Time for a comedy break! This is all rhetorical non sense so bear with me....
The pics are of a standard design factor for some kind of normal thing folks want. Ok. It has 3 relays 2 5 ohm joules/10watt ohm resistors, a fuse, a transformer a couple of dip chips and 3 ports for what ever it powers and switches. One of the chip is tape labels with SG0008J. And it's also got a beeper on it and the complete setup is switched, through the fuse. I have attached a standard two prong plug to board, which has a switch built into the line The ports are as follows.
PA1 PA2 PA3, 1 is 4 pin, 3 is 3 pin, and 2 is 6 pin.
The board is putting out a nominal 6.5 v and the relays are tv-5, SRU-5-112L 240v source and 24v signal at 10amps.

I want to build functional switches to trip the individual relays, and use it as a switched bench top PSU, how can someone find out the pin outs on the ports, so they can build the triggers?

Please note... I can't remember what this was in, or where I got it!

That looks like a washing machine control board.

I want to build functional switches to trip the individual relays,
Remove the relays and wire directly to the coils, using the contacts how ever you want.
and use it as a switched bench top PSU
The power supply components are the transformer (top of the board) and the three items to its right, a bridge rectifier, smoothing capacitor and U1. Remove them from the board and wire them up accordingly.
