This sealed joystick for a machine comprises a function block, an outer shell formed by joining two rigid half-shells, these half-shells tightly enclosing the function block, each half-shell comprising a joint surface for this purpose all along its perimeter following a three-dimensional path which terminates on itself and which extends in the three dimensions of space, a sealing element comprising a one-piece block of elastomer material combining a sealing cord and a ring seal of different transverse cross-section within this same block to ensure that the joint surfaces are watertight.

The invention concerns a control wheel () for aeronautics constituted of at least two half-shells () assembled one to the other, said half-shells comprising reinforcing ribs () on their internal surface, positioning and fixing means () and locating holes () to allow the passage of electrical wires connecting electrical actuating means () to a control unit. The control wheel () includes a central opening () intended to be connected to a control shaft/hub. The wheel comprises an intermediate guide part () disposed between the half-shells () and positioned inside the control wheel (), said part including at least one guide conduit () adapted to connect on the one hand a locating hole () to the central opening () of the control wheel ().

Control wheel for aeronautics

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.
