    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.

    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

    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

    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 :)

    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
