防水メンブレンスイッチと密閉型コントロールインターフェース
オーバーレイ、エッジ、テール出口、接着剤、ハウジング、検証済みテストなど、1 つのシステムとして設計された密閉型コントロール パネル。
当社は、船舶用ヘルム、屋外用ハンドヘルド、医療用洗浄装置、産業用ペンダント ステーション、食品グレードのパネル、およびフィールドサービス ツール用の防水メンブレン スイッチを製造しています。
防水は素材ではなくシステムです
メンブレン スイッチの防水はシステムであり、材料、単一の IP 定格、最後にボルトで取り付ける層ではありません。
アセンブリ上の 6 つの場所 (前面、エッジ ラミネート、テール出口開口部、感圧接着剤、ハウジング インターフェース、シールを証明するテスト プロトコル) には浸水のリスクがあります。 5 つ修正して 1 つをミスすると (ほとんどの場合、最後尾の出口です)、スイッチはベンチでは IP67 に合格しますが、フィールドでは不合格となります。 JASPER Electronics では、6 つすべてを同じ図面パックで設計し、その結果を IEC 60529、NEMA 250、およびアプリケーションが要求する場合は MIL-STD-810H Method 506.6 に照らして検証します。
What keeps those switches alive after twelve months in salt spray or 80 °C hot-water steam is not the polyester — it is how the six pieces fit together. Our engineering team works from your STEP and 2D PDF housing files, returns a marked-up drawing within 24 hours, ships a first-article sample in 7–14 working days, and supplies a test report referencing the exact standard your buyer needs. PPAP submissions are available on request for IATF 16949-regulated programmes. For deeper background on the underlying physics, see our waterproof membrane switch design guidance.
Quick Answer
メンブレンスイッチの防水機能は何ですか?
メンブレン スイッチは、ハードコートされた PET オーバーレイ、熱ラミネートされたエッジ ボンド、ポッティングまたは熱かしめされたテール出口、浸漬定格のアクリル PSA、ハウジングに対する圧縮性ガスケット、および IEC 60529 サブ条項 14.2.7 に対する検証済みテスト (1 m の真水で 30 分間) の 6 つの要素が一緒に設計された場合にのみ IP67 に達します。エンジニアリングシールのないベア PET-on-PCB スタックは、通常、IP54 のみです。 6 つのうち 1 つでもミスすると、そのパートがベンチを離れた時点で評価は維持されません。
6つの防水設計要素
水は 6 つの界面のうち最も弱い界面を見つけます。部品を描画する前に、6 つの工学的な質問に答えます。
防水メンブレン スイッチは、オーバーレイ、接着剤、回路、スペーサー、背面接着剤の積層体がハウジングに固定されたものです。以下の 6 つの要素はそれぞれ 1 つの入力パスを閉じます。
1. 前面をシールします。
前面層はハードコートされた PET オーバーレイ (通常は Autotex F200 または同等の耐摩耗性グレード) で、第 2 面にスクリーン印刷されているため、インクとグラフィックがシールの下に収まります。エンボスキーはハードコートに亀裂を入れてはなりません。そのため、エンボスの高さを 0.18 mm PET 上で 0.6 mm に制限し、100 サイクルのフレックス プレスクリーンを実行します。 IP69K ウォッシュダウン サービスの場合、ハウジングの図面に 1.0 ~ 1.5 mm のベゼル オーバーハングを追加し、80 ~ 100 bar のスチーム ジェットをオーバーレイの端から逸らします。
2. 端をシールします。
オーバーレイと回路のエッジは、連続的な水への暴露に耐えられると評価されたアクリル PSA 層を介して熱ラミネートされています。 PSA ショルダーがウィッキングにさらされないように、オーバーレイを回路フットプリントの 0.2 mm 以内で同一平面にトリミングします。ブイに取り付けられたセンサーや水没ドック コントローラーなどの IP68 連続浸漬用途の場合、スイッチをハウジングに 0.3 mm 埋め込み、第 2 の防御線としてベゼルの溝にシリコン ビーズを配置します。
3. テール出口を密閉します。
ラミネートから離れたフレックス回路テールは、ほとんどの防水メンブレン スイッチが現場で故障する箇所です。毛細管現象により、湿気が尾部を通ってハウジング内に引き込まれます。当社はこれを 2 段階でシールします。オーバーレイ端でテールの周囲に熱かしめ PET カラーを成形し、次にハウジング出口スロットに硬化エポキシ ポッティング ビードを取り付けます。テール幅はスロットに ±0.1 mm 以内で一致します。サービス交換可能なアセンブリとして、IP67 等級のシリコングロメット出口を提供しています。これがお客様をスキップさせない要因です。
4. 接着剤を選択する
We standardise on 3M 467MP and 3M 468MP acrylic transfer adhesives for the internal layers — 0.05 mm and 0.13 mm thick respectively, peel strength ≥18 N / 25 mm on stainless, service range −40 °C to +90 °C. For high-load housing bonds where the switch is the gasket, we specify 3M VHB 4910 or 5952. We size the footprint to leave a 1.5 mm exposed border so the laminate does not see squeeze-out at the edge. See our materials and adhesives reference for the full PSA-by-application chart.
5. ハウジングとの嵌合
The seal between the membrane assembly and the bezel is a compressible gasket — Poron microcellular urethane for general-purpose IP65 to IP67 mounting, or 60-Shore-A silicone for IP68 and IP69K. We design the gasket to compress 25–40% in the finished assembly, keeping the seal active even after housing screws relax over a year of thermal cycling. The bezel mating surface must be flat within 0.1 mm per 100 mm of run. When EMI shielding is in the brief, we co-locate a conductive elastomer gasket in the same groove without compromising water resistance.
