    I used to press switches and jam them halfway with my hand to kind of dim the lights as a kid. I know now it was really dangerous haha

            A switch is under greater load dis connecting a load.

              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.

                                            Great to know that our switches in Switzerland are perfect then. It's impossible to cause arcs with those, though they are also totally over engineered.

                                                          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.

                                                            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 =)

                                                              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.
