    If there are people out there that are so stupid they need a USclip video to tell them why a switch makes a "clicky" sound, then, we're in a lot of trouble...well... not I, ya'll, you're in a lot of trouble, I'm not with you all, people that believe the earth is a globe are dead to me, I don't even like to hear the words you say, your individual lives are worth less than nothing, you are one big mass, you all think the same, believe in the same things, you all react the same, you're all programed the same, a Frankenstein-esk monster, a Golem, a puppet...lol, and I know how to make you dance.
    I watched literally 1 second of this video, I bet the guy that makes them is fat, gay, and would molest a kid given half a chance, probably why he makes these videos, you sheep are into some weird sh*t.

    Also, yes, this is stupid dangerous. Just half-arsedly squishing free strands of multi-filament wire down with a screw, half of the filaments not even connecting, instead of terminating them properly with ferrules, is very stupid. And dangerous.

    As a kid, I used to put the switches in the halfway point because I was trying to make the 3-way hall light be off with all the switches pointing down.
    Until my dad said that I could cause a fire. The next 10 years I was afraid to cause a fire. (Then realized that it sounded stupid)
    Guess it just breaks the switch faster

  • David Marcus

    I always admired the simple design of liquid mercury wall switches which are entirely click-free and completely solve the problem of contact degradation from arcing. Flipping the switch simply tilts a tiny vial of mercury inside the switch. The two switch contacts are embedded in one end of the vial, so flipping the switch toggle on simply tilts the vial so the mercury closes the circuit between the two contacts. Flip the switch off and the vial tilts the other way and the mercury disconnects the two contacts, all with no arcing at all. Also, I find the total lack of an audible or tactile click to be somewhat novel, I suppose.

  • Kieorasama

    Please do audio controlled lights next such as having a light bulb that turns off by command of an echo dot. My curiosity is because in order to use the light in that manner, you need to have constant power to it. In other words your light switch needs to always stay in the on position.

    Be careful with hotplugging things like space heaters, you can seriously damage the plug pins. I never encountered it before, because in my country built-in two-pin-unlocking is mandatory, but if you just yank out a plug that arc can really damage the socket and the pins. Apparently, the two-pin-unlocking safety provides enough friction to prevention accidental unplugging when you e.g. move the vacuum cleaner.
    Every time I go abroad, I thank my lucky stars that the Belgian electrical code is so stringent.

    My question is why your space heater's thermometer uses switches rather than a potentiometer.

    • Soitisisit
      Soitisisit 20 hours ago

      @Michael Schagen Thanks! I didn't know that about potentiometers.

    • Michael Schagen
      Michael Schagen 20 hours ago +1

      I'm not an electrical engineer, but I would think it is because heaters draw a large current which would then also have to go through the potentiometer. Due to their construction, potentiometers are not suitable for large currents. It would also be very inefficient as the part of the resistor through which the current runs would effectively have to dissipate all electricity you don't want to pass through your heater. It can only do this by turning it into... heat. So it is only effective to turn a heater either on or off, or have a set of predefined currents going through it using a series of switches activating different circuits.

    I love this video, thank you. Actually, when I was about 7, I used to try and get the light switch on the wall exactly half way between on and off to see what would happen. I imagined the light would just quickly flick off and on by itself if I got the switch right dead center. LOL.

    Props for mentioning GIS (Gas Insulated Switching) technology. Most high voltage switching (500Kv+) is accomplished with very long arc-gap switches in open-air but that takes up a ton of space and is maintenance heavy. GIS can replace a > 2acre switch yard with a reasonably small building (relatively speaking of course).
    If you're looking for a topic for your second channel, then show people the mechanics of an Arc Flash (or flashover). Creating a self-sustaining arc that's instantly hot enough to vaporize copper explosively is generally a day-ruiner.

    Try switching a relay using some 10KHz signal.
    They go whining and switch only half way due to the slow contacts that cant keep up with the 10KHz speed.
    If you can find the exact resonance frequency, the coil in the relay starts whining as well.
    When those two tones resonate, the beep starts ringing and becomes even more annoying lol

    However, be prepared for a relay lifetime of only a few minutes before it breaks.

    Very informative. I live in an old house, and now I have a good idea which switches are original (or at least old). I even have one switch that often clicks (and thus turns the light on/off) about a second after I've already let go. Now I know why.

  • orbik

    Wouldn't it be possible to create a non-clicky switch that still has very quick transition between high/low resistance, by making the contactors compliant, i.e. soft or bendy. So even when the circuit closes fast, the kinetic energy is given more time to dissipate afterwards, thus not creating a sharp discontinuity in air pressure a.k.a a click sound.
