High-Reliability Capacitive & Membrane Interface Assemblies
Manufactured in our Intertek-verified 10,000㎡ facility in Dongguan, our human-machine interfaces combine military-grade silver and copper FPC circuitry, IP67+ perimeter ingress seals, and zero-drift capacitive actuation designed to satisfy rigorous Swiss engineering standards.
Intertek On-Site Verified Manufacturing
Dongguan AXRU Electronics Co., Ltd. operates under strict ISO 9001:2015 quality protocols. Unlike trading intermediaries, all core operations—cleanroom screen printing, circuit etching, metal-dome registration, adhesive lamination, and automated die-cutting—are centralized within our 10,000㎡ production floor.
Rapid Swiss Prototype & DFM Support
We understand the demanding time-to-market cycles of Bern's medtech and industrial machinery enterprises. Our specialized engineering desk provides comprehensive Design for Manufacturability (DFM) reviews within 24 hours, alongside rapid 5-day prototyping for capacitive sensors, membrane panels, and IMD overlays.
Proven Tier-1 Supply Chain Heritage
Over 12 years of industry specialization has established AXRU as a trusted custom manufacturer for Fortune 500 equipment builders and European tier-one brands. Our capacitive and membrane controls meet stringent RoHS, REACH, and UL flammability standards required for seamless Swiss market compliance.
Localized Applications & Engineering Fit in Canton Bern
From the medical cluster in Bern-Mittelland to precision engineering hubs in Biel/Bienne and the Bernese Jura, local equipment manufacturers demand capacitive keypads that deliver zero-maintenance longevity, rigorous ingress protection, and uncompromising aesthetic execution.
Medical & Laboratory Diagnostic Instrumentation
Bern's thriving medtech sector requires touch input interfaces capable of withstanding constant wiping with aggressive chemical sterilizers (such as Isopropyl alcohol, bleach, and quaternary ammonium compounds). Our capacitive glass and PET control panels present a continuous, crevice-free surface that eliminates bacterial accumulation and prevents fluid intrusion to IP67/IP68 standards.
Precision Watchmaking & Micro-Machining CNC Tools
In the watchmaking belt of Biel/Bienne, machine-tool builders need HMI interfaces that resist cutting oils, coolants, and intense vibration. AXRU manufactures multi-layer capacitive touch switches featuring high-hardness acrylic, chemical-resistant Autotype polyester, and hermetic perimeter seals that shield sensitive PCB controllers from aerosol ingress.
Alpine Rail, Transport & Outdoor Kiosks
Deployments across Bernese Oberland subject input systems to freezing sub-zero temperatures, intense Alpine UV solar radiation, and condensation cycles. We implement anti-UV hard coats, automotive-grade translucent inks, and wide-temp adhesive systems rated from -40°C to +85°C to ensure zero tactile failure and no optical yellowing.

Force & Displacement Tester
High-precision plotting of tactile actuation curves, snap ratios, and stroke distance to guarantee uniform switch sensation.
Key Life Cycle Tester
Pneumatic cycling rigs that stress domes and capacitive touch zones past millions of cycles to validate long-term resilience.
Temp. & Humidity Chamber
Thermal shock and accelerated environmental aging tests ranging from -40°C to +120°C at up to 95% relative humidity.
Emerging Technology Trends in the Bernese HMI Market
Swiss industrial designers and procurement teams are rapidly evolving their hardware architectures to stay ahead in energy efficiency, user ergonomics, and seamless Industry 4.0 data exchange.
Migration to Capacitive Dead-Front Panels
Bernese OEM manufacturers are increasingly phasing out mechanical push-buttons in favor of modern "dead-front" capacitive panels. When powered off, key legends disappear into a glossy or matte black fascia. Upon proximity sensing or touch, vivid LED indicators illuminate through sub-surface translucent masks, giving medical and home appliances an ultra-premium aesthetic.
Glove & Water-Tolerant Capacitive Algorithms
A primary historical hesitation with capacitive touch in Swiss heavy industries was moisture sensitivity. AXRU overcomes this by combining advanced mutual-capacitance sensor geometries with customized sensitivity tuning, allowing flawless touch detection through thick nitrile surgical gloves, mechanical work gloves, and surfaces covered with condensation.
Flexible Hybrid Electronics (FHE) & Ultra-Thin Stacks
Miniaturization in Bern's micro-engineering cluster requires interfaces with thickness budgets under 0.8mm. By leveraging micro-etched copper polyimide (FPC) circuits and zero-profile capacitive pads, we create ultra-compact human-machine interfaces that integrate directly onto existing internal host PCBs with zero chassis modification.
Frequently Asked Questions from Bernese Buyers
Direct technical answers regarding customs clearance, sample validation, material certifications, and lead times for Swiss OEM projects.
Q1 What design documents are required for an initial quotation?
To provide an accurate DFM review and firm quotation, please share your 2D CAD mechanical drawings (.DXF, .DWG, or .PDF), graphic artwork files with vector layers (.AI or vector .PDF) including Pantone/RAL color codes, layer stack-up preferences, and connector pinouts. If you have an existing sample, our engineers can fully reverse-engineer the physical and electrical parameters in-house.
Q2 How do you manage customs clearance and express logistics to Bern, Switzerland?
We provide full DDP (Delivered Duty Paid) or DAP air-express shipping via DHL, FedEx, and UPS directly to Bern, Zurich, Basel, and surrounding Swiss cantons. All customs paperwork, including detailed commercial invoices with correct HS Codes (8537.10 / 8538.90), Certificates of Origin, and packing declarations, are fully prepared to ensure zero delay through Swiss Federal Customs (BAZG).
Q3 Can capacitive keypads operate reliably through thick acrylic or front glass?
Yes. Our capacitive touch sensors can be tuned to detect input reliably through up to 6mm of tempered glass or 4mm of PMMA acrylic. During the prototyping stage, our engineering team optimizes sensor electrode geometry, dielectric spacer thickness, and trace routing according to your cover lens specifications to achieve maximum signal-to-noise ratio.
Q4 What is your policy on prototyping and Minimum Order Quantities (MOQ)?
We understand that Swiss precision manufacturing often involves specialized, high-mix low-to-mid volume production. Therefore, our standard MOQ starts at just 100 units for custom production runs. For engineering verification, pilot production samples (typically 5 to 10 pcs) are dispatched within 5 to 7 working days following CAD design approval.
Q5 How do you guarantee long-term color fidelity and graphic durability?
All graphic legends, dead-front windows, and border aesthetics are screen-printed on the reverse side (second surface) of high-grade optical polycarbonate (PC) or polyester (PET) films. Because the inks are shielded behind the transparent substrate, they are completely immune to surface abrasion, scratching, and chemical deterioration from industrial cleaners.
Q6 What material compliance certifications accompany the delivery?
Every shipment is accompanied by comprehensive quality documentation, including RoHS and REACH declarations, Certificate of Conformance (CoC), and 100% electrical inspection reports. For automotive and medical applications, we can supply full material data sheets and Initial Sample Inspection Reports (ISIR / PPAP Level 3 equivalent).
