Product SpecificationsPolydome (Polyester Dome) vs. Metal Dome Architecture
In-depth technical criteria for mechatronics and hardware engineers in Kaunas evaluating tactile response, environmental sealing, unit ergonomics, and production economics.
A Polydome Membrane Switch (also termed an embossed polyester dome switch) forms the tactile element directly out of the polyester substrate via precision thermo-forming or cold hydro-embossing tooling. Unlike conventional metal dome arrays that depend on individual stainless steel snap domes affixed within an adhesive spacer matrix, polydome architecture integrates both the tactile spring mechanism and the protective layer into a unified, monolithic sheet.
For Lithuanian hardware engineering firms operating within Kaunas Free Economic Zone (FEZ) and throughout the Kaunas Science and Technology Park, polydome switches provide unique mechanical advantages. Because the conductive silver or graphite contact pad is printed on the underside of the formed PET dome itself, polydomes eliminate the risk of internal dome displacement or contamination under severe, continuous vibration—an essential reliability factor for Kaunas-manufactured automotive diagnostics, commercial telematics, and heavy handling machinery.
| Performance Parameter | Polydome (Thermo-Formed PET) | Stainless Steel Metal Dome | Engineering Selection Matrix (Kaunas OEM Use) |
|---|---|---|---|
| Tactile Ratio & Feel | Gentle, smooth snap ratio (35% – 50%); quiet, cushioned acoustic response. | Sharp, crisp tactile click (50% – 70%); loud, noticeable auditory feedback. | Polydome is optimal for medical clinics, hospital diagnostics, and quiet office environments. |
| Rated Actuation Life | 1,000,000 to 3,000,000 cycles (material fatigue governed by PET crystallization). | 1,000,000 to 5,000,000+ cycles (governed by stainless alloy spring characteristics). | Metal dome preferred for heavy repetitive continuous industrial automation stations. |
| Sub-Zero Temperature Performance | Rated -20°C to +70°C. Cold-resistant PET films must be specified for Baltic sub-zero conditions. | Operational from -40°C to +85°C without shift in tactile force or snap recovery. | Outdoor Baltic utility and cold-storage applications should select cold-form grade PET or metal domes. |
| Switch Travel Height | 0.30 mm to 0.70 mm depending on dome diameter (4 mm to 12 mm). | 0.20 mm to 0.55 mm based on four-leg or oblong dome geometry. | Polydomes offer greater key travel when operators wear thin cleanroom or workshop gloves. |
| Component Cost Profile | Lowest cost per switch point. Zero hardware dome placement costs. | Higher unit cost due to metal dome components and precision pick-and-place taping. | Polydome provides massive cost reduction on dense keypad arrays (e.g., 20+ keys). |
| EMI / ESD Shielding Integration | Full coverage printed silver grid, carbon lattice, or solid aluminum foil backing. | Requires selective grounding tabs to metal domes or laminated shielding foil. | Polydomes provide simpler continuous layer isolation against high ESD transient spikes up to 15 kV. |
From an industrial design standpoint, polydomes eliminate tactile degradation caused by foreign particulate ingress. In harsh manufacturing spaces across Kaunas County—such as wood processing plants, chemical mixing facilities, and metal fabrication workshops—fine particulates can migrate beneath loose metal domes if perimeter seals fail. Polydome designs feature no free-floating metal parts, completely mitigating internal abrasion and contact shorting.

Frequently Asked Questions: Sourcing to Kaunas, Lithuania
Direct answers for Baltic procurement managers, system integrators, and quality assurance engineers regarding trade, testing, tooling, and shipping.
What are the typical shipping lead times and routes from Ningbo to Kaunas?
For rapid prototyping and time-sensitive NPI (New Product Introduction) batches, we ship air express via DHL/FedEx directly to Kaunas Airport (KUN) or Vilnius Airport (VNO) within 4 to 6 business days. For volume manufacturing orders, multimodal ocean freight enters the Port of Klaipėda (Lithuania) with scheduled overland transit to your Kaunas FEZ warehouse in approximately 28 to 34 days.
Can we order prototypes with an initial MOQ of 1 to 5 pieces before full commitment?
Yes. We actively support Baltic hardware startups, R&D engineering centers, and industrial design incubators with sample prototype runs starting from just 1 piece. We provide laser-cut tooling options for early mechanical fit validation, preventing steep tooling fees prior to freezing your final PCB layout and enclosure CAD files.
How do you prevent silver migration and contact oxidation in humid industrial environments?
Silver migration is caused by moisture and DC electrical bias between adjacent traces. We eliminate this failure mode by printing a continuous, pinhole-free carbon or dielectric overcoat over all silver conductors, maintaining minimum trace pitch design guidelines (≥0.5 mm), and applying perimeter moisture barriers with 3M high-cohesion acrylic adhesives to guarantee IP67 hermetic isolation.
Which design files do your R&D engineers require to execute a complete DFM review?
We accept CAD drawings in DXF, DWG, STEP, or vector graphic formats (Adobe Illustrator .AI or vector .PDF). Please include your circuit netlist or pin-out diagram, key actuation force specifications, color requirements (Pantone Solid Coated or RAL standards), connector specifications (e.g., 2.54 mm Nicomatic / FCI female housing, or ZIF flex pitch), and designated adhesive series.
Do you provide custom backlighting for low-light industrial machinery interfaces?
Absolutely. We incorporate three primary backlighting technologies: ultra-thin Light Guide Film (LGF) paired with high-efficiency edge-emitting LEDs, discrete embedded SMD surface-mount LEDs mounted within spacer cavities, or Electroluminescent (EL) foils. We perform photometric illumination simulations to guarantee color consistency (±5% Delta-E) and eliminate dark key edges.
What Incoterms and European payment terms are supported for Lithuanian buyers?
We support DDP (Delivered Duty Paid Kaunas warehouse), DAP, CIF, FOB Ningbo, and EXW terms. For financial transactions, we process payments via Wire Transfer (T/T), Letter of Credit (L/C), D/P, or Western Union in EUR, USD, and GBP currencies. Full commercial invoices, packing lists, CE declarations, and Certificates of Origin (CO) are provided alongside every export batch.
