Features and Advantages of Capacitive Membrane Switches

Capacitive membrane switch is a Membrane switch that switches on and changes the capacitance to operate. The realization of the function also depends on the IC to recognize the change of capacitance. Capacitive membrane switches have all the advantages of membrane switches-design flexibility, easy cleaning and good sealing.

New trends and designs of capacitive membrane switches:

As customers have higher and higher requirements for products, they even hope to extend the way the products are used.

1. Niceone-tech uses LEDs layer as the bottom line and combines capacitive membrane switches to form LEDs capacitive membrane switches. This type of product can be used in the dark.

2. Generally, the thickness of the capacitive membrane switch can be designed to be less than 1mm. The flat design is conducive to the dustproof and waterproof of the product.

3. Capacitive membrane switch products are easy to clean without embossing and are resistant to friction. Compared with conventional mechanical switches, capacitive membrane switches can do it.

4. The color printing technology can be combined with the capacitive membrane switch to form a more colorful product. More in line with the aesthetic requirements of customers.

5. It can be designed into the latest LGF capacitive membrane switch, with uniform light-emitting effect, and the thickness can be controlled below 1mm.

Material selection of capacitive membrane switch:

The panel can be made of PET materials such as AUTOTYPE and PC such as GE. Such materials are more resistant to chemical substances. The panel material can also choose antibacterial materials to resist bacteria, which is widely used in laboratories and hospitals. The panel can also be selected from materials that resist ultraviolet rays, so that the capacitive membrane switch can also be used outdoors without being easily aging.

The combination of ESD and capacitive membrane switch is used to prevent static electricity from damaging the product. Most ESD can be made by choosing transparent conductive silver oil, so that the formed ESD shielding layer can be combined with the Backlight to form a backlit membrane switch panel.

There are many choices of adhesive tape: if it is used in an environment with a waterproof level and temperature of -20-80 degrees Celsius, it is more recommended that customers use 3M and Nitto adhesive tape.

When you need to control costs-when meeting the needs of use, you can consider cost factors to choose an economical Chinese brand of adhesive tape-DT adhesive. Although the use temperature is controlled at 10-60 degrees Celsius, it is sufficient for use in a regular environment .

Some extended topics about capacitive membrane switches:

1. By choosing anti-scratch materials, the capacitive membrane switch will not be scratched or scratched even if it is used for a long time. Anti-scratch materials generally include EBG, hardened PC or hardened glass, etc., and are usually used as the panel of capacitive membrane switches.

2. When it is necessary to choose membrane switch products with a particularly long life, Niceone-tech,a trusted membrane keypad manufacturer will recommend customers use a Non-tactile membrane switch. The capacitive membrane switch also belongs to this type of product. Since there are no embossing buttons and metal dome, choose ink with stronger adhesion, which can last the product for 1-3 years.
