Abstract: The disclosure relates to an electrical installation comprising a monitoring module positioned between a sensor connected to a measurement cable and first and second supply cables for the sensor. The monitoring module comprises a first transistor comprising first and second power electrodes and a control electrode, the first and the second power electrodes of the first transistor being electrically connected to the second supply cable and to the measurement cable, respectively, so that when the first transistor is in the closed state thereof, a first fault value is generated on the measurement cable. The control electrode of the first transistor is connected to the first supply cable so that the loss of current in the first supply cable, caused by the interruption of the current, automatically triggers the switching of the first transistor to the closed state thereof.

Abstract: A joystick comprises an articulation comprising bearing faces that are shaped to permit, via shape-shape interaction when they rub against each other, a rotational movement of a handle. A first set of springs exerts, on the handle, a first vertical force that pushes the bearing faces against each other. A second set of springs exerts, on the handle, a second vertical force in the opposite direction to the first vertical force and the amplitude of which is between 0.9|F1| and 1.1|F1|, wherein |F1| is the amplitude of the first vertical force. The first and second sets of springs are able, in the absence of external stress on the handle, to maintain a non-zero clearance between all the bearing faces of the articulation.
