Interface Feedback Solutions

Tactile & Non-Tactile Keyboard

Custom-engineered membrane keyboards designed with either clicky tactile switches (utilizing metal or polyester domes) or flat, zero-travel non-tactile switches. Tailored for clinical cleanrooms, heavy machinery controls, and remote terminals to balance finger guidance with sanitization and long operational life.

Key Feedback Customization

Crisp mechanical click snap versus flat clean wipes

Designed to support medical operators seeking wipe-down surfaces and industrial operators requiring physical key click recognition.

Crisp Tactile Domes

Uses high-grade stainless steel or embossed polyester domes to give a distinct snap feeling (0.3mm to 0.6mm travel) upon key activation.

Flat Non-Tactile Design

Completely flat front panels with no moving components. Relies on conductive circuit contact without click travel, maximizing sealing integrity.

Hygienic Cleanroom Surface

Non-tactile keyboards offer an entirely flat surface with no embossing or gaps, facilitating total sterilization in medical and food lines.

Sub-Surface Printing

Legends are reverse printed on polyester or polycarbonate foils. Text, borders, and brand icons never scratch or fade even with intensive cleaning.

Extended Switch Lifespan

Non-tactile switches support up to 5-10 million operations because they have zero mechanical fatigue, whereas metal domes sustain 1-3 million clicks.

Tailored Actuation Forces

Customize key press weights from light forces (1.5N) for rapid data entry to heavy forces (4.0N) to avoid accidental actuation on naval bridge panels.

Key Feedback Integration

Tactile snap versus zero-travel clean panels

We help you select the exact feedback profile for your operators. High-vibration vehicle cabins need metal domes with strong snap feedback to guarantee inputs are registered, while food manufacturing processing lines require flat, non-tactile panels to allow easy washdowns without debris collecting in key crevices.

  • Embossed key borders (pillow, rim, or dome shapes) for finger guiding
  • Integrated LEDs under key windows for non-tactile status indication
  • Chemical-resistant textured coatings (anti-glare, anti-microbial)
  • Direct connection matrix, USB, or custom microcontroller interfaces

TAIL
FPC Tail & ZIF Connection

Flexible printed tail with standard pitch connectors (2.54mm or 1.0mm) for simple card-slot installation.

FIRM
Debouncing Firmware

Controller boards use firmware debouncing to ensure clean signals, especially when metal domes snap.

WIND
Window Backlighting

Clear transparent window sections allow internal LEDs to light up, indicating switch activation on non-tactile panels.

ESD
Internal Ground Shield

An integrated polyester sheet with conductive ink routes static discharges directly to the grounding chassis.
