  • OT: source for power switches?

    Hi guys,

    I know that my application is off-topic (building a DIY computer case), but it would be useful for people building their own amps too.

    So... I'm looking for a SPST momentary switch, but Radio Shack's selection is disappointing. Ideally I'd like a round black button with a green illuminated power symbol on it. I'd hook up the switch contacts to the power switch jumper leads and the light contacts to the power leads.

    Any suggestions on a source for switches?

      Two questions:
      1. What is a DIY computer case?
      2. Radio Shack still exists?
      Isn't it about time we started answering rhetorical questions?

        1. I'm building a custom case for my PC. Rather than buying an off-the-shelf unit (eg Lian Li, Raven, Silverstone, etc.), I'm building my own. The case is the part that houses the motherboard, cpu, drives, PSU, etc.
        It ranges from the mundane:

        2. Yes, actually.

          http://www.mouser.com/ and http://www.digikey.com/ both carry a ludicrous number of switches in every configuration you could imagine.

            I got some switches and LEDs from www.moddiy.com for my custom PC panel. I used the bare microswitches, and diy'd some wooden pushbuttons to go in front of them (buttons inspired by those on Matthias Wandel's wooden computer case...https://www.woodgears.ca/computer_case/index.html )

            Another option would be to rip them out of a case someone is discarding.

            I love DIY cases. A friend of mine has his HTPC installed in an old wooden bread box found at the curb one day. Nobody guesses there's a computer inside.

              That's what I thought you meant. I really wanted to build one of those, once upon a time (In fact, I may have saved those very screenshots). Now I just use whatever off-lease Dell or Lenovo I come across for cheap and/or free. Sometimes I lament for a more interesting form factor, but it's hard to deny the price, and the cases and cooling are usually pretty well engineered.

                These seem like a pretty sweet custom pc enclosures / desks.

                  I don't even know what half the stuff in those desks are!

                  Wow.....

                  It does remind me of a complex xover and wanting to show it off though!
                  I have respect for that!

                    I was going to post a WIP pic, but every time I tried to upload it, it wouldn't work. I think I found an acceptable power switch, but I'm having trouble telling if it'll work:
                    http://www.amazon.com/gp/product/B01...=A7LLRK3RFF6PD

                    I wouldn't have any issues adapting an existing pair of power switch (and LED) wires to it, but I'm just not sure if it's the right type.

                      What you have linked is a momentary power switch. You can use this to trigger a relay for power on, but to actually provide the 'on' function you need a secondary device like the relay.

                        Those are nuts. Amazing, but nuts.

                          The actual power switch used in ATX systems is normally a tiny momentary contact push button switch, which is connected to the motherboard front panel header via a tiny two-pin connector. When the button is pushed, the motherboard then grounds the PS_ON signal in the main 20/24-pin power connector, causing the power supply to turn on.

                            Yep- you have the correct type of switch.

                              Yeh, totally overkill putting the water blocks on every hard-drive and component in the system but pleasing to look at. I want to do a watercooled pc setup in the next coming months. I'm wondering do I buy a case for $100-150 or do I build a desk/case like this for a similar price!
