The Top Ten Off Switches

Dan Jimbokla submitted a story that normally i would pass over, but I actually oddly enjoyed it. "CNET.co.uk has a truly funny and read-worthy article up about the top ten off switches. One of my favorite switches from the piece is #4 — The illuminated toggle switch: "This switch isn't designed for high-drain uses, typically it can only provide a maximum of 20 amps at 12 volts. That will make it suitable for a number of exciting uses though, and what it lacks in power handling, it makes up for in practicality. This switch will illuminate when the device it controls is turned on, and go off when the device is deactivated. This is logical and practical, and that has earned this switch a place in our hearts. What's more, it's far from expensive and there are even a choice of colors.""

    If so, the vacuum relay. Can switch large amounts of power and comes in a relatively small package. These are very fast as well. High power radio transmitting systems use them

      You mean the thyratron. Because at the heart of every high energy physics experiment or giant pulsed laser is a thyratron (or a thyristor, the solid state equivalent).

    Also remember to wire your emergency 'off' switches as normally closed, so if the switch fails the equipment will stop. Nothing worse that going to switch off a 30HP motor that your tie is stuck in and the damn switch isn't working.

    You're forgetting... the original Enterprise used toggle switches, especially in Engineering. You can bet Scotty wouldn't trust just any old switch to fiddle with antimatter.

    Or a piece of paper taped over it Apollo 13 style - my all time favourite protective cover. I often wonder whether that actually happened or whether it was artistic license.

    It happened. As told in the book, before the time came to do the jettison, Swigert had nightmares that he'd flipped the wrong switch and watched his crewmates drift away. He made the sign (saying NO) as one more check in the system. I seem to recall that he asked one of the guys to check him on it, too.

    The mnemonic is an "open" ( O ) versus "closed" ( | ) electrical circuit. A circle could be seen as open, as the circuit appears to "break" as it passes through the center of the O. Meanwhile a closed circuit passes directly through the center of the line, unbroken.

    cnet's talkback feature appears to be broken, so I'll do the thing here:

    Data's off-switch is awesome, but the dude's got it wrong - it isn't on his leg, it's in his side above his hip. If I remember right, above his right hip.
