Toggle Switch

[Sharpie555]

Has anyone ever tried to replace the power button on their pc with a switch like the one here: http://cgi.ebay.com/Sub-Min-DPDT-C-Off-Toggle-Switch-ON-OFF-ON-SM203_W0QQitemZ190108541655QQihZ009QQcategoryZ1164 4QQrdZ1QQcmdZViewItem

If so did it work, or would it be difficult?

It wouldn't be very difficult to replace the power button with such a switch, but that is not the correct type of switch for a PC power or reset. With that switch you have double pole double throw and they make a point to put in red bold type "does not spring back to center" (off position). For a PC power or reset button you need a momentary switch that will only close the circuit while you press it and then open the circuit when you release which that switch does not. If you leave the power switch in the on position, your PSU will power back off in 6 seconds.

Thanks for the help, would this switch work then?

Yes, that one would work.

[intergalacticman]

yeah, actually i did, i was at ace, and i saw its potential for an industrial themed mod, and although the feature when windows does the all the "windows is shutting down" stuff doesnt work, it just shuts off the power

I was wondering the same thing. I have this switch. Anyone know if it will need a resistor or how to Hook it up?

Do you just run the regular wires to the mobo? And thats all?

[Bucko]

Does that switch spring back to normal? Or when you flick it does it stay in the other position?

If it springs back and returns to normal it will be fine to use. Just hook up the the two wires that are going to you current power switch to it.

If the switch stays over when you flick it on rather than springing back, I wouldn't use it. If you hook it up it and turn it on, the switch will act the same as when you hold in the power switch on your PC. ie: It will shut itself back down.

Yea it just goes one way and the other. . I need the momentary kind then huh?

[Aero]

yep.


Momentary switch = good

All else= Evil


I suppose you could disassemble the switch and place a small compression spring in there so it will just activate for a short amount of time and the deactivate well within 6 seconds.

i just ripped off the old button and soldered on the switch, but it is on an older p3 computer where the switch directly connects to the PSU. i dont know about newer psu's

You can use those switches to turn on fans and lights and stuff though.

On the topic of switches . . .

With this arrangement of wires would I be able to turn on two cold cathodes with one switch? Or would it short or something?

Also, would the momentary switch used for http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=95&products_id=3651 be easily replaced? (look at the pictures)

Thanks

Ookazoo, here's the diagram to wire 2 cathodes to one switch.

The blue tubes are the CCFLs and the I boxes are their inverters.

Thanks, that looks good.

You can use non-momentary switches to turn on your computer. push it up, computer turns on, push it down, computer stays on. Just do that kind of quickly, and no worries.

You beat me... But yeah, that's what I was going to say. Whether or not you want to do that every time your computer starts is up to you, but it's better than nothing.

To turn on my computer is more complex than pushing a button, though.

I type in a 5-letter password then hit enter, then it turns on.

:banana:

[Ookazoo]

how did you do that?

[Redundant]

Did you put a password on the BIOS?

[intergalacticman]

wait how do you put it in the bios if it isnt on yet???

[Omega]

BIOS option. "Power-on by keyboard", setting is "Password".

The button won't turn the computer on. People try that, and I laugh, then turn it on. =D

nice
