The IC’s project sense fields (from conductive sensors) up through dielectric, translucent material which can be up to 10mm thick. The use of capacitive switching enables designers to backlight the switch positions while allowing the use of clear material to be used in capacitive touch screen assembly. The use of such materials means that the switch is easily cleaned and impervious to accidental liquid ingression.
Capacitive sensors can be designed to take into account many conditions before the switch is activated by continuous self calibration. This is achieved by changing the duration of the capacitive charge burst and allows the product to be used in any condition.
A complete lack of moving parts means that mechanical failure is eliminated and sense fields can be predicted through dielectric material enabling vandal resistant panels to be easily produced. The operational sensitivity of the switch can be easily adjusted to overcome various environmental conditions.
