Wiring a button to the PC start up button

Yes, thats the way the circuit I envisioned would work, just with this type of switch, it looks and feels like the original power switch in the back of the arcade cabs.

Okay, ive got it now.

How about a pc set for immediate shutdown, with a Momentary toggle switch wired to the power on/off leads on the pc, put in place of a direct 110 on/off switch like the original cabinets came with?

so whenever you bump this toggle switch, it fakes itself well enough to pass for the original switch on the cabinet? that will eliminate the whole entire capacitors and other extra parts and simplify things enough where it would in fact satisfy me, but mabeye not other people who still want to hear an audible click.

DaOld Man:

Yeah that would work.

Flip The Switch:

Jobs done, just followed the wires from the power button, which were both white, going to the jumpers, just cut the white wires (still attached to the jumpers) and crimped on 2 lugs and ran them to a micro switch, just need to get a button now :D

do what i did and you wont have any problems. all you need is soldering iron and small pair of pliers.

(1) locate the original dell power button .
(2) now look at the back of it and you will see where the pins stick out . ( should be 4 of them )
(3) then take your pliers and start touching 2 pins at the same time to find the circuit ( pc will switch on )
(4) take a note of the pins which jumped started the pc and prepare a soldering iron.

now solder the ends of the new wires first and then continue to solder the wires to the pins.
this is easy to do provided you applied solder to the new wire first . and it doesnt matter what colour wire
connects to which pin ( positive or negative ) as all your trying to do is make a connection. happy gaming :)

The only reason in the world i could think of why a power button would have 4 wires on it would be that two of them are for a light and the other two are for the on/off signal.

best thing to do if you dont know is to start poking at pairs with a DMM until you find the wires for the light. Their should be a constant voltage of either 12v or 5v detected there. any common sence conclusion would be that the black wires would be ground although not always.

so what im saying is that the other wire connected to ground should be your soft on/off switch.

my other question would be do you have a 12v mini lamp in a socket with connector probes at the other end? if not, you need to make one.

a light that does not light up wont damage anything. But if you take a guess and connect that 12v light source to the soft on/off you stand a good chance of taking out that feature on your mobo.

i never said 4 wires, i said 4 pins .
the pins on the back of the switch " plug " into the prop board and they are used as a method to attach the button to the board
as well as acting as a method to switch on the pc. although only 3 pins are attached to circuitry on the board , only 2 pins are needed
to allow it to switch on and off.

while there are 2 leds on the board ( power and hdd activity ) , they are not located on the switch itself .
