Evinrude/OMC neutral safety switch at Radio Shack?

[Hannibal]

Trying to replace the neutral safety switch and after reading numerous posts (here and elsewhere) - I can't find a part #. I've looked at blown up diagrams showing part #'s and can't find anything. It's in an OMC throttle control and while it's discussed in numerous places, nothing gives me a part #.

I did read several times that it was a micro-switch and you could get one at Radio Shack. Has anyone done that? Can someone point me in the right direction?
