When I was young I used to try get the very old switches to sit in the exact middle. I now understand why I caused so much damage and got in so much trouble.
we had a 3 way switch on our stairs, to annoy our other siblings we would put the bottom one in the middle position so they couldn't use the switch at the top. being a dumb kid, we didn't think we were doing anything wrong. it wasn't until I moved into my own house and had a really poor switch in my living room that would "fizzle" when you turned it off that I realized what I had done as a kid.
@@krypticviper1613 Electric arcing happens. That tiny spark is really really hot and eats away at the contacts inside the switch. You want zero resistance in the switch. But as damage and burnt gunk builds up, that resistance can increase and eventually you got a fire hazard.
They're probably surprised hearing how the humans around them keep talking about "switches", when almost any other region calls them by what they actually DO: cut off the current to nothing, not switch between two alternate options for the current to flow. A rail switch is a real swich, because there IS another rail in the other position.
Awwww, you didn't mention turn signals! The "click, clack" of turn signals used to be caused by the relay that controls the bulbs toggling on and off. Now cars use solid state relays, so the clicking sound is produced artificially by a speaker under the dash.
Used to specifically be a bimetallic strip that heated and disconnected and cooled to reconnect on a regular cadence. My 2015 car actually plays the turn signal sound through the stereo speakers. ^_^
As someone who's been on TH-cam since early 2012, I grew very tired of those people that say anything remotely do that. It even makes me cringe whenever I make myself say it.
Nice click sound is also good positive feedback. The positive feedback is very important in the human design. It makes things intuitive and giving you info "you doing it right"
Agreed. The silent mercury based switches that were in my house when I bought it were a little awkward. Before I realized they were mercury I thought they were worn out and I really missed that 'click'.
If I didn't click, and there's some electricity outage or defected bulb/ device. People would have just keep pushing it, thinking it haven't reached the end and closed or opened the circuit. It's a nice feedback.
Haha. Joking aside, get a can of electronic spray cleaner and spray directly into the opening under the stick's flap. It'll dry up in 5 seconds and immediately clean the circuit up. Worked very well for me.
Also i worked in a firm designing fuzes (yes that how its spelt) that made missiles operate and that was always explained as "the thingy that makes it go bang" to the people above our pay grade
In fairness, that can be a useful way to trick fluorescent tube lights with dying ballasts into igniting properly. The sudden current cuts and starts can play into the magnetic tomfoolery of the ballasts in such a manner that you can push the voltage over the hump to get the ionization going full-bore, or at least half-bore, which will often self-correct in a few minutes. It's terrible for the ballasts, but they're dying anyway if you're resorting to this.
I did that once on accident by half ass throwing the switch. I was perplexed by the way the light was acting figured the bulb was loose. Took the globe off the light and checked the bulb and it was tight. Figured I had a bad connection under the fixture. So I go to turn off the switch and it is making an angry 60hz buzz and was VERY warm. I'm guessing here but I can only imagine I had the switch on just enough to sustain an arc across the contacts. And I went right to the hardware store and got a new switch immediately.
@@EgoShredder Fuses and circuit breakers only detect overloads and short circuits, not bad/loose connections and sparking, well except for the newer arc-detecting circuit breakers, which are not all that widespread yet? But do those very often trip off for just no reason? Modern digital lamp timers and digital thermostats, use a relay or mechanical switch mechanism which provides that instant-on, instant-off snap action that a switch is supposed to do. Hopefully, they would be rated for at least 15 amps, and use a heavy-duty relay that can handle switching on a window air conditioner or heater, and not merely a low-current lamp. Even though the most common usage would be to control a lamp.
I just figured the clicking is the plastic slapping against the back of the switch when you push it, because if you push them very gently there's no click
yes there are different ways the common toggle switch is made. cheapies can use a plastic arm that bends and slaps. might only work 10,000 times or less then the arm fatigues and tho the switch will still work, it's not clicky any more

