Manufactured using automotive-grade polyester substrates, precision printed silver/copper traces, and marine-spec 3M adhesives designed to withstand Canterbury's dynamic thermal cycle.
A matrix membrane switch utilizes an X-Y grid system of intersecting conductive traces, separated by an insulating spacer layer with die-cut switch chambers. When depressed, the top contact bridges the circuit to register a precise keystroke while drastically minimizing MCU pin count requirements.
We eliminate atmospheric venting in washdown applications by engineering interconnected internal relief channels and boundary perimeter gaskets using 3M VHB or 3M 300LSE adhesive matrices. This guarantees uncompromised ingress barriers up to IP67 and NEMA 4X compliance.
For high-vibration equipment, mission-critical instrumentation, or ultra-dense matrix interconnections, our factory manufactures copper-etched Polyimide Flexible Printed Circuits (FPC). Etched copper traces offer near-zero lead resistance, greater flex endurance, and reliable automated SMT component soldering.
Christchurch and the wider Canterbury region experience elevated UV indices and rapid temperature fluctuations from the Southern Alps. We employ bi-axially oriented Autotype MacDermid Autotex PET films with anti-glare, UV-stabilized, and chemical-resistant hardcoats that resist yellowing and embrittlement.

From the high-tech electronics hubs in Addington and Wigram to the massive agricultural machinery plants throughout Mid-Canterbury, our custom matrix membrane switches power key technological infrastructure.
Canterbury represents New Zealand's heartland for pivot irrigation systems, automated dairy shed monitoring, automated drafting gates, and tractor telematics consoles.
Christchurch's expanding health technology precinct demands compliant, sterile human-interface control surfaces for laboratory analyzers, clinic interfaces, and patient monitors.
Home to pioneering aerospace firms and specialized field radio electronics, Christchurch manufacturers require dependable matrix panels capable of surviving severe shock and vibration.
As original equipment manufacturers in Christchurch move toward Industry 4.0 and integrated smart control enclosures, matrix membrane switches are evolving beyond basic mechanical contacts.
Modern industrial equipment increasingly integrates capacitive touch sensor arrays into the same thin-profile overlay as physical safety-critical tactile buttons. This architecture gives Christchurch engineers capacitive sliding adjusters and multi-touch convenience while preserving physical E-stop or prime buttons that require decisive actuation.
Traditional discrete LED indicators can suffer from light bleed and excessive thickness. We deploy precision micro-dot patterned LGF layers just 0.125mm thick, distributing side-firing LED illumination evenly across complex icons. Paired with dead-front graphics, icons remain invisible until lit, creating a modern, sleek aesthetic for clean-tech instruments.
With New Zealand's rigorous environmental commitments, local buyers require components free of hazardous heavy metals and solvent outgassing. Our manufacturing strictly complies with RoHS 3, REACH (SVHC), and uses non-toxic, solvent-free UV-curable inks with recyclable polyester carrier films.
Backing your supply chain with certified direct manufacturing, eliminating trading company markups, communication bottlenecks, and quality variance.
Unlike broker agencies that outsource screen printing, laser die-cutting, or lamination to different vendors, our Xianghe and Huizhou industrial bases control all production processes in-house. From artwork engineering, film master generation, and class 10,000 cleanroom silkscreening to digital UV printing, metal dome placement, and auto-punching.
Our long-term technical partnership with a veteran German membrane switch plant ensures that our process controls, ink adhesion testing, and dimensional tolerancing adhere directly to stringent European and Australasian industrial standards.
Reliability is measured through empirical qualification. Before dispatching orders to Christchurch, every production batch undergo stringent mechanical and climatic stress routines inside our in-house testing center.
Our inspection workflow utilizes computer-automated 100% circuit continuity testers, high-cycle key actuation load analyzers, programmable temperature/humidity chambers (-40°C to +120°C), automatic salt fog chambers for coastal corrosion validation, and Xenon lamp weatherometers to guarantee long-term UV resistance.
Clear, direct answers regarding custom CAD engineering, rapid prototyping, material choices, shipping, and import requirements.
