From http://www.scescape.net/~woods/elements/ruthenium.html

"The metal is one of the most effective hardeners for platinum
and
palladium, and is alloyed with these metals to make electrical
contacts
for
severe wear resistance."

The extreme hardness of these contacts means that since perfect
flatness
cannot be achieved in relay contacts, such contact is limted to
a
discrete
number of points.

Really? How hard is extreme hardness? Ever occur to you the
harder
the
contact the smoother it can be polished? Which factor takes
precedence
in
determining contact resistance, smoothness or malleability?

Failure to answer the questions noted.

Failure to put the truth ahead of your agenda is also noted.
You have succumbed to the dark side of the game.

ScottW

So answer the questions, already.

First question depends on the shape of the surface.
^^^^^^^^^^.....
^^^^^^^^^^ .....
Wow, look at all those points of contact between those two non-flat
surfaces
which all surfaces are at some microscopic level. How do you deal with
the
fact that no two atoms are in physical contact even in a solid? When
you
get right down to it... solid copper has the same problems you're
trying
to
attribute to relay contacts.

ScottW

That is incorrect, Scott. Solid copper does not exhibit junction
effects.

Actually... it does... just to miniscule to worry about. Kind of like
your ridiculous theories.

Actually, it doesn't, Scott.
