HUMAN ENGINEERING

Positive confirmation of switch function involves sensory feedback. At Conductive Technologies, this involves the proprietary "Tridome" tactile mechanism. When mounted immediately beneath the key surface, Tridome provides a firm counterpressure assuring activation. The Conductive Technologies Tridome is designed for longer life than standard tactile response systems.

Other ergonomic innovations by Conductive Technologies include embossing of key surfaces, perimeters, logos, legends, and even raised Braille characters to facilitate compliance with laws for the vision impaired. Additionally, Conductive Technologies switches may be curved to conform to cabinetry and hinged to provide multi-level arrays and displays.
