Wiring NAC PSU's Rocker SW

[erzane]

Pls can you confirm if my rocker SW wiring is correct? The former SW do have only 2 pins but my replacement SW do have four. Formerly, the SW was connected to pin 1 & pin 2 but I don't remember which wire was hooked to pin1 and which one to pin 2.

Also, my Fuse is 250V / 4A but the manual suggests 125V/4A. Can I use both? What happens if I use a 125V/3A?

Thank you!

The original is single pole, your replacement is double pole. It doesn't matter.

Formerly, the SW was connected to pin 1 & pin 2 but I don't remember which wire was hooked to pin1 and which one to pin 2.

Doesn't matter. The switch is just opening the connection.

What happens if I use a 125V/3A?

It's going to be fine. As long as you're powering regular boards and not plugging a computer in to the AC outputs of the PSU, it's not going to blow.

Noticed. Thank you!

Regarding the Fuse : Gradius IV Fukkatsu, VF3, SW Trilogy or Cave SH3 are considered as ok?

VF3 and SW Trilogy need a different power supply, but otherwise, yes.

I see. So I can also use a 125V 5A or even a 125V 10A to have more secure?

Fuses are there for overcurrent protection, like if there was a short. You don't want to go too high otherwise it defeats the purpose of having one.
