Membrane Switch

The raw materials for membrane switches, such as polyester film, polycarbonate (PC) films, and adhesive tape, arrive in roll form. To initiate the manufacturing process, the first step is precision cutting to achieve the desired dimensions.

Yu An Electronics uses advanced cutting machines that guarantee exact measurements, ensuring uniformity and consistency throughout the entire production process.

Silver paste is crucial for creating electrical pathways and contacts on the membrane switch. It has good conductivity and lower resistance, which is very suitable for membrane switch.

Yu An Electronics utilizes state-of-the-art screen-printing equipment to achieve fine silver paste patterns. This step demands precision to ensure optimal conductivity.

Graphic overlay is the visible interface of the membrane switch, it can be designed into various colors and patterns. Graphic overlay printing commonly employs screen printing or digital printing techniques to ensure pattern clarity and durability.

These methods are instrumental in imprinting complex patterns and icons onto the panel substrate to meet design and user requirements. Then high-temperature curing and baking solidify the patterns on the panel. Our expert graphic designers work closely with our printing team to ensure the overlay accurately reflects your brand and functional requirements.

Emboss is always used in touch membrane switches. For tactile feedback and enhanced user experience, embossing is a critical step in our production process. Embossing provides a distinct feel when pressing buttons on the membrane switch. Additionally, emboss also can serve as an indicator for blind person or when used in dark and night environment.

Yu An Electronics uses advanced embossing equipment to create custom patterns and designs that meet your specific needs.

Precision die punching is employed to cut out the individual switch keys and apertures for LED indicators, display windows, and connectors. Full-automatic die-cutting is ideal for large production runs, providing rapid efficiency to enhance production rates.

Semi-automatic die-cutting is suitable for shaping circuit layers and product formation, ensuring the accuracy of product dimensions and shapes. Laser cutting is convenient for small batch samples. Our die punching process ensures clean and accurate cuts, maintaining the integrity of the membrane switch design.

Following design specifications, the circuit layer, functional layer, and panel layer are adhered in the correct sequence. Pressure is applied using a scraper to ensure strong adhesion between the membrane layers.

Our assembly team meticulously inspects and tests each membrane switch to ensure it meets quality and performance standards before it is ready for delivery to the customer.
