The Top Ten Off Switches 245

Posted by CmdrTaco
from the no-i-can't-make-this-up dept.
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.""

    Toggle switches rule [amazon.com] period. Batman used toggle switches in the batmobile. Fighter pilots flick toggle switches in the movies before they blow up bad guys. The Millenium Falcon probably had a couple hundred thousand toggle switches. Cool electric guitars? They've got a toggle switch. When I built my first model rocket launcher - I think it had 3 toggle switches. A good solid 'click' of the old toggle is just the thing - all other switches pale in comparison. Even the big red button.

      The only thing better than a regular toggle switch is a toggle switch with a flip-up protective cover. It says "You had better be damn sure of what you're doing before you toggle me. You need executive orders to flip me, and those orders must have been confirmed with the one-time codeword. Lives are at stake, here."

      I saw a documentary or something with Harrison Ford talking about how the original star wars budget precluded the use of functional toggle switches in the millennium falcon. Apparently, rather than splurge on good toggle switches, they somehow managed to buy discounted defective spring-less toggles.

      #8 on the list was the Emergency Shutdown.

      I used to work with a guy that had been in the Air Force in Vietnam working in some type of data center. He told me a story about an event that happened one night that forced an emergency shutdown. If I remember correctly, a water pipe burst and the data center was being flooded. As he was on duty that night, he went around shutting down all of the equipment. One machine, in particular, had an "Emergency Shutdown" lever. In training, he was told that he would never need to use it, but it was there. This seemed like an emergency, so he pulled the lever. What he didn't know was that it released a weighted blade that fell down through the backplane severing every wire in its path, essentially destroying the machine.

      The aftermath was, a couple of Air Force techs spending weeks soldering the thing back together again, and he got every s#^t job that came up for the remainder of his tour.

        The power failed - if your backup generator or battery system isn't properly maintained, you won't have to worry about shutting off a room full of equipment. Personally, since I run nothing critical on my machines, let the power fail. There are no settings to restore when they're all network-booted anyways.

    ...we will forget the off switch. I understand the need for managed shutdown, but there was always something satisfying about activating a solid on/off switch to cut all power to the system. The switch always did the same thing. It was dependable. Sometimes, if it was spring-loaded, it even had a satisfying "chunk" noise to tell you with extreme prejudice, this machine is OFF. Industrial!