When I was a kid some houses had silent switches that had a vial containing a small quantity of mercury. Two metal contacts were at one end of the vial. When the switch was off, the vial was tilted so that the mercury was at the far end. When it was on, the vial was tilted the other way, and the mercury would complete the connection between the two contacts.
Some video game controllers in the 80s also used those mercury tilt switches to attempt to simulate motion controls. Some actually worked pretty well, but if you broke the controller, you're gonna have a bad time.
Where I'm from they used mercury switches on car bombs, when the car started accelerating the mercury would be pushed back in the vile onto the contacts, completing the circuit, blowing up the cop or whoever it was being targeted

Just behind the house where I grew up (about a mile from a power plant), there are a series of high tension towers, with dozens of power lines heading out over the region. We used to stand beneath them with fluorescent tubes and play light saber, because they would light up as you held them. Don't know why this memory came to mind, but these videos always make me think.
That sounds rather dangerous. In India there have been incidents of people getting electrocuted because of standing in the fields below the high tension power line. Max high tension power lines (11,000 Volts) are now built on absolutely gigantic monster poles to maximize distance between the ground and wires.
That's an old Navy prank, too. You round up some new guys for "lighting maintenance" and collect a bunch of fluorescent tubes from anywhere they won't be missed for a few minutes, then go up to the aft deck. The seasoned seaman explains that they just need to give the tubes a vigorous shake to loosen the stale phosphors, demonstrates - and his buddy up at the radar controls hits the beam for a moment, making the tube light up.

@@nitePhyyrethe effect of field emission was being utilized in the electronic lamps (predecessors to present day transistors).

Yeah, x-ray machines also come to mind. And other electronic gadgetry. As for vacuum, a perfect vacuum is just theoretical concept which can't be achieved in real live. The electronic lamps would contain something like good-enough vacuum, subject to technological and economical constraints, yet subjecting their void to space-level vacuum wouldn't probably affect (improve) their performance one bit.
With sufficient caution, you can also use it "in reverse" to plate material onto a conductor, though admittedly a more conventional version of welding will usually be better.
Yes conductive drilling and cutting is an industrial standard since quite a while and it allows for precise and quick results. And as mentioned, the reverse thing is light arc welding, it works mostly the same.
I'm a little sad that there wasn't "A switch is a piece of networking equipment that can organize traffic packets depending on if it's managed or unmanaged... Wait." But the IT Gods will give it a pass.
Actually, the switching layer predominantly routes the individual packets to their intended destination port(s), effectively a very primitive router, switching between ports on a per packet basis as well as resetting the timing allowing for longer runs between two points (up to 200m max path versus 100m). As differentiated from the dumb repeater hubs of ole that simply broadcast every packet to every possible port (though such are/were very handy for snooping all traffic).
I'm also sad that there wasn't "A switch is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via search and map."
rebmcr You got me! I do appreciate the correction as I was drawing a blank earlier when trying to recall the correct term - my memory isn’t quite what it used to be!
Yeah I have 'switch dimmers' and don't really understand how the work, technically. It's all about timing. If I hit the switch quickly, the lights go on (or off). If I press and hold, the dimmers oscillate between high and low and will stop wherever and whenever I release the switch. How do these work???
@@WowIndescribable There's a little computer chip that's reading the button and controlling the triac that's varying the current to the lamp. If there wasn't a computer, you could do it with an electronic circuit with a few dozen components. But fortunately there are single chips now, with a computer, memory, and program storage, as well as input / output, all on one little chip, costing just a few pennies. Actually they've been around since the 1980s, it's why there's a lot more smart stuff about now. As computers, they don't compare to a PC or a tablet, with only a thousandth the RAM and CPU performance, but that's still plenty for a light switch or a microwave oven timer. The slightly more expensive ones, but still just a handful of dollars, have Wifi and Bluetooth on board. Hence all these Wifi house plugs and video cameras and stuff that are all over the place recently. These ones compare to PCs of perhaps 20 years ago, that still got on the Internet, except they're optimised for what they do, not needing graphics and disk drives like a PC has.
Over Christmas, my parents and grandparents were talking about how back in the 60's they tried installing rubber power outlets. After that, the found whenever there were storms those plugs would spark so badly that they could see it arcing halfway across the room. My grandpa didn't believe them at first, until he saw it himself. Needless to say they immediately switched those rubber outlets back out.
I usually turn off lights slowly (without hearing a click) since I figured the clicking was worse than no clicking in terms of wear, turns out I was really wrong.
same... this is why I always close my eyes plugging this in or unplugging them lol... and electroboom literally gave me a decent amount of heart attacks in the past...
Never come to my shop. I have 240 VAC 100 amp sockets for my big shop equipment. You wanna see a big arc pull one of those out when running one of my bigger machines!
Fun fact: switches designed for DC have to be even more rigorously designed due to the fact that normal current flow never goes to/through zero like AC power does.
In the home I grew up in, my dad specifically installed silent light switches everywhere. They used a drop of mercury and gravity to open and close the circuit. Yikes. I remember playing with them as a kid, moving the switch as slow as possible to see just when the lights would come on.

