Material
Construction:
Elements molded
into a single, integral structure.
Metal cover protects and shields
the internal parts.
Sealing:
synthetic resin containing
non-mercurial fungicide
Since all rheostats/potentiometers
are electro-mechanical devices,
they are subject to mechanical
wear and, therefore, have a finite
life.
