Illuminated Pushbutton Switches for Aerospace Cockpit Panels: Selection and Integration Guide
The Role of Illuminated Pushbutton Switches in Modern Cockpits Modern glass cockpits and industrial HMI consoles demand more from pushbutton switches than simple on-off control. An illuminated pushbutton switch combines three functions in one sealed assembly: a mechanical switch mechanism for circuit transfer, an LED indicator for unambiguous status feedback, and a human-readable display surface for customized legends and symbols. The integration of these functions eliminates separate indicator lamps, reduces panel wiring complexity, and improves mean-time-between-failure (MTBF) by removing interconnect failure points. ...