Because all modern dimmer switches use a component called a Triac to essentially "chop up" the AC waveform so the light being dimmed doesn't see the full AC wave and thus appears dimmer. It's called PWM or pulse width modulation. I'm sure TC would do a MUCH better job explaining it though so I hope he does.
@@VideoGuy84 what you say is correct, but a triac/diac type dimmer does not use PWM. It is really similar, but it's defienetely not the same. Pwm alternates between 1 and 0, a triac just lets some amount of the wave pass and stops the rest.
What about why CFL and some LED bulbs are not compatible with dimmers? I’m probably gonna answer my own question by assuming it’s because they are ballasted lamps that need the full current of a hot wire to power the ballast, so their either completely off or completely on. But that wouldn’t apply to dimmable LED bulbs.

It feels very reminiscent of those old vehicle educational animations from the 60's and 70's, where they did the same thing and also made it fun to learn something new.
A hundred years ago they were even louder. Our old house had switches with a porcelain body, and the switching mechanism (yes, a spring and some brass and bronze connectors) was what we could call "long throw, double-wiping, double break". Long throw means that breaking the circuit was not merely a movement by a two or three millimeters but 20 mm or more. Loud as heck. Descriptions of double-wiping contacts and double break can be found on some internet somewhere, and are left as an exercise for the truly curious.
Then there's my Grandma's House, which still has many Mercury Switches in service. Completely quite and smooth action as it uses contacts on one end of a sealed glass vial containing a small amount of liquid mercury. When you tilt the switch, the mercury either flows away from the contacts, breaking the circuit, or towards them, connecting it.
We have a bunch of them, because my father and grandfather from the other side had to be wrestled away from hardware stores, like drunks from bars, or they would burn up their wallet buying junk for which they were sure they could find a use.
i have quite a few myself, i found some for sale in a box and bought every one i could get my hands on, i have only used one though, but they are fantastic for outdoor use, as the contacts cannot corrode and will probably last almost forever i'd think

Honestly, having grown up traveling and using various plugs: British plugs aren't as safe as you think they are. They conveniently accept screwdrivers and European-style plugs quite easily, leaving large open areas. They are robust - but for most practical purposes the European-style plugs have most of the advantages without the disadvantages. US's plugs just suck though.
Buckling springs deliver excellent clicks in every scenario. It's also worth checking out Big Clive's videos on circuit breakers to see how extra beefy switches work.
@@lazymass And then you have single pole/single throw, double pole/single throw, double pole/double throw switches. What he was showing was a single pole/single throw switch, which is the simple on/off switch in 98% of your house. But if you have a stairway or hallway, or a light by the backdoor that you want to control from the garage, then you need a 3-way switch. That's the one with 3 terminals and no on/off marking on it, because it is only on or off in relation to the position of another 3-way. Also if you only have a 3-way it can also be used as a simple on/off, just use only 2 of the 3 terminals. Now what if you have a room or stairway with over 2 entrances? The 4-way switch, with 4 terminals comes to the rescue. 2 3-way switches are used, and every added doorway gets a 4-way.
If you want to simulate those ugly, bulky, huge plugs favored in the UK and Australia, just glue a huge thick piece of plastic to all your plugs :) Of course keep in mind that we have huge plugs on 240 volt stuff also but our normal sockets are 110-120VAC, so roughly half the voltage of UK power.

