Mid-Travel Switch - Esterline Interface Technologies

Product Description

Elastomer Plastic Key Technology

Advanced Input Systems' Mid-Travel (1-2mm) keyboards are designed for harsh environments. Keytops are available in plastic, rubber or metal, depending on the application, look and feel desired. Mid-Travel keyboards are typically sealed, and water-resistant. We can create any conceivable keyboard—design, size, composition, color, lighting, technology—in this series.

Typical Applications

Industrial input
Point-of-sale systems
PBX controls
Process control equipment
Office equipment
Banking terminals
Medical equipment
Kiosks
