On/Off switch location

[snes4ever]

I know this is a weak question but its driving me crazy, I am working on the original snes and I cant find the on off button.

I have already taken it apart and relocated the card slot, It wont work, I think this is bacause somwhere I pulled my modified switch off(i put in a switch instead of the constantly on method), now I dont know where it is supposed to be inputed? Help. i can only find the reset switch.

It's next to the 7805, I believe.