@@theodiscusgaming3909 The prongs aren't quite as long I think. A larger contact surface also makes it safer to draw more current.

4:17 "Everything conducts electricity when you try hard enough" (Shows a lightning strike) Man, a couple years ago I was working for a company that builds lighting protection systems, and it was so fascinating to learn about this kind of stuff that I didn't know that much about as a kid. When lightning hits something, all that electricity WILL find its way to the ground, and it doesn't much care about what kind of material it is. I was looking at photos where unprotected buildings got hit, and there were freaking BRICK WALLS that were ripped apart from the strike, and I began to realize that fundamental truth of electricity that, yes, with enough of it, you can make it travel through ANYTHING.
Yeah its realy amazing That The same ENERGY is stored in every existing matter and so will travel through it if forced enough. Its really baffeling actually how everything is setup in this univers.... Never stops to amaze me
Well sort of its not really going through the brick more that it breaks down the molecules and atoms. Yes it goes through the brick if you look at it, but rather is jumps from the water inside the bricks or anything that is in the brick itself (glass pieces for example) At that moment the brick also breaks because dielectric breakdown happens, which means the electric field exceeds the breakdown voltage. Breakdown voltage is where an insulator basically has its molecules crack under the voltage. Everything thing in the world has a different limit (air for example has 3Kv/mm limit) So what basically happens is that lightning happens and it starts to break everything on its path. It will still find the easiest way. But everything that does breakdown turns to plasma. Which is why the brick breaks down. This is because the voltage field is too high (which in lightning is seriously high) and it manages to make a jump with an arc and that arc turns everything in the path to plasma. Lightning can also happen without ever reaching the earth (sometims going kilometers across clouds), this means it isn't able to break down the air under the cloud enough to reach the earth. In short insulators have a lot of electrons close to the atoms this makes it near impossible for current to flow. Air for example can withstand 3000 Volt every millimeter until it breaks down) If the electrical field goes over the voltage limit, suddenly it manages to grab those electrons and bumps them into atoms etc, which ionizes the atoms and you can charge them. But thats only because the voltage was higher then the materials could handle in the bricks (which isnt much). Lightning has around 1billion volts. this means that you need to have an insulator that can withstand 1 billion volts. A perfect vaccum for example will never have lightning go through it (perfect vaccum has nothing to carry it) Diamond for example has 2 million volts dielectric strength per meter. So 500 meter of diamond would withstand a lightning blast and it would nothing.
@@PhoenixNL72-DEGA- No electricity will never go through a real vacuum, in a real vacuum there is nothing to carry electrons around so there is nothing to charge. Crt screens and arc lights do not have real vacuum. CRT screens have 0.01 pascal or 0.01 millibar. So not real vacuum meaning there are still electrons in the near vacuum (otherwise you would be able to see light) Same for the ARC light which contains gas to make the arc. Again if you have true vacuum you wouldn't been able to push electricity through because there is nothing to push it.
One more detail: the contacts in switches are made of a material that resists damage from arcing (unlike the brass or nickel plating of a plug and receptacle). One common material is phosphor bronze.

In fairness, that can be a useful way to trick fluorescent tube lights with dying ballasts into igniting properly. The sudden current cuts and starts can play into the magnetic tomfoolery of the ballasts in such a manner that you can push the voltage over the hump to get the ionization going full-bore, or at least half-bore, which will often self-correct in a few minutes. It's terrible for the ballasts, but they're dying anyway if you're resorting to this.
I... Think your nintendo switch is broken
I did that once on accident by half ass throwing the switch. I was perplexed by the way the light was acting figured the bulb was loose. Took the globe off the light and checked the bulb and it was tight. Figured I had a bad connection under the fixture. So I go to turn off the switch and it is making an angry 60hz buzz and was VERY warm. I'm guessing here but I can only imagine I had the switch on just enough to sustain an arc across the contacts. And I went right to the hardware store and got a new switch immediately.

