I am going to use the SMPS-86 to power my Modulus-86. My plan is to reuse a case I made for an ACA. It has a front mounted SPST on-off style switch for power on. I would like to keep the switch as the power on for the Modulus-86. Is there a ready made way to hook this up?

There is a spot on the SMPS to mount a RA switch. Just wire the switch you have externally to the PCB pads.

The switch pad is setup for a dpdt switch unless I am missing something.

Yes. Just jumper the Neutral across the switch leads on the PCB and switch the Hot if your chassis switch is SPST.

I just listed a Power 86 PCB, parts kit and AS-2222 transformer in the Swap Meet if someone wants to save a few bucks on a build!
