Thread: switch option on a M1-ATX

I think they are switch outputs not inputs.

One of them goes to your mainboard on/off push switch for the M1-ATX to send a 'pulse' to turn on/off your mainboard.

The other one in parallel can be used for turning on/off your amps or other electronics I suppose.

Are you thinking off a 'manual override' type on/off switch to turn on/off your M1-ATX?

J6:controls AMP on/off

Thanatos.

thats correct so how do I use this optional switch?

it works in parallel so can I have both connected or is it either or?

The switches you need are like pulse switches, (you don't "switch" them, you just temporarily make a contact, its only closed for as long as your pressing your finger on it). You could have as many switches as you want in parrallel, and they will still work.

Because you don't switch them to ON or OFF, wiring in an extra switch will not/cannot stop your computer from booting.

ahh I get it now.

I've bought a on/off switch now is there any way I can wire this in ?

cheers

What if I put a stich on the ignition feed?

If I have this switched off and turn the car on then it wont start. If I have it switched on and turn the car on it will?

Would that work?

cheers

It will be unpredictable if you turn it on and leave it on. You could try it and play around with the settings in Windows and your bios, but switches are cheap, get a new one.

The M1 will only allow the computer to be switched on (either by pressing a switch or by the M1 "pressing" a switch) if the ignition feed is live.

So wiring in the switch in the normal manner will not allow you to switch the PC on if the car's ignition is off.


What exactly are you trying to achieve with this (or any other) switch?

• Be able to use the PC with engine/ignition off?
• Be able to reboot/turn off PC when engine is running from the drivers seat?
• Stop the PC from booting when starting up the car?
• Something else?
