    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?

    I really admire the amount of effort you put into the production of your videos, you even go as far to make subtitles and as someone who watches everything with subs if it's available i appreciate that a lot, thanks for making such interesting content man.

      That was interesting even though I thought I knew the answer to start with. Which I did but hadn't ever really taken a good look at the innards of a switch

                heres another question: why is the voltage lower in the US than here in europe? lower voltage means more current for the same power.

                  I have a panel from an elevator and its switches can take literal seconds to click after flicking. Scary but cool.

                          IF there was a light switch which was Quantum in nature, would the light be both on and off? Don't even go there with the cat example…!

                              I was hoping it'd explain why my old house has switches you can hear from a mile away and modern switches are quiet...

                              oh dang it does. 10:32

                              I thought this video was going to be some useless information but it's actually pretty relevant.

                                Those super clicky switches, with real spring loading, in your old house are still available. They are out of favor because the cost a few cents more and some folk do not like the loud clack noise.

                                Also insulator-conductor spectrum is not really true, at least it is an over simplification. While it is true that most conductors have some resistance(exceptions are called super conductors) the resistance should be thought of like wind-drag on a car or water-drag on a boat. A true insulator on the other hand has zero electrical leakage within its design envelope(mainly temperature and voltage gradient), an insulator is not simply a high resistance conductor. To be sure many materials have manufacturing defects that allow some leakage but this is generally not the bulk of the material but isolated channels, most notable on very thin insulation such as those found in capacitors, where the defects have a high chance of being the full depth of the insulation layer.
                                Now under certain conditions the insulation property can be broken and allow electron flow, thus turning an insulator into a conductor. Think of the insulator like a brick wall to the car, which prevent the car from moving at all up to a certain effort at which point the wall crumbles. This is what happens to gases in an arc, the voltage gradient becomes so high that the outer electrons of the gas are popped loose creating charged ions, charged ions will allow substantial electrical flow and the heat generated by the resistance helps keep the gas ionized even though the voltage gradient is much lower with conduction than it was before conduction.

                                Now you may be say "Wait! What about surface leakage on PCBs?"; Well that is not flow through the insulator that is flow creeping across the surface of the insulator due to the molecules at the edge of the material having loose ends so to speak, without a matching neighbor the charges may not be fully bound and the surface becomes a high resistance conductor.

                                And to cover another point, insulators generally do not block the electromagnetic field around electrical charge and flow which is capable of transferring energy without any exchange of electrons. Thus electricity can [up to a point] appear to flow through a capacitor or transformer though no electrons are actually crossing the capacitor or transformer.

                                      Mr. Technology Connections man, I'm surprised you didn't discuss the old "silent" light switches which used mercury to make and break the circuit without noise.
