Custom Membrane Switch Factories & Suppliers serving the Madrid Market

To generate manufacturing tooling and production films, our 10-person CAD engineering department requires mechanical outline drawings in vector formats such as AutoCAD DXF/DWG, STEP, or IGES specifying all cutout dimensions, key embossing profiles, and tail egress coordinates. Graphic overlay artwork should be provided in Adobe Illustrator (AI), vector PDF, or CorelDraw with defined Pantone (PMS) or RAL color references and text converted to curves. Circuit traces can be supplied as electrical schematics, pinout tables, or Gerber RS-274X data.

Engineering prototype samples (typically 5 to 10 finished pieces) are completed within 7 to 10 business days following final approval of our digital engineering drawing (PDF/DWG proof). Production tooling is manufactured in-house using CNC machining centers to minimize lag. Volume series production (500 to 50,000+ units) typically requires 2 to 3 weeks depending on multilayer component complexity. Air courier delivery (DHL, FedEx, UPS) to Barajas Airport or direct to your facility in Madrid takes an additional 3 to 5 business days.

Silver migration occurs when an electric field across adjacent silver conductive traces induces electrochemical dendrite growth in the presence of moisture. TAVO prevents this failure mode through three preventative measures: (1) overprinting all silver circuit traces with a continuous carbon-graphite protective barrier layer, (2) applying a thermally-cured dielectric insulation mask over all non-contact zones, and (3) maintaining strict trace pitch spacing rules (>0.5mm for higher DC biases). For mission-critical aerospace or medical switches, we recommend our etched copper Flexible Printed Circuit (FPC) architecture with polyimide coverlay, which eliminates silver paste entirely.

For indoor consumer electronics, polycarbonate (PC) offers high optical clarity and economical cost. However, for Madrid’s exterior outdoor systems (e.g., EV chargers, ticket vending kiosks) and aggressive factory floors, we recommend premium biaxially-oriented polyester (PET) such as MacDermid Autotex XE or Autoflex. XE-grade polyester incorporates an integrated UV-blocking hardcoat that resists yellowing, embrittlement, and micro-cracking caused by intense solar exposure, while delivering superior chemical immunity against diesel fuels, hydraulic fluids, alcohols, and industrial solvents.

We support flexible international trade arrangements including DAP (Delivered at Place) and DDP (Delivered Duty Paid) to Madrid addresses, as well as standard EXW, FOB (Shenzhen/Tianjin), and CIF terms. Our export documentation team provides accurate HS Tariff Classification codes (typically 8537.10 or 8538.90 for industrial control boards and switch panels), full commercial invoices, packing lists, and Certificates of Origin (Form A) to ensure seamless clearance through the Spanish Tax Agency (Agencia Tributaria - Aduanas).

Yes. We regularly execute bilingual English/Spanish Non-Disclosure and Confidentiality Agreements prior to receiving client drawings, schematics, or CAD files. Intellectual property protection is strictly enforced throughout our organization. Your proprietary layouts, custom graphic artworks, firmware specifications, and project applications are securely archived with restricted engineering access and will never be shared with third parties or competitors.
