FD Series
Double Icon Illuminating Pushbutton Switches.
The FD Series, double icon illuminated pushbutton switches, are a combination of attractive design and robustness. The FD series is ideally suited for integrated designs where additional switches or indicators are no longer necessary. The FD series integrates a technology of superposed filters reacting to green and red lights only. This technology allows the display of two different legends depending on the illumination color.
Main Features:
- Quality of screen printed legends
- uniform luminosity without hot spots
- 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).