6. Test the seal
We test against the standard the customer’s certifying body will recognise. IEC 60529 IPX7 drops a sealed unit into 1 m of fresh water for 30 minutes; IPX8 extends to continuous immersion at an agreed depth and duration (typical marine spec is 1.5 m for 24 hours). IP69K, defined by ISO 20653, runs four 80 °C, 80–100 bar steam jets at 30 seconds per position. North American buyers also recognise NEMA 250 Type 4 and Type 4X. For blue-water marine and rugged handhelds we add MIL-STD-810H Method 506.6 rain-test and IEC 60068-2-31 drop-test sequences. Every shipment includes the relevant test report.
The sealed stack
Five laminated layers, clamped into the housing, with every interface engineered against water.
A waterproof membrane switch is the sealed member of the membrane switches family. The overlay carries the seal, the printed circuit carries the contacts, and the adhesives, spacer, and gasket hold the ingress paths closed. Most projects also benefit from reviewing our membrane switch panels overview to see how the sealed stack integrates with the wider control-panel assembly.
Where chemistry compatibility is a question — solvents, fuel, surgical disinfectants — we run a 7-day immersion test on a coupon before we cut the production tool.
Verification standards
How we prove the seal before a part ships
A waterproof claim is only as good as the test behind it. We run the protocol the customer’s certifying body recognises and ship the report with every order.
IPX7 immersion
IEC 60529 sub-clause 14.2.7 — a sealed unit submerged in 1 m of fresh water for 30 minutes, the baseline for IP67 spill and splash duty.
IPX8 continuous
Continuous immersion at a depth and duration agreed with the customer; typical marine spec is 1.5 m for 24 hours for sub-deck and buoy hardware.
IP69K steam-jet
Per ISO 20653 — four 80 °C, 80–100 bar steam jets at 30 seconds per position, used for food-grade and dairy wash-down panels.
NEMA 250 & MIL-STD
NEMA 250 Type 4 / 4X cross-reference for North American buyers, plus MIL-STD-810H Method 506.6 rain test and IEC 60068-2-31 drop test for rugged units.
Application examples and recommended IP ratings
We ship waterproof membrane switches into seven recurring environments. The right IP level depends on what is hitting the surface — rain, hose, sustained immersion, or pressurised steam.
| Industry / Use | Typical product context | Recommended IP rating |
|---|---|---|
| Marine | Helm controls, deck panels, bilge-pump interfaces | IP67 above deck, IP68 sub-deck; MIL-STD-810H 506.6 for blue-water — see our marine applications page |
| Outdoor / Field | Handheld GPS, traffic-sign controllers, weather stations, EV-charger fronts | IP65–IP67 with UV-stable hard-coat overlay — see marine and outdoor applications |
| Medical | Infusion-pump fronts, dental-chair controls, dialysis-machine interfaces | IP67 for spill resistance; IP68 when sterilised by immersion — see medical device applications |
| Industrial control | Forklift consoles, conveyor HMIs, sealed pendant stations | IP65–IP67; NEMA 4 cross-reference for North America — see industrial control applications |
| Wash-down | Food-grade equipment, dairy, pharma cleanroom panels | IP69K per ISO 20653; stainless or anodised-aluminium bezel |
| Appliance | Kitchen ovens, washing machines, water-heater fronts | IP54–IP65; gasketed bezel mount sufficient — see home appliance applications |
| Handheld portable | Ruggedised radios, marine remotes, asset trackers | IP67 plus IEC 60068-2-31 drop-tested |

見積もりを依頼Waterproof membrane switch questions
Is every membrane switch waterproof? What makes one IP67?
No. A standard PET-on-PCB membrane stack with no engineered seal is typically rated IP54 — it resists splashes and dust, nothing more. A switch reaches IP67 only when six things are engineered together: a hard-coated PET overlay, a heat-laminated edge bond, a potted or heat-staked tail exit, an acrylic PSA rated for immersion, a compressible gasket against the housing, and a verified test against IEC 60529 sub-clause 14.2.7 — 1 m of fresh water for 30 minutes. Miss one of the six and the IP rating will not hold once the part leaves the bench. Our IP rating guide walks through each step in more detail.
How do I order a waterproof membrane switch for outdoor use?
Send us four things. First, the housing drawing in STEP plus a 2D PDF. Second, the duty cycle — rain, hose-down, sustained immersion, or wash-down with detergent. Third, the IP target and the certifying standard the end-customer needs (IEC 60529, NEMA 4X, ISO 20653, or MIL-STD-810H Method 506.6). Fourth, any LED backlighting, tactile-dome, or connector callouts. We return a marked-up drawing, a material BOM listing the overlay, PSA, gasket and tail seal by part number, a sample in 7–14 working days, and a test report citing the exact standard. Production lead time after sample sign-off is typically 4–6 weeks for tooling plus 2–3 weeks per order.
Can a waterproof membrane switch include LED backlighting and tactile keys?
Yes — neither LEDs nor tactile metal domes break the IP seal when they are integrated inside the laminate. SMD LEDs are reflow-soldered onto the flex circuit below the sealed top layer, so the light source sits behind the same overlay that carries the seal. Embossed polydomes or stainless-steel snap domes are placed under the overlay before lamination, which keeps the top surface continuous and crack-free. One design rule controls the trade-off: the combined dome height and light-guide thickness must stay inside the gasket compression envelope, typically 1.5 mm or less, so the bezel still closes uniformly on the housing gasket and the seal load stays in spec.
