Key Features

Comfortable elastomer tactility with extreme seal protection

Designed to deliver exceptional click feedback, wear-proof backlighting, and fluid-resistant barriers for demanding control units.

Seamless Inherent Gasket

The continuous molded rubber top skin serves as a self-sealing cover that prevents water, dust, and oils from reaching the internal electronics.

Elastomeric Tactility

Designed with precision-engineered rubber webbing to deliver crisp tactile feedback, snap-ratio rebound, and travel ranging from 1.0mm to 2.5mm.

Reliable Contact Options

Integrates conductive carbon pills, gold-plated metal domes, or tactile micro-switches for reliable electrical contact closure.

Laser-Etched Backlighting

Translucent base silicone coated with opaque paint layers, laser-ablated for sharp backlight text and graphics in night setups.

Protective Wear Coatings

Coated with Polyurethane (PU), Epoxy, or Silicone sprays to ensure key marking text resists industrial solvents, cleaning agents, and high abrasion.

Sanitary & Spray Washable

Eradicates structural crevices and gaps, making it simple to spray-wash, sanitize, and disinfect in clinical or food processing sectors.

Silicon Rubber Keyboard Interface
Flexible Elastomer Panels

High-durability elastomer controls for rigorous interfaces

Keetronics silicone rubber keyboards combine tactile responsiveness with superior environmental defense. By molding the top skin as a single, contiguous elastic membrane, we create panels that function as their own sealing gaskets. Coupled with conductive carbon contacts or metal snap domes, these keyboards offer excellent click feedback and long life in cleanrooms, transport cockpits, and machinery desks.

  • Continuous silicone surface with no open slots to harbor dust or fluids
  • Laser-etched spray coating for brilliant, wear-proof backlighting
  • Tailored actuation force (1.0N to 3.0N) for precise tactile responses
  • Direct integration over mechanical switch arrays or PCB copper contacts

Elastomeric component layout

ELAS
Elastic Rubber Webbing

Specially tuned webbing profile providing the tactile snap and click feel, returning the key to its resting state.

CARB
Conductive Carbon Pill

Molded carbon-silicone contacts on the underside of each key that close the electrical loop upon compression.

COAT
PU Protective Spray

A double layer of matte polyurethane paint sprayed over the key legends to prevent print wearing under heavy usage.

BACK
FR4 PCB & Rigid Backer

Rigid backing plate supporting the elastomeric sheet, providing a solid counter-force for key presses.
