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