Fuses and circuit breakers only detect overloads and short circuits, not bad/loose connections and sparking, well except for the newer arc-detecting circuit breakers, which are not all that widespread yet? But do those very often trip off for just no reason?
Modern digital lamp timers and digital thermostats, use a relay or mechanical switch mechanism which provides that instant-on, instant-off snap action that a switch is supposed to do. Hopefully, they would be rated for at least 15 amps, and use a heavy-duty relay that can handle switching on a window air conditioner or heater, and not merely a low-current lamp. Even though the most common usage would be to control a lamp.
I just figured the clicking is the plastic slapping against the back of the switch when you push it, because if you push them very gently there's no click
yes there are different ways the common toggle switch is made. cheapies can use a plastic arm that bends and slaps. might only work 10,000 times or less then the arm fatigues and tho the switch will still work, it's not clicky any more
There's still a click, you've just constricted the motion such that it doesn't report like it would otherwise.

When the switch was off, the vial was tilted so that the mercury was at the far end. When it was on, the vial was tilted the other way, and the mercury would complete the connection between the two contacts.

Just behind the house where I grew up (about a mile from a power plant), there are a series of high tension towers, with dozens of power lines heading out over the region. We used to stand beneath them with fluorescent tubes and play light saber, because they would light up as you held them. Don't know why this memory came to mind, but these videos always make me think.
That sounds rather dangerous. In India there have been incidents of people getting electrocuted because of standing in the fields below the high tension power line. Max high tension power lines (11,000 Volts) are now built on absolutely gigantic monster poles to maximize distance between the ground and wires.
That's an old Navy prank, too. You round up some new guys for "lighting maintenance" and collect a bunch of fluorescent tubes from anywhere they won't be missed for a few minutes, then go up to the aft deck. The seasoned seaman explains that they just need to give the tubes a vigorous shake to loosen the stale phosphors, demonstrates - and his buddy up at the radar controls hits the beam for a moment, making the tube light up.

"A switch is a piece of networking equipment that can organize traffic packets depending on if it's managed or unmanaged... Wait."
But the IT Gods will give it a pass.
Actually, the switching layer predominantly routes the individual packets to their intended destination port(s), effectively a very primitive router, switching between ports on a per packet basis as well as resetting the timing allowing for longer runs between two points (up to 200m max path versus 100m). As differentiated from the dumb repeater hubs of ole that simply broadcast every packet to every possible port (though such are/were very handy for snooping all traffic).

@@WowIndescribable There's a little computer chip that's reading the button and controlling the triac that's varying the current to the lamp.

You should do a follow up video on dimmer switches, how they work, and why some lamps create a buzzing effect on them.
Because all modern dimmer switches use a component called a Triac to essentially "chop up" the AC waveform so the light being dimmed doesn't see the full AC wave and thus appears dimmer. It's called PWM or pulse width modulation. I'm sure TC would do a MUCH better job explaining it though so I hope he does.
@@VideoGuy84 what you say is correct, but a triac/diac type dimmer does not use PWM. It is really similar, but it's defienetely not the same. Pwm alternates between 1 and 0, a triac just lets some amount of the wave pass and stops the rest.
@@somedude2492 I stand corrected. I'm probably thinking of low voltage LED controllers which do use PWM.
What about why CFL and some LED bulbs are not compatible with dimmers? I’m probably gonna answer my own question by assuming it’s because they are ballasted lamps that need the full current of a hot wire to power the ballast, so their either completely off or completely on. But that wouldn’t apply to dimmable LED bulbs.

@Simeon Walker 1500 watts
I didn't laugh about that sweetly naive comment.

