Power button orientation?

I've gone to the trouble to replace the flex strip PMV cable and I'm up to the part where I place the power button back in contact with the flex strip.

However, because of either the angle of the button and that metal ring attached to the power button, I can't remember which goes where?

The ring can swing freely on one side, but the other side movement is limited (which of these 2 sides orients upward? Does the flex ribbon sit under or over this ring?

It seems when I try to screw the plate back on, with the metal ring swung dowward, there's not enough room. But at the same time, I can't seem do screw the plate back on if the ring is swung upwards.

I hope this makes sense.

Thanks
