    Click clack I was taken aback. Wonderin’ ‘bout those switches of light, yeah.
    Let’s find out what the point is of all that clacking, shall we?

      They click because of the need to make a quick connection between the contact points in the switch. As the connection is made there is an arc between the contacts, a slow connection would reduce the life of the switch.

            Leviton's top-of-the-line switches are quiet. A loud click isn't necessary to achieve fast make contacts. Also, does this video qualify as click-bait? 😁

                    do you film yourself or do you have someone film you since i would imagine it would be rather annoying to constantly get up move the camera and then sit down again

                          Oh, so I guess that thing I did as a kid where I jiggled the switch back and forth to mess with the lights was a bad idea... Well, now I know.

                                  Sorry this is click bait...TD and forwarding this vid to OSHA as... Only a moron would allow their eyes to be that close to an electrical arc without approved safety protection... BTW mercury switches do not make a click... and the electrical arc is insulated by being contained...

                                        I like how he said 'nothing is a perfect insulator' because having nothing around a wire is not even air is literally a perfect insulator.

                                              there is another way to prevent arching in relay switches. a diodd is placed parallel to the coil of the switch so any remaining charge will go thorough the diode instead of the air gap

                                                  I also liked the brief mentioning of the "completely safe" plug but without saying that honor goes to the British plug. And there is a new possible episode. Plugs are amazing. Simple but very different all over the world. Technology Connections should in my opinion explore those in a future episode.
