The negative terminal has TWO pins which are BOTH electrically
connected.

The 10 mm spacing of the 2 pin snap-in is used as the base layout
and a third hole is added.
The third hole is closer to the negative primary hole so that
polarization is always maintained, together with added mechanical
stability.
