The Solid State nature of the circuit makes the life of such a switch virtually infinite. As a result, such keyboards are very much suited for harsh environments, where switch abuse, vandalism, use of dirty hands is a common practice.
Capacitive Switch
Capacitive Type sensor detects the presence of any dielectric material in the proximity of its sensing face. They are used for detecting non metallic objects, liquid level and other sensing application.
