I'm wondering if I can load a LED with a 2.2K resistor tied +5V and other side to a SW & Arduino?

Opposite side of SW to GND.

Will this set pp damage my MEGA 2560?

I can save a lot of Arduino pins doing things this way.

Thanks

Hi Harry,

At last I have added the page with explanation of the position indication type you have suggested.

Here it is (it has no link on the website menu yet):
