Engineered for seamless integration with rigid PCBs, flex FPC circuits, and harsh environment human-machine interfaces exported directly to OEM assemblers in Suva.
Standard electronic tactile switches fail prematurely in Fiji due to ambient humidity, coastal saline aerosols, and sudden thermal fluctuations. Here is how our single layer metal dome arrays provide uninterrupted reliability.
Deploys in radarconsoles, depth sounders, VHF transceivers, and engine telematics operating out of the Port of Suva and Walu Bay ship repair yards. SUS301 stainless steel domes plated with 24K hard gold prevent electrolytic pitting and oxidation caused by pervasive airborne salt spray, maintaining actuation crispness even when operated by operators wearing heavy wet-weather sea gloves.
Servicing automated juice extraction boilers, distillation monitoring cabinets, and packaging lines at major Fijian processing complexes. Single-layer dome sheets utilize high-adhesion 3M 300LSE adhesive matrices resistant to aggressive sugar aerosols, high pressure washdowns, and continuous vibrational cycles that displace generic PCB pushbuttons.
Custom-engineered 3X3 and 4X5 matrix single-layer dome arrays power coastal fuel pump terminals and solar-microgrid smart energy metering throughout Viti Levu. UV-stabilized overlay polymers resist prolonged sun exposure and cracking caused by equatorial solar radiation, ensuring uninterrupted financial transaction entry and volumetric fuel delivery.
As Suva solidifies its standing as the diplomatic, maritime, and technological financial hub of the South Pacific, local manufacturing and technical engineering firms are rapidly replacing electromechanical switches with hermetically sealed tactile dome arrays.
Three structural shifts are dictating procurement protocols across Fiji’s government infrastructural renewals and private fabrication sectors:
Dongguan Cevra delivers direct container and courier export channels directly clearing through Suva customs, ensuring procurement teams avoid multiple distribution markups while obtaining traceable certificates of conformity (CoC).
Comparative design criteria for design engineers choosing between standard commercial tactile sheets and Cevra’s marine-grade tropicalized configurations.
| Engineering Parameter | Commercial Grade (Standard) | Cevra Suva Marine-Tropical Grade (Recommended) |
|---|---|---|

| Surface Contact Plating | Bare Stainless / Light Tin | Heavy Electrolytic Nickel Plating or 24K Hard Gold Flash |
| Carrier & Retention Film | Generic 0.05mm Polyester Tape | Optically Clear Anti-Static Mylar (PET) with Air Relief Conduits |
| Perimeter Adhesive System | Water-based Synthetic Acrylic | 3M 467MP / 3M 300LSE Differential Acrylic (Solvent Proof) |
| Switch Actuation Life | 100,000 – 300,000 Cycles | > 1,000,000 Cycles Rated (Certified via Dynamic Load Testing) |
| Contact Resistance | < 1.0 Ω Initial | < 0.1 Ω Ultra-Stable Contact Impedance |
| Operating Temp & Humidity | 0°C to +50°C | 80% RH Non-Condensing | -40°C to +85°C | 98% Relative Humidity (Tested per IEC 60068-2-78) |
| Tactile Ratio (Feel) | 35% – 45% (Soft mushy feel) | 50% – 65% (Crisp, definitive click feedback even with work gloves) |
Operating from our 2,600㎡ purpose-built manufacturing facility, we manage every step under certified ISO 9001:2015 protocols, audited and onsite-verified by SGS Group.
We do not broker components. All four-leg cross domes, round snap domes, oblong buttons, and triangular snap elements are stamped on high-speed precision presses, ensuring uniform snap ratio, crisp travel height, and tight force tolerances (±15g).
Single layer dome sheets are compiled using automated alignment placement machinery integrated with high-resolution CCD visual positioning cameras. This guarantees dome-to-pad pitch accuracy within ±0.05mm, eliminating ghost clicks and off-center binding.
Before leaving our factory, your shipment is tested against rigorous reliability procedures: dome load curve analyzers, holding tack shear testers, peel adhesion scales, pencil hardness testing, and thermal/humidity stress cabinets (-40°C to +105°C cycles).

Suva experiences average humidity levels consistently exceeding 80% combined with high airborne marine salts. Unprotected metal domes suffer galvanic corrosion and contact resistance spikes. Cevra combats this by utilizing cold-rolled SUS301 stainless steel with optioned electrolytic bright nickel or 24K pure gold plating. Additionally, our single layer arrays feature a hermetically laminated top carrier tape using industrial 3M adhesives (such as 3M 467MP or 300LSE). When laminated onto your PCB or circuit layer, the adhesive seals the contact chamber against ambient air, moisture ingress, and corrosive aerosol penetration.
To produce an exact match single layer dome array, we require your PCB Gerber files (specifically the switch contact pad layer and board outline), mechanical CAD drawings in DXF, DWG, or STEP format, and details on your desired actuation parameters: dome diameter (standard 4mm to 20mm), actuation trip force (160g, 220g, 280g, 350g, etc.), key quantity, and preferred adhesive border thickness. If you have an existing physical sample from a legacy installation in Fiji, our reverse-engineering team can scan, digitize, and recreate the exact stack-up.
We support prototype validation, municipal proof-of-concepts, and full-scale factory production. Custom single-layer dome array prototype batches begin at just 50 to 100 units. For mass production, our automated lines provide tiered volume pricing scaling from 1,000 units to several hundred thousand pieces. Prototype engineering samples are typically completed and dispatched within 5 to 7 business days following drawing sign-off.
Our export division arranges consolidated express air courier (DHL Express, FedEx, UPS) directly from Shenzhen/Hong Kong to Nausori International Airport or Nadi International Airport, with doorstep clearance to your facility in Suva within 4 to 6 business days. For high-volume manufacturing runs or bulk container shipments, we ship ocean freight routed from Nansha or Yantian ports straight into the Port of Suva, handling all commercial invoicing, Packing Lists, Certificates of Origin (CO), and HS Tariff documentation for frictionless clearance through the Fiji Revenue and Customs Service (FRCS).
Hand-soldering or individually pick-and-placing loose tactile domes onto PCBs is labor-intensive, error-prone, and presents severe risks of flux residue contaminating dome contact feet. A custom single layer dome array groups all necessary buttons onto a single pre-spaced, optically clear adhesive carrier sheet. Your assembly team simply peels the protective liner and applies the entire array onto the circuit board in one swift, highly accurate motion. This reduces assembly time by up to 80% while establishing an immediate ingress seal around every switch contact.
