Hi, i tried to search how to make a button on/off to a JAMMA arcade power supply, but just find how to turn a PC arcade on...
Well, i see that there are switches from many sizes ; switches with a tripolar connection to plug into a cable force and a fuse into the circuit. So:
1- what i should know about choosing one switch instead of another when making a circuit?
2- I need more than just a switch, like a fuse, capacitor, resistor, etc?
3- how to make a button on/off to an old jamma arcade using arcade power supply?

My real purpose on knowing that is to take an old plastic saturn case into a supergun and maybe i can use the original power button, but i saw that it had the switch and a capacitor solded into it.

I`m confused ?( ?( ?(
 
The 2 important things about a switch are it's maximum operating voltage and maximum switching current. You will switch the main voltage which is either 240V or 120V AC. Assuming the arcade supply will have some inrush current at powerup, you will need at least a 1 or 2 Amp type. If you need to switch off a crt monitor chassis as well, this will be 6 to 8 Amps. If your Saturn was using an external power adapter or brick, it's buildin power switch might be designed to switch the lower output voltage of that.
Arcade cabinets need to be grounded. They usually use a 3 pin power inlet that accepts a pc style (VDE) cable. It has a buildin switch and fuse and also a buildin EMI filter. The fuse is needed as the filter can go bad and cause a short circuit. Normally, there should be a fuse already inside your arcade supply. A well designed arcade supply should have a buildin EMI filter as well. What exactly do you mean with a button on off? If with button, you refer to a "non latching" switch, you will make things more complicated. You could use a staircase lightning system controller. Some of those have on / off functionallity.
 
that`s the button:

under the button, there`s a switch saying 4A/32A250V~ -> 32A is the maximum current,right?
and a capacitor saying CS222M - dunno why that

that`s my arcade power supply:

the fuse says 3A. Since i`m using a CRT modified, i just have to plug it into socket. But if i want to turn it directly from arcade power supply, i couldn use this PSU, right? since the fuse limit is 3A.

searched on google how an EMI filter look like^^. Well, there are some components that remembers it, but sorry, i`m new into arcade and eletronics.

Arcade machines don't run the monitor off of the PSU. The monitor is AC power, the PSU is DC.

In arcade machines the monitors are often plugged into a socket within the cabinet. This isn't always true, but for your situation, given your modified TV already has a plug for the wall, it makes the most sense to just wire up a socket inside the cabinet.

Good old Bob Roberts has a good guide (though perhaps suited to your purposes with the isolation transformer). But the basic premise is there. You would eliminate the isolation transformer, and in its place put a wall socket inside the cabinet, and plug the TV into it.

That guide is really a go-to of mine. I had to visit a 4p Simpsons cab yesterday because the jackass who owned it before my buddy bypassed the isolation transformer. Could have killed someone, and did kill the k7000 (rip)
