These switches are often used in conjunction with a generator, connecting the generator’s electrical output to the electrical input of the system to be powered (i.e. hospitals, commercial buildings, homes, etc.).

The hardness of electrical contact materials is a critical material property that must be accurately & consistently monitored. This briefing provides an overview of electrical contact hardness.
