Help Measure

[AtomSoft]

Hey guys i have this:
Digi-Key - SW1019-ND (Manufacturer - B3DA-0010-A)

Here is relevant image from PDF with info needed to help...

From TOP MOST LEFT HAND SIDE BUTTON... how many MM is it to center of next button?

If it says 3 buttons is 21MM then i just divide by 3 right? I get 7...

So each should be 7mm apart from left to right correct? How come it seems to be 7mm apart from top to bottom not left to right

heh i tried the distance between 2 holes on sheet which is 10mm and seems perfect... so 10 from LEFT TO RIGHT and 7 FROM TOP to BOTTOM

hi atom,
Its the old case of how many gaps between 3 telegraph poles.
Count the gaps, not the poles.
