HELP: Turn on the PC with a two-position switch

[Connor]

Hello, as you can imagine, computers are turned on with a button, the problem is that I want to turn on the PC with a key switch, of which I have only seen two positions or ''on/off''. The problem is that if I put one of these, I would have to turn the key twice very quickly for it to turn on and not restart over and over again. Is there any way to prevent this from happening and be able to use a two-position switch like this?

Thank you all!

-Here's a picture of the switch just in case-

Just use one that has a 0-1 return spring, you turn it to 1, release, and the key returns to 0, like in a car.
Maybe it's easier to find one with 3 positions and return, where 0 is the extraction, 1 is the assembled (in your case not activated) and 2 is the actuation.

I remember a guide out there from a long time ago about the same thing, but I can't remember where. :wall:

The problem is that I can't find a switch with a spring, and I've looked pretty hard for it :nono:

Well, I think that in any electronics store you can find a 2-position NO key selector switch with auto return. They are nothing out of the ordinary.

My cousin had a system with a couple of bays in which there was a hard drive in each one (honestly, I don't know very well how the system was mounted, but it smells like prefabricated bays for this cause especially). Both had a key, and turning it, it activated said hard drive and allowed booting from it. Normally, he alternated, never turning on the PC with both activated, but I suppose you can do basically the same thing with a single drive, since if the key is not turned, the disk is not "connected", and therefore when booting it does not detect it (or that is the theory).

In a pinch, if you really can't find it ( Sassin Electric ), let's try this:
You grab a flat ON/OFF switch, and you route the PWR_SW pin (the one that goes from the board to the power button) through it, so that unless you turn the key, the button won't work.

Edit: I understand you have your reasons for making such a modification, but if it's for security, keep in mind that a computer can be opened by removing a couple of screws.

It's so that my brother doesn't use the computer, I thought that I could connect to the cable that goes to the original button so that if the key isn't turned, the circuit won't close, anyway, thank you very much! ;D

You can always twist your brain a bit and mount some kind of "secret" switch inside the box that prevents current from reaching the board, or directly remove the power supply cable
