this on one of your videos, but on Monday, I'm going to show my new helper this video. Excellent resource for new techs and great refresher. Keep up the great work. 👍👍
This channel is the best of the best. Above and beyond in every video!
Thank you for helping me. Greatly appreciated.
Excellent, I try not miss any new posted video, because i do know how much knowledge i could lose, if I don't watch it, simple as that,.
Thanks teacher for your sharing your knowledge.
Awesome videos. I just bought the book, workbook and card combo tonight. Can’t wait to get them and use them.
Awesome and please let me know what you think of them after reading!
Great way to learn the types of switches.
Glad you think so!
Nice explanation, Craig. With schematic symbols, too.
Glad you liked it!
good stuff Craig!!!!! thank you again for sharing! your awesome man.
I like the videos and they are very well explained
Nice video. Great knowledge and explanation.

شكرا جزيلا على كل ما تقدمه لنا من فديوهات رائعه شكرا لك استاذ
Great content
I love this channel
Cool.........Thank you....👍👍👍👍👍
No problem 👍
Great videos 👍🤝
it's more common to be listed with a number for pole designator, after double pole, 3PDT or 4PST ... 8PST.
I don't recall seeing many schematics or much labeled as TPDT, although it's correct to do so :)
Do you have a video on the DC rectified relay switches? I see them in carriers for heat strips sometimes. Why are they even used? They sometimes confuse me for the first few minutes lol
Number thirty-four...👏🕊👍
What would happen if you wired that single pole single throw pressure switch backwards? Would it not work?
Believe it or not, the most important statement you make in the entire video is that the NO and NC relay contacts are identified in the coil DE-ENERGIZED state. You have no idea how many “engineers” don’t understand this concept
Lol, all of the engineers don't get this, I heR ya totally :)
Nice job and video
Thanks for the visit
SPST if you want to look cooler enabling each one
Good video.
