メタルドームの触覚フィードバック
メタルドームフィードバックを備えた触覚メンブレンスイッチ
ドームの力、移動量、クリーンルームへの配置、バッチ間のクリックの一貫性を中心に構築されたカスタム触覚メンブレン スイッチ。
タクタイル メンブレン スイッチは、2 つのプリント回路層の間にあるステンレス鋼の金属ドームからクリック フィードバックを受け取ります。フォース、トラベル、クリックの音量は、オーバーレイ グラフィックではなく、ドームの形状によって決まります。
Quick answer: a tactile membrane switch gets its click feedback from a stainless-steel metal dome. When the overlay is pressed, the dome collapses past its buckling point, sends a snap through the keypad, and closes the contact below. The dome geometry sets force, travel, and click loudness.
目を離しても操作できるように設計
報道陣が登録していると感じる必要があるオペレーター向け
Forklift drivers wearing gloves, surgical-tower technicians, factory operators tracking a moving line, and field-test crews cannot always look at a display to confirm input. We build tactile membrane switches so the key press itself sends a consistent confirmation pulse through the operator’s fingertip.
クリーンルームでのドームの配置と 100% の導通テスト
JASPER は、ISO 14644-1 に基づくクラス 10,000 / ISO 7 クリーンルーム内に 304 ステンレス鋼のドームを配置し、PET とポリカーボネートのスタックをラミネートし、エッジをシールし、出荷前に IPC-A-610 許容基準に基づいて各ユニットのすべてのキーの導通をテストします。
触覚デザインのオプション
組み立て後のクリック感をコントロールする6つの選択肢
タクタイル メンブレン スイッチは、独立した設計上の選択肢の積み重ねです。 6 つすべてを指定すると、組み立てられた力が最初の承認サンプルから漂流するのではなく、生産を通じてサンプルの感触を維持できます。
ドーム型
4 脚、三角形、および 1 脚の形状の 304 ステンレス鋼のドーム。 4 脚のドームにより、最長の耐用年数と最も均一なスナップ感が得られます。
キーの形状
デフォルトは Ø 8 ~ 20 mm の丸キーです。スペーサーの形状によりドーム バインディングが妨げられる場合は、正方形、長方形、およびカスタムのダイカット キーがサポートされます。
回路層
PET フレックス フィルム上の銀インク トレース (テール ピッチ 1.0 mm、1.27 mm、および 2.54 mm)。ハイブリッド FR-4 PCB キャリアが利用可能です。
オーバーレイ
ポリカーボネートは、工業用手袋をしたまま使用する場合のデフォルトです。ポリエステルは、低コストでより精細なグラフィックスをサポートしますが、親指の摩擦が繰り返されると摩耗が早くなります。
Feedback level
Actuation force is 100–600 gf and travel is 0.2–0.6 mm. Tall four-leg domes create an audible click; low-profile domes reduce noise.
Protection rating
Sealed designs ship at IP65 or IP67 per IEC 60529 using a perimeter gasket plus a laminated overlay edge. EMI shield foil is optional.
| Dimension | Range we tool to | Default if you do not specify |
|---|---|---|
| Dome force | 100–600 gf | 250 gf, 4-leg |
| Travel distance | 0.2–0.6 mm | 0.4 mm |
| Key diameter | Round Ø8–20 mm | 12 mm |
| Tail pitch | 1.0 / 1.27 / 2.54 mm | 1.0 mm |
| オーバーレイ material | PC / PET | Polycarbonate, matte |
| Sealing | None / IP65 / IP67 | None, open back |
| Cycle endurance | Up to 1,000,000 per key | 1,000,000 |
Layer stack
The dome is only one part of the tactile system
The click you feel after lamination depends on the metal dome, overlay pre-load, emboss height, spacer adhesive, circuit support, and mounting flatness. That is why we validate the fully assembled keypad instead of relying only on a loose-dome datasheet.
Dome material for repeatable buckling and snap-back.
Class 10,000 / ISO 7 cleanroom dome placement.
IP65 / IP67 gasket sealing when specified.
Sinusoidal vibration testing on application request.
Readable tactile stack
Each layer changes the force the operator feels after lamination.
Design considerations
Where tactile specs slip before tooling
The actuation force measured on a loose dome is not the force the operator feels after the keypad is laminated, mounted, and used with the final overlay.
Loose vs assembled force
Loose-dome readings typically run 15–25 gf higher than assembled keypad force because overlay pre-load, spacer adhesive, and emboss geometry shift the dome before the operator presses it.
Emboss depth changes snap
A 0.3 mm emboss over a 250 gf dome can feel firmer than a flat overlay over a 350 gf dome. We set emboss height during design review.
Mounting flatness matters
A keypad bonded to a panel that bows by 0.5 mm across a 200 mm span will read different forces in the center and corners.
Spec-to-sample loop
Validate the assembled feel before production tooling
You send a target such as 250 gf actuation, 0.4 mm travel, and audible click. We build five fully laminated samples before cutting tooling, your team measures and presses, and we adjust dome geometry if the felt force is high or low.
- 01Send dome force, travel, key layout, overlay material, and protection rating.
- 02JASPER reviews the stack, emboss, circuit, tail pitch, and sealing plan.
- 03We build five laminated samples to the target spec.
- 04Your team presses and measures the assembled keypad.
- 05The loop usually closes in two iterations and about ten working days.
Typical uses
用途 where operators need tactile confirmation
Forklifts and off-highway vehicles
Gloved operators need confirmation without looking away from the road, load, or work area.
Medical equipment
Surgical-tower and diagnostic-device controls need repeatable snap with sealed, wipe-clean overlays.
Factory automation
Line operators press keys while watching a moving process instead of a display confirmation.
CNC and industrial controllers
IP-rated tactile keys resist dust, vibration, and repeat actuation in shop-floor environments.
Mobile diagnostic equipment
Field instruments need compact sealed interfaces with dependable key feel.
Packaging and mining machinery
IP65/IP67 variants handle washdown, dust, and vibration better than exposed PCB tactile switches.

FAQ
Frequently Asked Questions
What is the difference between a tactile and non-tactile membrane switch?
A tactile membrane switch contains a metal dome that physically collapses when pressed and snaps back when released. A non-tactile membrane switch is a flat printed circuit with no dome; the operator relies on a beep, LED, or screen update.
Can the dome force be customized on a tactile membrane keypad?
Yes. Leg count, dome height, and stainless-steel thickness set actuation force. Standard catalog domes include 150 gf, 250 gf, and 350 gf; custom 100–600 gf forces are available in 25 gf increments with an MOQ of 5,000 units per value.
Is a tactile membrane switch suitable for industrial vibration environments?
Yes. The 304-stainless-steel dome plus laminated PET stack resists vibration-induced false actuation. On request, we test assembled keypads to IEC 60068-2-6 and build IP65/IP67 variants per IEC 60529.
