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?

12:23 Probably not. They are more expensive so they usually just cheap out and use a normal relay. Never seen one with a latching relay.

Oh yes, the house where I grew up had those hard-clacky switches. Never did care for them. My aunt and uncle had a house with silent switches. I think they used mercury.

1. In an office environment, using a fidget clicker can certainly make sparks fly. 2. The question of how to avoid sparks when turning things on and off is a complex and interesting one. One thing you might want to discuss in another video is how reactive loads affect this, and also how smart outlets could help with this. 3. When I was growing up, we had an electric range and, as you might expect, it was connected to a 3-wire, 220 V line. It had several discrete levels of heat, with click stops. I knew it had to do with having two different rings on each burner, and connecting each to either both wires, one wire, or none. Later, most ranges I encountered had continuously varying controls. I always wondered how that was done. To the best of my knowledge this is done with SCRs, which became available, I suppose, around the Sixties. 4. BTW I wonder how they handled burner control in the UK and some other places before SCRs, where AFAIK it's all just 2-wire, 220 volt service in residences (but 3-phase in some industrial cases).

The humble switch.... much more than meets the eye! The simplest and quickest way to de-bounce a switch, is to place a capacitor across its contacts. A better way is to implement a Schmitt Trigger circuit, which latches the change to the output on first contact, eliminating all that make-and-break action of an analogue switch.

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.

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.

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

Toaster! About time one was mentioned again. :-) 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.
