Abstract
An annunciator panel for aircraft has a plurality of pockets defining individual illuminated indicator devices. A lens assembly comprising a plastic lens and glass filters bonded together is encompassed by an elastically stretched rubber sleeve having an integral flange compressed between the lens body and panel housing, providing a light, fluid and particulate seal between lens and housing as well as a vibration and shock buffer to the lens and filters. The resiliency of the rubber sleeve accommodates different thermal expansion between dissimilar materials without imparting damage stresses to the lens assembly.
