Contoured HMI Solutions

3D-Keys Keyboards

Advanced keyboards featuring thermoformed 3D contoured keys and raised borders. By embossing high-grade polyester overlays using heat and pressure, we create tactile finger-guides that allow blind orientation and comfortable typing ergonomics, sealed up to IP67.

Key Features

Three-dimensional key sheets with complete liquid barriers

Designed to deliver tactile references, custom shape profiling, and chemical resistance for clinical and defense sectors.

Contoured 3D Keys

Thermoformed overlays provide raised key rims, pillow surfaces, or custom finger recesses, enhancing tactile ergonomics.

Blind Touch Navigation

Raised key boundaries allow users to feel key positions and orientation without visual checks, which is essential for low-light cabins.

High Shape Retention

Uses thermal forming on premium Autotex polyester films, ensuring the 3D shapes maintain height over 2 million activations.

Absolute Fluid Sealing

The continuous embossed overlay forms an unbroken front skin, preventing water, dust, chemicals, and sanitizers from penetrating.

Tactile Snap Domes

Houses gold-plated stainless steel domes underneath to deliver a crisp tactile snap ratio with high electrical contact reliability.

Sub-Surface Legends

Graphics and key labels are screen-printed on the underside of the clear overlay, protecting them from cleaning agents and abrasion.

Thermoformed HMI Skin

Contoured finger guides and absolute environmental isolation

Keetronics 3D-Keys keyboards bridge membrane convenience and tactile orientation. By thermoforming durable polyester overlays into precise 3D relief structures-including pillow embosses, raised borders, and customized shape guides-we provide operators with instant physical reference. Graphics remain protected underneath the watertight polyester shield, offering a sanitary, robust interface for clinical devices, industrial machinery, and field controls.

  • Raised borders or pillow keycaps created via heat-press embossing
  • Unbroken graphic overlay skin achieving complete IP67 sealing
  • Reliable contact feedback using underlying stainless steel snap domes
  • Resistant to industrial chemicals, petroleum solvents, and alcohols

FORM
3D Thermoforming

Heat and pressure embossed profiles creating raised boundaries or button shapes directly on the top film.

PETF
Autotex Polyester

High-tensile polyester film chosen for its excellent flexing life, chemistry barrier, and shape retention.

DOME
Metal Dome Chamber

Internal cavity beneath each embossed dome that houses a stainless steel dome for click response.

TRAC
Silver Trace Network

Conductive screen-printed silver ink traces that route switch closure signals to the FPC connector tail.
