APEM FD Push Button

FD Series Double Icon Illuminated Push Button

FD series, double icon illuminated push button switches, the combination of attractive design & robustness.

With two different legends on a single switch, the FD series is ideally suited for integrated designs where additional switches or indicators are no longer necessary.

Designed like a traditional push button, the FD series integrates a technology of superposed filters reacting to green and red light only. This technology allows the display of two different legends depending on the illumination colour.

MAIN FEATURES

  • Quality of screen printed legends
  • Uniform luminosity without hot spot
  • Large size, snap-in and threaded bushing versions
  • Sealing up to IP69K
  • Resistance to shocks and vibrations
  • Three standard legends are available. Additional legends can be achieved on request
