Direct OEM/ODM production supporting Lausanne procurement teams with rapid prototyping, tight tactile force tolerances (±15g), and specialized surface platings.
How our precision tactile switches support the Canton of Vaud’s Health Valley, EPFL innovation spin-offs, and luxury micro-engineering standards.
Lausanne and the wider Lake Geneva area host world-leading clinical instrumentation and surgical technology firms. Our metal dome arrays provide unfailing tactile confirmation under sterile silicone covers and chemical wipe-downs. Featuring medical-grade SUS301 stainless steel with gold flash plating, our dome sheets eliminate micro-fretting corrosion, ensuring zero-latency response in point-of-care analyzers, surgical handpieces, and infusion pumps.
Micro-mechanics manufacturers throughout Vaud and Jura require Human-Machine Interfaces (HMI) that resist vibration, metal shavings, and cutting lubricants. Cevra’s custom dome sheets are built with multi-layer PET carriers, die-cut perimeter acrylic gaskets (3M 300LSE/468MP), and internal venting channels that equalize atmospheric pressure without ingress of airborne oil mist or particulate matter.
Emerging robotics, smart environmental sensors, and sports monitoring devices incubated around the EPFL Innovation Park require ultra-slim profiles. Our single-layer and double-layer dome arrays provide a tactile z-height as thin as 0.35mm. By combining light-guide film (LGF) and integrated surface-mount micro-LEDs, we supply Lausanne engineers with lightweight, battery-efficient interface modules.
In the French-speaking hub of Lausanne, hardware procurement balances strict Swiss quality mandates (SN EN ISO standards) with the imperative of lean supply chain economics. A noticeable shift away from standard electromechanical microswitches toward custom peel-and-stick metal dome arrays is driven by three decisive engineering factors:

We are a dedicated manufacturing plant in Dongguan, China—not an export middleman or trading desk. You work directly with tactile hardware specialists.
Our 2,600㎡ manufacturing operations, personnel qualifications, and test protocols have undergone comprehensive onsite audit by SGS Group.
Equipped with internal CNC tooling, laser cutters, and screen fabrication, we deliver prototype dome array sheets to Switzerland in as few as 5 to 7 business days.
From 4-leg cross domes with dimples to triangular snap domes with central light holes, choose from nickel or gold platings with actuation forces from 120g to 600g.
Experienced in exporting to Geneva (GVA) and Zurich (ZRH) with full customs declaration, Certificate of Conformance (CoC), and Trade Assurance security.
Key information regarding material certifications, tolerances, lead times, and customs integration when sourcing metal dome sheets from China to Switzerland.
Every stamping coil of Japanese SUS301 stainless steel is verified for tensile hardness and thickness before punching. During assembly, our automated Dome Load-Displacement Testers sample parts hourly, capturing peak actuation force (F1), switch-point travel, and return snap (F2) to ensure strict adherence to ±15g or ±20g customer specifications.
Yes. For hermetically sealed enclosures common in Swiss medical and outdoor gear, we design double-layer dome arrays with micro-laser venting channels running between dome cavities. This equalizes air pressure during actuation without exposing the PCB pads to external moisture or airborne contaminants.
For clients throughout Romandie operating under ISO 13485 environments, we supply comprehensive First Article Inspection (FAI) reports, Certificates of Conformance (CoC), material technical datasheets (Autotex PET, 3M adhesive lot numbers), and third-party laboratory RoHS/REACH declarations.
Rapid tooling and custom prototypes are dispatched within 5–7 working days via DHL Express or FedEx Priority (typically arriving in Lausanne or Geneva within 3–4 days). Volume production orders (5,000 to 200,000+ sheets) typically ship within 12–16 days. DDP terms can be arranged seamlessly.
Yes. In addition to custom pre-aligned dome sheets (arrays) on PET carriers, we manufacture round, four-leg, and triangular domes packaged in standard carrier tapes (SMD tape-and-reel format) compatible with high-speed surface mount placement heads for automated Lausanne assembly lines.
We welcome native DXF, DWG, STEP, or Adobe Illustrator (AI/PDF) engineering drawings detailing key positions, outline dimensions, circuit schematics, and connector pitch. Our engineering team reviews stack-up manufacturability and returns a comprehensive DFM proposal within 24 hours.
