CHS is designed as as invisible/hidden switch that is installed easily and efficiently (by adhesive sticking) under the user interfaces front panel (with material including non-conductive ones) without any openings needed. It can be programmed to operate without users touching it. CHS stands for Capacitive Hidden Switch. Capacitive techniques makes all the advantages possible: 1. design freedom on the interface panel. Applicaion device designers has no need to concern about openings for installation 2. can be programmed to touch-less operation for hygienic purpose 3. easy/fast installation by adhesive sticking on the back of the interface panels 4. interface panels are easy to clean 5. water insensitive 6. wide operating temperature 7. 3 variances available. i. without illumination version with <6mm mounting depth. ii. with optical feedback by various colors and voltages of RGB lighting iii. potted version with lighting for demanding use in harsh environment Applications * Invisible switch ¨Cdesign units * Medical/Laboratory/Food industry products * => Hygienic -no gaps in which bacteria can nestle Advantage * Wiping and water * No uncontrolled triggering of the switch by water on the surface or wiping over the surface * Safe & easy installation * Competitive pricing * Completely potted version * + 85¡ãC environment temperature * Illumination: various colors & voltages.
