Get a Working Membrane Switch Prototype in < 48 Hours


Step 1 – Upload your drawing (AI / DXF / PDF) or just describe the key layout.

Step 2 – Receive a digital proof + ΔE color report within 12 h.

Step 3 – Approve and we laser-cut, screen-print, assemble, and ship in 24–48 h.  

Initiate your custom membrane switch order with our streamlined three-step process.

Begin by submitting your detailed membrane switch design. You can upload your artwork in standard formats like Adobe Illustrator (.AI), AutoCAD Drawing Exchange Format (.DXF), or Portable Document Format (.PDF). If you don't have a design file ready, simply describe your desired key layout and any critical specifications. This ensures we fully grasp your vision for the membrane switch's functionality and appearance.

Once we receive your submission, our team will promptly generate a digital proof of your membrane switch design. Alongside this visual representation, we will provide a Delta E (ΔE) color report. This report quantifies the color accuracy, assuring that the printed colors will precisely match your specified requirements. You will receive both of these crucial items within a 12-hour turnaround time.

After you review and approve the digital proof and color report, we move to production. Our advanced laser cutting technology precisely shapes the membrane switch layers. Precision screen printing applies your custom graphics, legends, and conductive traces. We then meticulously assemble all components, ensuring every switch functions perfectly. This entire manufacturing and assembly process, from approval to shipment, is completed within a rapid 24 to 48-hour window.

How to Start


1. Send file – AI, DXF, PDF, or hand sketch  
2. Get quote – within 12 h  
3. Approve proof – color ΔE < 1  
4. Ship – DHL 3–5 days worldwide (included)

Begin by sharing your design file. We accept various formats. Send us your AI, DXF, or PDF files. A clear hand sketch is also welcome. This initial step gets your project started quickly.

Next, you will receive a personalized quote. We provide this within twelve hours of receiving your file. Our team carefully reviews your design. We consider material, size, and complexity. This ensures an accurate price.

Once you approve the quote, we create a proof. This proof shows your item before production. We check color accuracy. The color difference, or Delta E, is less than one. This means colors match your original design very closely.

Your approved order will then ship. We use DHL for fast delivery. Shipping takes three to five days. This covers worldwide delivery. We include shipping costs in your quote. You get your custom item directly.

Detailed Introduction of EMI Shielding Membrane Switch

图片
In an era where electronic devices are increasingly compact and interconnected, electromagnetic interference (EMI), radio-frequency interference (RFI), and electrostatic discharge (ESD) pose significant threats to device performance. EMI shielding membrane switches are engineered to mitigate these risks, ensuring reliable operation in critical applications. This technology combines advanced materials and precision design to create a protective barrier against unwanted electrical noise. How EMI Shielding Membrane Switches Work EMI shielding membrane switches utilize conductive layers to block or absorb electromagnetic waves. The core principle involves creating a barrier—often referred to as a "Faraday cage"—that reflects or dissipates interference before it reaches sensitive circuitry. Key mechanisms include: Reflection : Conductive materials like copper or silver ink reflect high-frequency EMI/RFI signals. Absorption : Layered composites absorb and convert electromagnetic en...
