| 摘要 |
A device for detecting the state of a switch. The device includes a detection circuit which delivers a signal of specified value (Vpullup) when the value of an electrical quantity (RSw) characterizing the state of the switch is less than a threshold called the lower threshold (Rclosed) and/or a signal of different value when the value of the electrical quantity is greater than a threshold different from the lower threshold, called the upper threshold (Ropen). The disclosed embodiments also concern flight control systems, in which the device is implemented, and the aircraft including the systems.
