A human-machine interface comprises a return mechanism for returning a utensil to its neutral position. The return mechanism comprises a rocker suspended on first and second springs. This rocker is rotatable about a second axis and comprises first and second side-wings that are each situated on a respective side of a median plane containing a first axis about which the utensil rotates. These first and second side-wings comprise first and second regions for accommodating one end of the first and second springs, respectively, the orthogonal projection of the second accommodating region, in a plane containing the first and second axes being situated entirely between the first and second axes.

Human-machine interface

A human-machine interface comprising: —a magnetic rocker rotatably movable between a rest position wherein an implement is maintained in a neutral position and a tilted position wherein the implement is in a reclined position, —a magnetic assembly, attached to a frame, capable of cooperating with the magnetic rocker to generate a magnetic return force that constantly urges the magnetic rocker towards its rest position, —a sliding connection comprising a flange and a slide, and —the implement comprises one of the slides, and the flange and the magnetic rocker comprise the other of the slide and the flange such that the sliding connection transforms the movement of the implement towards the reclined position by moving the magnetic rocker towards its tilted position and vice versa.

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.

The monitoring module comprises a first transistor comprising a first and a second power electrode and a control electrode, the first and the second power electrodes of the first transistor being electrically connected to the second power 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 power supply cable so that the loss of first potential on the first power supply cable, caused by the interruption thereof, automatically triggers the switching of the first transistor to the closed state thereof.

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|F| and 1.1|F|, wherein |F| 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.

A solid-state switch according to the invention is designed to be connected in series with a load. The switch comprises at least two electric switching means connected in parallel, measuring means designed to measure an electric voltage at the terminals of the electric switching means and a main current flowing in the load, and control means delivering a control signal to act on opening and closing according to the value of the main current. The state of conduction of the first electric switching means depends at the same time on the main current flowing in the load, on a control current, on a control voltage delivered by the control means, and on the gain of the first electric switching means.

High-voltage solid-state switch

The invention relates to an electric arc detection device comprising analyzing means supplying current and voltage integration signals. The analyzing means supply current and voltage differential signals. Decision-making means comprise a disable unit supplying adaptive disable signals and comprising detection means supplying at least one decision-making aid signal according to at least one adaptive disable signal and to the current differential signal or the current integration signal. A decision-making unit supplies a trip signal according to the decision-making aid signals.

An on-board circuit breaker that includes a push-button that enables the circuit breaker to be reset by depressing it, a power supply terminal and distribution terminal, two breaking contacts, and a main bimetal strip. Thermal deformation of the main bimetal strip trips the circuit breaker. The circuit breaker further includes an actuator able to trip the circuit breaker and an electronic circuit monitoring the electric signal. The electric signal is monitored to trip the actuator when predefined particular situations are identified. The circuit breaker also includes a movable reset enable part equipped with a pin. When the circuit breaker is tripped, the reset enable part moves in such a way that resetting the circuit breaker is possible only by depressing the reset enable part before or when the push-button is depressed.
