JA EN DE FR ES RU JA Providing high-durability, IP67-sealed membrane keypads, capacitive touch panels, and custom graphic overlays to electronics manufacturers across Zurich, Winterthur, Schlieren, and the broader Swiss canton region.
The Greater Zurich Area represents one of Europe's most rigorous industrial landscapes, characterized by leading medical device clusters, ultra-precise laboratory instrumentation, advanced robotics, and heavy-duty industrial automation. Human-Machine Interfaces (HMI) built for this market demand uncompromising reliability, chemical resistance, electromagnetic compatibility (EMC), and superior tactile feedback.
As an established OEM/ODM manufacturer with over two decades of production heritage, Dongguan Ravo Electronics Co., Ltd. serves as a direct engineering partner and exporter to Zurich-based technology enterprises. From initial Design for Manufacturability (DFM) reviews to high-precision screen printing, cleanroom lamination, and 100% automated electrical testing, we deliver custom membrane switch solutions that seamlessly integrate into Swiss end-user equipment.

How Swiss equipment designers implement Ravo's custom membrane switch technology across critical manufacturing and laboratory sectors.
The Bio-Technopark in Schlieren and Zurich’s medical tech firms develop sterilizable diagnostic devices, centrifuge controls, and patient care monitors. Membrane keypads designed for this sector utilize chemically resistant polyester films (such as MacDermid Autotex XE) capable of enduring daily wipe-downs with harsh hospital disinfectants (Isopropanol, Bleach, Ethanol). Antimicrobial surface coatings prevent pathogen build-up, while seamless flat overlays prevent fluid ingress into sensitive electronics.
Precision machinery builders in Winterthur and Greater Zurich demand extreme ruggedization. Our metal-dome membrane switches incorporate perimeter sealing gaskets rated up to IP67, shielding internal silver circuits against cutting fluids, lubricating oils, micro-vibrations, and dust. Custom key embossing provides crisp tactile feedback through heavy work gloves, ensuring error-free machine operation on automated factory lines.
Switzerland’s focus on energy efficiency and smart building infrastructure requires intuitive control interfaces for HVAC systems, solar inverter units, and heat pumps. We supply UV-resistant polycarbonate and polyester graphic overlays with integrated LCD/OLED display windows and light-guide film (LGF) backlighting for easy daytime clarity and soft night-time illumination.
Swiss commercial kitchen appliances, automated coffee machines, and water filtration equipment operate in hot, moist environments. Our heat-resistant PET membrane switches with 3M 200MP / 300LSE pressure-sensitive adhesives prevent edge lifting under elevated ambient temperatures and moisture, maintaining an airtight hygienic seal over years of constant usage.
Market intelligence and technological transitions observed across Swiss engineering departments.
Swiss medical and laboratory instrument developers are moving away from purely mechanical buttons toward glass-like capacitive touch interfaces. However, to preserve user safety in critical procedures, OEMs are adopting hybrid panels—combining sleek capacitive touch key pads for routine menus with tactile metal-dome physical emergency stop or primary function keys on a single integrated layer stack.
As equipment enclosures shrink, traditional screen-printed silver ink flex tails are increasingly replaced by polyimide copper FPC circuits. FPC enables tighter lead pitches (down to 0.5mm), soldered surface-mount components (SMD LEDs, resistors, ICs), superior trace conductivity, and tight bend radii without risk of silver migration or trace cracking under continuous vibration.
Zurich buyers require full material transparency under European safety standards. All raw materials used by Ravo—including films, conductive silver pastes, UV inks, barrier adhesives, and connectors—comply fully with EU RoHS 3 (Directive 2015/863) and REACH SVHC regulations. Full chemical declarations and test reports are supplied with production batches.

Combining direct Chinese manufacturing cost efficiency with international engineering standards and rapid execution.
Our engineering desk conducts comprehensive Design for Manufacturability (DFM) reviews within ≤ 2 hours. Prototype orders start from just 1 piece, allowing Swiss R&D teams to validate fit, finish, key actuation force, and pinouts rapidly before mass production.
Every membrane switch produced undergoes automated electrical continuity testing, resistance checking, loop test, and visual inspection. Actuation force, LED color consistency, dome spring-back, and adhesive shear strength are sampled per ISO 9001 guidelines.
We provide express air freight shipping directly to Zurich Airport (ZRH) or Swiss regional facilities with full export customs clearance documentation. ESD-safe packaging and moisture-barrier vacuum packing guarantee pristine condition upon arrival.
