Here is what I'm doing. I've got a 12v power supply that I'm connecting to my board. I'm trying to set it up so that I can leave the power supply plugged in, but only enable the power when I press on my SPST button. Please see the diagram below:

Currently I'm getting 12v even when my spst is "Off" . Thanks.
edit: I just noticed that if you don't view the diagram in full size it looks kind of weird.
