If you are considering purchasing a capacitive film switch, it is important to know how it works. How does the capacitive film switch work? What are the advantages of capacitive film switches?

What are the characteristics of capacitive film switches?
The capacitive film switch is a touch sensitive switch that is activated when the user makes contact with the sensor. The membrane switch uses capacitive sensing technology to perform the functions of traditional membrane switches in a simple, light touch manner. Capacitive touch film switches offer great design flexibility, durability and a smooth appearance. The thin-film switch technology uses conductive carbon to print a circuit to generate an electric field. When a human finger touches a key, the increase in capacitance is recognized by the integrated circuit, which activates the output of the key.
1. A capacitive switch is a touch-controlled electronic switch that operates by measuring changes in capacitance. It works the same way as a typical capacitive smartphone: When you touch its surface - assuming you're not wearing gloves - a small charge transfers from your body to the switch, subsequently causing a change in capacitance. The switch detects this change and responds with the appropriate command.
2. When a capacitive switch is touched, this charge interferes with the charge of the switch itself; And that causes a change in capacitance. Because of this variation, the switch can recognize when and where the touch occurred, which is basically how capacitive switches work.
1. Free adjustment -- free adjustment of touch sensing execution time (sensitivity) according to requirements;
2. No noise pollution - because some products do not need noise pollution, such as recording studios, hospitals, etc. capacitive film switches have no shrapnel or embossing process, so there is no tactile feedback or sound.
3. Excellent waterproof performance, because the traditional mechanical keyboard is different, the traditional capacitive touch film switch can achieve IP65 or even IP67 waterproof film switch
4. Easy to clean, chemical resistant - Because most of the materials are glass or PET, with flat structure, very easy to clean. The properties of this material make it resistant to corrosion and chemicals.
5. A wide range of applications - audio panel, telephone control keyboard, instrument control panel, washing machine control panel, intelligent access control system control panel, all kinds of small household appliances (induction cooker, disinfection cabinet, microwave oven......) , covering household appliances, handheld devices, industrial control, automotive electronics, military products and so on, almost all applications are involved in the control button operation panel.
6. Longer life - Since metal domes are eliminated, there is no life limit for metal domes, it all depends on the life of the material. Because the material of capacitive contact film switch is glass, PET and PC, the service life can reach millions of times.
If you are looking for a good quality and reasonable price of Capacitive Membrane Switches, LuphiTouch can provide you with the best.
LuphiTouch,a professional OEM manufacturer of user interface subassembly products.LuphiTouch is located in south of China in Dongguan,and since 2008 the core of its business is manufacturing an export of membrane switches & keypads, capacitive switches, silicone Rubbert keypads, graphic overlays, and touchscreen panels. Besides,they also offer mechanical design and PCBA development, as well as development of single-chip solutions, keypad backlighting, and turnkey assembly.
The production of high-tech interface products requires clean and well functioning operations.let's get to know that how LuPhi complies with industry requirements.
The factory has many strengths-we use high quality imported raw materials and have a skillful team of workers,as well as modern production and testing equipment,our facility is certified with ISO 9001,medical ISO13485,environmental ISO14001,health and safety ISO45001, and the production areas are equipped with 10000 and 1000 class cleanrooms.our products obtain main quality certificates for major markets, such as Europe,North America and Australia.
let's go to the workshops to see how the products are made！
Design: First，the product concept takes shape in the R&D department，where LuPhi's engineers design and create initial samples.
before mass production,their PP samples will undergo various function and environmental testing, such as button actuation life testing,high-low temperature constant temperature,and humidity testing,as well as salt-spray & waterproof testing,ink adhesion force testing,click ratio test, and many others.
01 KEY PROCESS OF PRODUCTION
Once the pre-production samples pass all necessary testing and materials arrive at the factory,production begins.LuPhi uses high-quality imported materials, such as 3M adhesive,Autotex polyester,nikomatic connectors, and many other components.
The first step of production starts from raw material cutting- where overlay films,circuit films and adhesive layers are cut by automatic cutting machines with high accuracy.
After that,the cut materials are transferred to a silk screen printing workshop,where first the ink is prepared to match the exact color requirements of the customer, and silkscreens are created for printing.
Then films and screens are moved to automatic and semi-automatic silk screen printing machines.
Following the printing,semi-finished products,are further passed to a baking treatment in a 12-meter drying tunnel until the ink is completely dried and cured, LuPhi also has 4 drying ovens to increase efficiency at this step.
For many membrane switches with embossed buttons，the printed graphic overlays also undergo embossing in semi-automatic embossing machines.
In the end, all layers of the final products, such as graphic layers, adhesive layers, circuit layers and others are assembled and laminated together, creating the about-to-be final membrane switch.
After assembly,products are passed to auto die cutting&high accuracy cutting machines to cut out the membrane switch panels and form the final product shape.
At each production step,products are fully inspected with 100% appearance and function check, to ensure that every product received by customers is qualified.
Our QC inspectors check the dimensions, printings, workmanship and electrical functions, which undergo testing twice after the circuit is printed and assembly is finished.
Packing: Once products pass the inspection, they'll be cleaned, packed into inner and expert packaging, and shipped to customers all over the world.
02 COMPANY DEVELOPMENT
With our team, about our history and recent achievements:Luphi was established in 2008 for production of human interface products. to support customers from various industries, including automotive, industrial,medical&healthcare industry, household appliances, and others.
over the past year, we achieve a 40% increase in sales through the concerted efforts of the whole team.At the same time, we have straightened the corporate culture, further improve employee satisfaction and happiness index,enhance team cohesion,and laid a solid foundation for the future performance growth.
How are we planning to support the strong demand at the market, in the next couple of years?To support the market demand in customer’s needs,in the next 5 to 10 years,we will increase investment into research and development, and will develop user interface modules for a variety of coffee machines, mixers, vending machines,juicers and other small household appliances.
At the same time,we will continue to strengthen the development and customization ability in high-end application fields,and achieve standardization in middle and low-end needs and customization of high-end needs.
03FACTORY AUDIT, SUMMARY
Now, end of tour to LuphiTouch, These have several advantages of the factory-our facility follows : ISO9001, medical ISO13485,environmental ISO14001, health & safety ISO 45001, and production areas are equipped with 10000 class and 1000 class cleanrooms, that guarantees a clean environment for manufacturing.