Well yeah, the UK's 230V can carry much more energy through thinner wires than the US's 110V. Course you could also get shocked really badly and possibly die, so yeah it's a bit of a trade-off. ;D
After watching the video i immediately went and clicked the lightswitch in my room a couple of times. How great to live in a time when we have little things in our houses that make satisfying noise
"We designed plugs that would, depending on your country, somewhere between somewhat safely and completely safely allow you to make and break electrical connections". Never been so proud to be British! There's a great video about British plugs on Tom Scott's channel.

1:41 Aww man, I was hoping you'd describe a network switch
shelvacu I was trying to figure out what type of network switch he was going to talk about that clicked...
Denshi-Oji I've got one. It's a 2-port switch (of sorts) integrated into a big multi-port analog video switcher. The whole box works through relays, so instead of both ports being active, a button has to be pressed to switch between them, emitting a click in the process.
its crazy how this guy manages to keep my attention with some of the most mundane video topics such as light switches, toasters, and ac units.
What is a switch?
Well, back in the day when I was actin' up, Grandma would tell me to go outside and pull a swit-
"No."
A miserable little pile of secrets?
Don’t pick the small one
Thing goodness he didn't mention them. I never got one myself, although I do joke about how kids today want the Switch. YIKES!!!
I am familiar with those kind of switches. I learned the hard way.
I don't know if it's the content or just the style of presentation, but your videos consistently calm me and set things right during what has become a tough time.
Thank you.

Aaaaaaa I see what you did there
A 15 minute video from TC answering his own question in the "US homes have 240V" video asking why British & Australian mains outlets have switches on them
*chef's kiss*
I think that the toaster needs to make a cameo appearance in each video. Kind of like Hitchcock in his films...
Or Quentin Tarantino, or Taika Waititi, or Peter Jackson..... etc.
Raise your glasses for a toast to the toaster! 🥂
Matt Burwick : I anticipate an episode on smoke detectors very soon
As an englishman, I appreciate the plug love!
actually that sounds pretty wrong
sounds very english, tbh. Would you like that in large, or extra large?
Tom Scott did a whole video on why UK plugs are best
@@Nickelodeon81 I wish we had them here in the us.
@@IrvingIV The US has a lot going for it, but plugs are not one. I was watching this and thinking that the idea of being able of see sparks when you unplug a device is weird, especially since it's only ~120v rather than ~240v
Honestly, having grown up traveling and using various plugs:
British plugs aren't as safe as you think they are. They conveniently accept screwdrivers and European-style plugs quite easily, leaving large open areas. They are robust - but for most practical purposes the European-style plugs have most of the advantages without the disadvantages.
US's plugs just suck though.
Buckling springs deliver excellent clicks in every scenario.
It's also worth checking out Big Clive's videos on circuit breakers to see how extra beefy switches work.
"buckling springs" mmmmh Model M Keyboard.
@@lazymass And then you have single pole/single throw, double pole/single throw, double pole/double throw switches. What he was showing was a single pole/single throw switch, which is the simple on/off switch in 98% of your house. But if you have a stairway or hallway, or a light by the backdoor that you want to control from the garage, then you need a 3-way switch. That's the one with 3 terminals and no on/off marking on it, because it is only on or off in relation to the position of another 3-way. Also if you only have a 3-way it can also be used as a simple on/off, just use only 2 of the 3 terminals. Now what if you have a room or stairway with over 2 entrances? The 4-way switch, with 4 terminals comes to the rescue. 2 3-way switches are used, and every added doorway gets a 4-way.
"And completely safely" *shows UK plug*
As a brit, tearing up in Tom Scott inspired tears, this is good.
I appreciate that endorsement of UK plugs and sockets.
If you want to simulate those ugly, bulky, huge plugs favored in the UK and Australia, just glue a huge thick piece of plastic to all your plugs :) Of course keep in mind that we have huge plugs on 240 volt stuff also but our normal sockets are 110-120VAC, so roughly half the voltage of UK power.
@@MrWildbill UK plugs being safer has little to do with their physical size, nor should their size factor in that much in this design problem. I don't understand the point of your comment.
@@manoerinafanchannel3196 The type G plug shown in this video was introduced in the 1940s. Before that (and still in many cases) the UK used type C and D plugs which really aren't any different as far as safety from the type A and B plugs used in North America.
Being able to ignore backwards-compatibility concerns is one advantage of having your infrastructure devastated in a war I suppose.
@@VitalVampyr is there any reason American plugs couldn't be halfway covered in insulation like the Europlug? That would make them much more safer imo
@@theodiscusgaming3909 The prongs aren't quite as long I think. A larger contact surface also makes it safer to draw more current.
The casings on North American plugs generally have some affordances to keep the grip from slipping towards the prongs that Europlug casings generally lack, that and the fact that North American circuits are only 100V-120V makes them about as safe. At least in the eyes of regulatory bodies they're safe enough.
Alec can make even a light switch interesting. This guy has magic, loving his channel more and more.

