  • Illuminated switch or indicator with integral data communications device and fail sense function
    Patent number: 10388470
    Abstract: An aircraft annunciator (illuminated switch or indicator) includes, within a housing sized to fit in the panel cutout for a single pushbutton aviation switch, a bus converter to interface with a multiplexed ARINC serial data bus, in order to monitor a remote item of equipment such as an ADS-B transponder. The annunciator is coupled by selected pins to receive data words from the multiplexed ARINC serial data bus. A watchdog timer is continuously reset by valid messages from the transponder, logically ORed with the power supply as well as external analog fault signals in order to generate an output controlling illumination of an FAA-mandated “ADS-B FAIL” legend on the annunciator.
