  • Patent number: 4722028
    Abstract: A pushbutton switch having an illuminated display or other instrumentation data or control display device is made compatible both with unassisted night time vision of the display as well as vision assisted by a night vision imaging system or night vision goggles. The display is backed with a plurality of selectively activated light sources. Each light source is characterized by a spectral range. At least one of the light sources has a spectral range compatible with the night vision imaging system. At least another one of the light sources has a spectral range compatible with unassisted night vision. In the preferred embodiment, the light source is comprised of a conventional incandescent bulb disposed within a domed glass filter. The domed glass filter has a spectral transmissivity which is compatible with the night vision imaging system. In particular, the filter has a transmissivity approximately equal to either ANVIS Green A, ANVIS Green B, or Yellow.
