Hello:
I want to tell the students something. It’s a quote from the composer Igor Stravinsky, which says the following:
To always follow the same path is to go backwards.
And I’ll also tell you something else, for a wise man, a few words are enough:
In my 35 years of experience as an electrical installer, I’ve performed many lamp switching operations (turning on and off from two points), and therefore, I’m one of the most qualified people in the world to explain how to perform a two-point switching operation, or a three-point switching operation, or whatever, with their intersections. Despite this, I will never, ever make a video about switching operations on YouTube, NEVER, because there are countless of them, there’s a lot of information about switching operations… I think I’ve been explicit enough. If you don’t understand, feel free to ask anything you don’t understand…
Here’s the quality control project that is capable of replacing parts so that both combinations, operator and machine, match:
