Esterline has engineered its Korry 389 5/8-inch LED switch for human machine interface (HMI) applications where superior lighting performance, product reliability, and system versatility are required. Its innovative circuitry design has earned the company several patents.

  • Surface-mounted electronics with the latest generation of high-brightness LEDs
  • Uncompromising performance in system interface capabilities
  • Exceptional illumination characteristics such as brightness output and dimming control
  • Versatile circuit card assembly (CCA) design for any type of dimming requirement
  • Mechanically interchangeable with most 5/8-inch switch products

See below for additional information and an overview of your various ordering options. In addition to the 389 series, our 427/428 switch — precursor of the 389 series — is still available.
