    Great to watch a video on clicky switches while repairing a clocky switch.
    To go more into detail: The one on a flashlight that is basically like the one on a ballpen. One of the sheetmetal contacts broke off due to a cheap plastic housing and needed some bending to sit right again.

    I remember back in the sixties there was a type of wall switch that was called a "mercury switch" and it worked completely silent. It had a small glass bulb in it kinda shaped like a tic tac. On one side were the wires that needed to be connected to turn the light on. On the other end, was nothing. Also in the bulb was a blob of free floating mercury. The tic tac was able to be rocked or slanted so that the mercury would either be connecting the wires or on the other end not connecting the wires.

    I wonder if that system arced. I don't even see those sorts of wall switches for sale anymore. There's probably a good reason for that.

    Here's a photo of one I found on Google.

    I like how you says "very a a fe" and show a UK plug.. One thing I find interesting is USA is 110volts UK is 230-250volts lol and heaters here use 3000 Watts not 1500.. There's been few tins I switch something off at the wall and the socket sparks as I forgot to turn it off on the actual device. So even a switch has big sparks as when you plugged out the heater.. Except when you pull a plug you pull away.. When the switch sparks your hand is a till on the switch and BAM you get shocked

    Some of the first light switches used Mercury and wires dangling in them as the contact 'switch', circa 1880.
    As Swan (UK) and Edison (USA) had invented the light bulb but no switches - how to control them? When Lord Armstrong wired his house called Cragside, in Northumbria, UK* he used Hydro Electric power (DC) as the source but had to invent a light switch. His solution was to convert some vases (yes: think flowers + water) to contain mercury and have a wire that made contact into a pool of Mercury to complete the circuit.
    * Cragside is well, well worth a visit if you visiting the North of the UK: it is an amazing Hi-Tech Mansion by Victorian standards with all sorts of innovations such as central heating *_Wow_*, hydraulic lifts, fire alarms, electric lights etc. - Armstrong was the Elon Musk of his day being a Lawyer initially but then specialising in Hydraulics (most famous achievement: London Bridge opening mechanism, see various TV programs). Sadly the vases and light-switch-setup are not on display even as a recreation/replica; they seem lost to history.

    Disclosure: no affiliation to Cragside or its owners The Nation Trust; a paid full price when I visited earlier this summer.

    Because there's nothing out there. It's stupidity. Stupid people mingling with stupid people. Let them stupidify themselves. I've never been bothered with the need to rush out into the night. I hid in bars, because I didn't want to hide in factories. That's all. Sorry for all the millions, but I've never been lonely. I like myself. I'm the best form of entertainment I have.

    I had a light switch go out this weekend and now I know exactly why. This explains everything as it was about to go out and now doesn't make an audible click at all and doesn't function.

    When I was a kid there was a light switch in a storage room in our church - the switch was so "clicky" (and internally must have prevented arcing) that you could toggle it and step away for 1-2 seconds before the light would switch off. Fun was had.

    1. Because there's a spring in there to provide a positive force keeping the switch in either the "on" or "off" position and not in between where it's liable to arc.
    2. Because it makes people happy.

    My guess is the fact that the desired effect from most light stitches is to turn the light on or off as quickly as possible helps with them last a very long time with little chance of failure. I have some LED lights that have a short period of time before they completely turn off. A fraction of a second but I still noticed, and after the switch had been flipped.

  • Lady D

    My light switches are more like buttons (they're still quite clicky tho) that light up when the lights they control are off...how do they work? I assume similarly but still wanna know specifics =)

  • usbcd360
    usbcd360 2 days ago

    In the past, the really clicky ones were intended for non-bedroom spaces, due to their sound. For bedrooms, there were switches with mercury capsules instead, since the mercury would evaporate and recondense, reforming your switch contacts when they got blown away. The new ones are a compromise, since you can't just throw mercury at every switching problem now.
