Touch-type actuation devices have become increasingly popular in a wide variety of products because they are easy to use, easy to clean, and they provide environmental sealing and a broader range of aesthetic options. Resistive touch screens and glass-front capacitance controls have become more extensively used in recent years, and are well-suited for many applications. But there are many situations where rough handling, extreme environments, or the potential for vandalism demand something more rugged and resistant to abuse. Piezoelectric switches are often used in these cases, but they, too, have some limitations.
