else is in an intermediate position the invention is not limited to the particular embodiment described above but on the contrary covers any variant coming within the ambit of the invention as defined by the claims although a particular number of angular position detectors are detected above and although these detectors are selected to be made using a particular technology based on contactors and although a particular technology has been selected for the actuators it is possible to provide for some other number and to use other technologies for example it is possible to use a hall effect angular position sensor with the magnet of the sensor occupying the shaft in such a manner as to interact electromagnetically with the detector regardless of the axial position of the shaft 14 similarly the general shape of the shaft and the relative positions of the elements in the cavity may be different providing a portion of the shaft is suitable for co operating with the angular position detector although in this example the control box incorporates a processor for communicating with an external electrical unit it is possible to provide for the processor and the external electrical unit to be incorporated in the control box or else in external equipment it is also possible for the position of the shaft to be acquired and or for orders to be transmitted in some other way e g mechanically although the control box described is for operating a landing gear hatch from the ground it is possible to use the control box in any other application finally although the safety actuation.
