A redundant and dissimilar system for monitoring the status of contactors of an aircraft control stick. This monitoring system comprises at least one electrical power source, at least one processor and several circuits for monitoring the status of the switches of the contactors. Each monitoring circuit comprises and electrical power source, a switch for each contactor, the switches of a contactor being connected to each other, and an electronic assembly provided with receivers arranged in series with each other. Each switch is arranged in parallel with at least one receiver so as to short-circuit the at least one receiver when the switch is in the closed state. Each processor measures and analyses an electrical feature of the electronic assembly, such as a mains voltage VE as the terminals of the electronics assembly, in order to determine the status of each switch.

A haptic device comprising a base and at least one shaker branch. Said at least one branch is connected to the base by mobility means conferring a degree of freedom on the branch to move in rotation about a pivot axis relative to the base. An exciter member comprises electrical exciter means configured to cause said at least one branch to shake by moving in rotation about the pivot axis from a rest position to an activated position, and resilient return means tending to maintain each branch in the corresponding rest position.
