      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.