4:17 "Everything conducts electricity when you try hard enough" (Shows a lightning strike)
Man, a couple years ago I was working for a company that builds lighting protection systems, and it was so fascinating to learn about this kind of stuff that I didn't know that much about as a kid.
When lightning hits something, all that electricity WILL find its way to the ground, and it doesn't much care about what kind of material it is. I was looking at photos where unprotected buildings got hit, and there were freaking BRICK WALLS that were ripped apart from the strike, and I began to realize that fundamental truth of electricity that, yes, with enough of it, you can make it travel through ANYTHING.
That is scary. But also amazing.
Yeah its realy amazing That The same ENERGY is stored in every existing matter and so will travel through it if forced enough.
Its really baffeling actually how everything is setup in this univers.... Never stops to amaze me
Even through a vacuum, as shown by the existence of CRT screens and ARC Lights.
Well sort of its not really going through the brick more that it breaks down the molecules and atoms.
Yes it goes through the brick if you look at it, but rather is jumps from the water inside the bricks or anything that is in the brick itself (glass pieces for example) At that moment the brick also breaks because dielectric breakdown happens, which means the electric field exceeds the breakdown voltage. Breakdown voltage is where an insulator basically has its molecules crack under the voltage. Everything thing in the world has a different limit (air for example has 3Kv/mm limit)
So what basically happens is that lightning happens and it starts to break everything on its path. It will still find the easiest way. But everything that does breakdown turns to plasma. Which is why the brick breaks down. This is because the voltage field is too high (which in lightning is seriously high) and it manages to make a jump with an arc and that arc turns everything in the path to plasma.
Lightning can also happen without ever reaching the earth (sometims going kilometers across clouds), this means it isn't able to break down the air under the cloud enough to reach the earth.
In short insulators have a lot of electrons close to the atoms this makes it near impossible for current to flow. Air for example can withstand 3000 Volt every millimeter until it breaks down) If the electrical field goes over the voltage limit, suddenly it manages to grab those electrons and bumps them into atoms etc, which ionizes the atoms and you can charge them.
But thats only because the voltage was higher then the materials could handle in the bricks (which isnt much). Lightning has around 1billion volts. this means that you need to have an insulator that can withstand 1 billion volts. A perfect vaccum for example will never have lightning go through it (perfect vaccum has nothing to carry it) Diamond for example has 2 million volts dielectric strength per meter. So 500 meter of diamond would withstand a lightning blast and it would nothing.
@@PhoenixNL72-DEGA- No electricity will never go through a real vacuum, in a real vacuum there is nothing to carry electrons around so there is nothing to charge. Crt screens and arc lights do not have real vacuum. CRT screens have 0.01 pascal or 0.01 millibar. So not real vacuum meaning there are still electrons in the near vacuum (otherwise you would be able to see light) Same for the ARC light which contains gas to make the arc. Again if you have true vacuum you wouldn't been able to push electricity through because there is nothing to push it.
One more detail: the contacts in switches are made of a material that resists damage from arcing (unlike the brass or nickel plating of a plug and receptacle). One common material is phosphor bronze.
