A new spy novel title? Unless you post a quote of what you are referring
to, it's hard to tell.

The wiper is the metal bit wot touches the resistance element.
There are actually two sliding contacts involved in most (not all)
pots, a sliding low-resistance connnection to the moving contact and
the wiper contact to the element. Good quality pots and trimpots are
actually extremely reliable in most situations-- billions of them are
made every year. In production situations it's nice to avoid the
labo[u]r of adjusting them, but even that is a mixed blessing as much
of the adjustment process can be an essential part of the test
procedure.
