This is sometimes problematic when dealing with high currents, as even a
slightly higher resistance in one of the contact pairs will cause more
current to flow through the others.
As a ROUGH rule of thumb, I overshoot by 50% or so. That is, if I feel
that 5 amps is worst case and the contacts are only good for 2 amps, I
use four, for a "theoretical" total of 8 amps. I just mentally derate
the 8 amps to 5.
