Capacitive Sensing Touch PET Membrane Switch With 3M468
Capacitive sensing touch membrane switch does not need to directly contact from body. The switch can be pressed by glove. So this feature can eliminate potential safety hazard and is not affected by weather, dry and wet resistance change of human body. It is much more convenient to use. Little abrasion and infinite life reduce maintenance costs. Capacitive sensing touch switch can also activate under the insulation shell more than 20 mm (glass, plastic, etc.), with effienct reaction to the finger. Besides, the sensitivity, stability and reliability of the product will work well in the changing envirenment. As waterproof and strong anti-jamming capability, the functuions will be stable as the long term working.
Single chip, few peripheral parts, simple circuits, and no oscillation circuit, easy for production.It can get satisfactory effect, only according to the artwork.If a variety of special interfaces touch-key induction ICs, single button interface, and a variety of special requirements are needed, it's unnecessary to modify the product MCU master control program. To implement with the single chip microcomputer interface touch control applications is very easy.
