ElecFlex has been offering top-quality customized capacitive touch keypad for global customers with industry-leading technology and extensive experience in the past decade.
A capacitive touch keypad is an up-to-date electrical switch. It operates as a touch-controlled switch, which detects changes in capacitance to function. It does not require any mechanical components, but detecting the alteration of capacitance and trigger the corresponding action for the specific key or area touched.
The main advantages of capacitive touch keypad include high sensitivity, rapid response, long lifespan, easy cleaning, and excellent waterproof and dustproof performance. All these features enable capacitive touch keypad to surpass conventional keypads in many applications.
How does it work?
Its general working principle is, the controller detects the capacitance between the switch and ground. When a finger or conductor touches the switch, the capacitance between the switch and ground changes. This change will be detected by the controller and the corresponding action will be triggered.
The users may choose the material of the keypad overlay according to their preferences. The common material choices include glass, PMMA, polycarbonate, polyester, metal etc. And, specific textures or coatings can be applied to the material surface to enhance the tactility and accuracy of keys. Furthermore, customized graphic can be printed on the material, which beautifully improve the user interface.
Elecflex's manufacturing capability for capacitive touch keypad
ElecFlex can provide all-in-one capacitive touch keypad which has capacitive sensor IC included, as well as touch overlay. Customers will benefit from easy-to-integrate touch functionality through this turnkey solution. We offer flexible output signal options such as IO, BCD, ADC, I²C, and others, based on customer specifications.
For the overlay of capacitive touch keypad, Elecflex offers glass, PMMA, polycarbonate, metal, polyester and others materials according to customer's needs.
Of course, if the customer has integrated the touch sensor chip on the mainboard, Elecflex can also provide a simplified capacitive touch panel. This structure consists of a touch surface layered over the sensing circuitry (copper or silver-based printed circuit board), transmitting capacitance changes to the touch sensor chip on the mainboard via a standard interface. This type of application is very common in today's market.
Extra Value-added Features in Capacitive Touch Keypad:
In addition to necessary functionality, Elecflex also offers value-added features in capacitive touch keypads, such as backlighting, waterproof, anti-bacterial, dead-front printing.
