A device for detecting the state of a switch. The device includes a detection circuit which delivers a signal of specified value (V) when the value of an electrical quantity (R) characterizing the state of the switch is less than a threshold called the lower threshold (R) 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 (R). The disclosed embodiments also concern flight control systems, in which the device is implemented, and the aircraft including the systems.

Device for detecting the state of a switch

An engine speed control device includes an engine speed control lever that generates an engine speed instruction and a device for delivering the indicative information on the actual engine speed. An actuator applies a mechanical force on the lever according to the difference between the instruction and the indicative information on the actual engine speed.
