Capacitive touch technology has become the mainstream of touch technology. The buttons can improve the overall appearance of products. Even 20mm of insulating material shell (glass, plastic, etc.) is not a problem for sensing.

The device can accurately detect effective finger touches, ensuring that the product's sensitivity, stability, reliability will not be affected by changes in environmental conditions or long-term use. It also has water resistance and strong anti-interference capabilities.

Compared with traditional membrane switches, capacitive touch membrane switch do not require fingers to directly contact the graphic overlay, which can completely eliminate safety hazards. They can be touched even with gloves, and are not affected by changes in human resistance in dry and humid weather, making them more convenient to use.

There are no mechanical parts, no wear and tear, unlimited lifespan, and reduced maintenance costs. The sensing part can be placed behind any insulating layer, making it easy to create a keyboard that is sealed from the surrounding environment.

Patterns on graphic overlays can be customized as desired. The size and shape of the buttons can be designed as desired. Texts, trademarks, display windows can be matched as desired. The appearance is beautiful and fashionable. Colors do not fade. The component does not deform. It is durable.

Capacitive touch membrane switches solve the problems that metal panels and mechanical panels have. They can directly replace existing ordinary panels (metal keyboards, membrane keyboards, conductive adhesive keyboards) due to reliability and beautiful design.

Features

No direct touch required

The device can accurately detect effective finger touches, ensuring that the product's sensitivity, stability, reliability will not be affected by changes in environmental conditions or long-term use. Even 20mm of insulating material shell (glass, plastic, etc.) is not a problem for sensing.

Simple application

Single chip, very few peripheral parts, very simple circuit, no oscillation circuit required, simple production process, just layout according to the schematic diagram to get satisfactory results.

One single button, interfaces with multiple special requirements, and there is no need to modify the MCU main control program at all. It is very easy to interface with the microcontroller to implement various touch control applications.

Free adjustment

You can freely adjust the execution time of touch sensing according to requirements.

Advanced technology

Capacitive touch membrane switch has unique function to avoid mis-activated keystrokes. It has a single 3-5V power supply, a wide voltage range and low power consumption. The built-in stabilized voltage power supply can be directly accessed.

The touch button sensing series IC has automatic correction and compensation functions, eliminating the need for complex production adjustments. It is suitable for mass production. It adopts the principle of capacitive sensing. The design is casual and fashionable. With the glass panel, it is not afraid of liquid splashing, and can still maintain normal control functions.

Wide range of applications

Capacitive touch membrane switches are suitable for audio panels, telephone control keyboards, instrument control panels, washing machine control panels, intelligent access control system control panels, various small household appliances (induction cookers, disinfection cabinets, microwave ovens, etc.).

They have covered household appliances, handheld devices, industrial controls, automobiles electronics, military products and other almost all application fields involving control button operation panels.

High cost performance

Capacitive touch membrane switches have becoming the most competitive and cost-effective products. They are the industry pioneers in popularizing and standardizing touch applications.
