I used this switch for that exact purpose...
Any switch in line with the ACC line to the PSU will work though.
In the middle of sorting my car PC out and i have been trying to get some information about a power switch that i can have that will allow me to leave the PC off if im only doing a short journey.
So if its set to ON PC will power up when turning over the car, if its OFF it wont
Ive read a few posts on the forums, and i think im right in that i would install a switch inline on the ACC line, is this correct?
Also, if so what kinda switch do i need? Anything in particular or just an ordinary onn/off switch?
That's the style I actually googled, spooky! With the 4 pins at the bottom is it easy to wire?
I have no auto electrical expertese at all! Seeing there are 4 pins and only 2 wires (from cutting the wire) I'm confused already
lights up when on rather than constantly. Use a higher ohm one if you don't want it as bright.
Ah ok, that makes sense. If for whatever reason didnt want or need a visual led i could just ignore the bottom two?
Found one on eBay that has only 3 PINs, GND (obvious where that goes) and then PWR and ACC.
Wiring that in would it be PWR to the ACC line (as thats where it will get the power) and then the ACC pin connects to the M2?
Or have i totally got no clue what im talking about and its the other way round?
Why ebay though with all the online parts stores? That should be correct, yes. Assuming SPST, worst that will happen is the LED will be on constantly rather than only when your PSU is getting the ACC feed should the acc/pwr lines be reversed. Do you have a link?
the three pins are the same concept of the switch above it just uses the same ground there for no need for the forth pin one is positive one is ground and one is acc which is for the led if you dont want the led just hook up the to powers and not the ground.
