  • Momentary Switch install

    Ok I did a search on this but there alot of of differences on where this installs it seams. And I am just not fully understanding it.
    I am running a M1-ATX 90w and I would like to add a Momentary Switch for the times to where I don't want the PC to power on.
    Do I install the Momentary Switch on the 12v line from the battery?
    Or does it go on the acc line?
    Or do I just connect it to J8 on the M1-ATX

    Im so confused

    Thanks

      If you want something to *stop* your PC being turned on by ignition you will need a push to make/break switch or a rocker switch, not a momentary.

      The easiest way to do it is to put the switch somewhere along the line from the +12v line from the car battery to the M1-ATX, leave it closed and it works as normal open the switch and when you start the car your pc will stay offline.

        Well there is a jumper on the M1-ATX (I think it's J8) and we can hook up a switch there so I think it would be a better way !

        Anyway, get some wires and a switch (they are like 50¢) and test it That's what I planned to do but right now not a lot of times lol

            Actually, the best way to keep your computer from booting is to use the feature built into the M1-ATX, if it has one. I am not very familiar with the M1-ATX< but if you look through the manuel, and see what it says, you can figure it out. Now, if by chance you have no desire to then the next best way to do it is to put an on-off switch in the accessory line of the power supply, AND NOT THE BATTERY LINE. This is simply because, the PS takes about 10 amps or more of power through the battery line, 10 amps is quite allot, and a switch ith that current rating will be big, and bulky. Also, you will have to lengthen the high power wires to get to the switch, and back to the PS, which increases the power loss over the wire. The accessory wire probably carries less then an amp, and most likely about 200 or so milliamps. No need for a high power switch, and extending that wire will not seriously hamper the current carrying capacity. Also, if you take the power from the fuse box, it is probably pretty close to where you are mounting the switch, although not necessarily.

            You could also use a relay, but since you asked the question, I would assume there is no reason to increase the complexity of this.

              If in doubt, experiment. Otherwise, say go with the switch on the ACC line.

              I' confused, though. Shouldn't it be a SPDT switch. It's that an ON-OFF swtch. DPDT is ON-OFF-ON. The SPST, I believe, it the momentary but what purpose would it serve? You would have to keep the switch held down in order to have the power flow down the ACC line. Go with the SPDT switch. (If I'm correct on this.)

                You don't want a momentary switch. You only want a momentary switch if you're going to hook it up to the motherboard as a power switch. For the power line to the carputer, you're going to want a non-momentary Single Pole, Single Throw (SPST) switch.

                  SPDT refers to the way the switch works. You can buy this switch as a momentary or permanant (like a light switch). The SP says that this switch is a Single Pole which refers to the set of contacts the switch can work with -in this case a single one. DT refers to double throw, which means there are two positions the switch can be set to.

                    Yeah. I knew what I was trying to think of but it just didn't work out right.
                    Here's a really good site that shows the differencs between switches. It's got pictures too.

                      I'd like to thank you all for your input.
                      I ended up going to radioshack and buying this switch
                      Switch

                      I plan on installing it on the Acc line, as soon as I get all my other wires run.

                      Again thanks
