Electromechanical devices, including switches, keypads, keyboards, pointing devices and other elements such as indicators and alarms, are critical aspects of the human machine interface (HMI) for controlling equipment and systems. HMI Component technology has undergone major changes over the years to serve the increasingly specialized needs of industrial, transportation, telecommunications, audio/visual, public access/security and lifting/moving applications.

Designers today face a truly astonishing range of choices in electromechanical components that encompass not only the type of device, electrical specifications, environmental sealing, and mounting and termination styles, but also ergonomic considerations such as configuration, size, illumination and tactile feel.

This white paper discusses how these electromechanical devices work and how they can help users meet their requirements when incorporating them in advanced HMI systems.
