  • Fortunately, the dimensional drawings are correct you have just read them incorrectly. True, the space between buttons adds up as 4x7=28 and the size of the top of the buttons is 4x15=60 to total 88mm. However you didn’t look properly as you missed the slant at the edge of each button, 1.5mm per side. 2 per button and 4 buttons makes up your missing 12 mm.
    Hope this Helps.
