Power switch circuit

[Ghost]

Indeed!

I had though perhaps if the switch could be partially slid it could be clicked into place to make the shutdown contact and then slid to the middle to avoid a hard shut down and avoid the on switch portion of contact.

Yes, that would probably work, but it would hardly be ideal having to fiddle with the switch to find that middle position. Better perhaps to replace the original switch with a similarly sized and shaped momentary version...
