  • Built-in test system for aircraft indication switches
    Patent number: 6593758
    Abstract: A built-in test system for aircraft indication switches comprises a plurality of aircraft indication switches and a first resistor adding network having input resistors individually connected to first contacts of different ones of the indication switches. The test system further includes a second resistor adding network having input resistors individually connected to second contacts of different ones of the indication switches. Output circuitry is provided for coupling outputs of the first and second resistor adding networks to an electronic control unit for the aircraft.
    Type: Grant
