Export-Standard Solutions
OEM Precision Membrane Switch & Tactile Dome Assemblies
From medical diagnostic instrumentation to ruggedized industrial push-buttons, our factory delivers micro-engineered layer stack-ups configured for maximum actuation lifespan and extreme environmental resilience.
Enterprise Core Capabilities
Direct-from-Manufacturer OEM/ODM Excellence
Unlike sourcing brokers or trading intermediaries, Dongguan Cevra Electronic Technology operates closed-loop vertical manufacturing—from raw polycarbonate/PET conditioning to automated precision laser cutting and high-stability SMT integration.
Hermetic Environmental Sealing
Tropical island installations require protection against continuous humidity, saline marine air, and fine particulates. We apply continuous Perimeter Seal Adhesives (3M 200MP / 300LSE) with micro-venting Gore membranes that stabilize internal air cavity pressures without allowing moisture ingress.
SUS301 Tactile Longevity
Every snap dome array utilizes certified Japanese austenitic SUS301 stainless steel, subjected to automated spring-rate and dome load testers. Domes achieve click lifespans surpassing 1,000,000 to 5,000,000 actuations while preserving tactile snap ratios exceeding 50%.
ISO 9001 & SGS Audited Rigor
Every production batch is routed through CCD optical alignment for conductive silver track verification, automated circuit resistance tests, pencil scratch hardness checking (up to 3H-4H), and temperature thermal shock cycling (-40°C to +85°C).
Local Operating Environments
Engineering Membrane Switches for Jamaica's Industrial Landscape
Industrial operators and hardware developers across Kingston, Montego Bay, Mandeville, and Spanish Town face specific environmental challenges: high atmospheric salt concentrations, elevated year-round ultraviolet radiation, and corrosive dusts.
Mitigating Salt-Air Galvanic Oxidation & High Humidity
In coastal processing centers and transshipment terminals like Kingston Harbour, conventional exposed mechanical keypads suffer from rapid contact pitting, corrosion, and silver migration caused by trace moisture entrapment. Cevra mitigates these failure modes through advanced polymeric construction:
We deploy dielectric protective carbon or graphite overcoating across conductive silver circuit traces, coupled with chemically inert Autotex XE polyester films. This construction blocks humidity vapor transmission rates (WVTR) and prevents electrochemical silver dendritic formation even under constant 95% relative humidity at 40°C.
Anti-Silver Migration Overcoat
Autotex XE UV-Resistant PET
IP67/NEMA 4X Ingress Protection
Resisting Bauxite Particulates & Agro-Industrial Sanitizers
In Jamaica's bauxite-alumina refineries around Manchester and St. Ann, as well as rum distilleries and sugar processing facilities across Clarendon, user interfaces are constantly exposed to caustic washdowns, alcohol vapors, and abrasive red-mud mineral dust. Traditional mechanical push-buttons accumulate grime within mechanical crevices, resulting in stuck actuators.
Our flat and embossed membrane panels provide unbroken, smooth graphic surfaces featuring chemically textured finishes. The surface is impervious to caustic soda (NaOH), isopropyl alcohol sanitizers, and dilute acids, allowing operators to pressure-wash control interfaces without electrical shorting.
Caustic Washdown Resistant
Sealed Micro-Travel Domes
High-Tack 3M LSE Adhesives
Port & Maritime Digitization
Automated crane controls, container terminal logistics scanners, and marina fuel distribution consoles at Montego Bay and Kingston utilize tactile dome keypads resistant to direct wave splash and salt crystal scouring.
Solar & Microgrid Expansion
Jamaica's national move toward independent solar power plants creates sustained demand for outdoor-rated inverter interfaces that tolerate high UV indices (UV index 11+) without chalking, fading, or embrittlement.
Hospital & Clinical Upgrades
Medical centers in Kingston are modernizing sterilization monitors, fluid infusion pumps, and portable diagnostic terminals requiring antimicrobial overlay films that remain clean after continuous chlorine disinfectants.
Hospitality & Point-of-Sale
Resort-grade access control, perimeter security stations, and outdoor ticketing panels demand backlit capacitive touch switches engineered with low standby draw and responsive performance under humid weather.

Procurement Knowledge Base
Frequently Asked Questions by Caribbean Buyers
Everything procurement directors, electronic design engineers, and equipment assemblers need to know regarding delivery, customization, and tropical operating conditions.
How do Cevra's membrane switches survive Jamaica's tropical maritime environment?
We configure specialized layer stacks incorporating Autotex XE or MacDermid Autotype outdoor-grade UV-stabilized polyesters. Unlike standard Polycarbonate (PC) which can yellow and craze under Caribbean ultraviolet indices, our stabilized PET resists UV breakdown. Internal silver conductor circuits are protected with a dielectric passivating coat to prevent silver migration caused by high humidity, and layered with 3M 300LSE adhesive gaskets to prevent moisture ingress.
What design files and specifications are needed to receive a DFM quote?
You can provide your mechanical outline drawings in Vector formats (DXF, DWG, STEP) alongside your graphic artwork (Adobe Illustrator .AI, PDF, CorelDraw) with Pantone (PMS) or RAL color specifications. Include details regarding tactile snap force requirements, tail pitch (e.g., 2.54mm or 1.0mm pitch ZIF connectors), circuit schematics (matrix or common bus), and operational temperature envelopes. Our engineering team returns a full Design-For-Manufacturability (DFM) review within 24 hours.
What are the lead times and shipping routes to Kingston and Montego Bay?
Rapid prototyping samples are completed within 5 to 7 business days following drawing sign-off. Mass production runs typically ship within 12 to 18 business days. For urgent deliveries to Jamaican facilities, shipments are expedited via DHL, FedEx, or UPS air freight directly from our Dongguan factory, arriving at Norman Manley International (KIN) or Sangster International (MBJ) in 4 to 6 transit days with pre-cleared customs commercial invoices.
Can you replicate or reverse-engineer legacy membrane switches for obsolete machinery?
Yes. Many agricultural processing and sugar refining machines in Jamaica operate with discontinued control panels. If CAD drawings are unavailable, you can ship a sample keypad to our testing lab. We utilize high-resolution optical scanners and multi-channel continuity meters to map circuit paths, reverse-engineer the graphic overlay, reproduce embossed profiles, and create identical drop-in replacements.
What is the Minimum Order Quantity (MOQ) for custom-printed overlays and switches?
To support equipment builders and maintenance engineers, our prototype MOQ begins at 10 to 50 pieces for membrane switch assemblies, and down to 10 pieces for graphic overlays. Mass production volumes can scale smoothly up to hundreds of thousands of units, supported by our automatic screen printing and laminating production lines.
