Abstract
Portable electric tool including a body configured to act as a handgrip and at one of the ends of which there is mounted a moving active member, the movements of which are brought about by an actuator, characterized in that the moving part is equipped with an oriented magnetization magnet that can be moved past a magneto-resistive sensor fixed to a fixed element of the body. The trigger is equipped with an oriented magnetization magnet that can be moved past a magneto-resistive sensor fixed to a fixed element of the body. The portable electric tool further includes an electronic board for analyzing the information emitted by each magneto-resistive sensor according to the inclination of the magnetic field lines presented to it, in order to control the operation of the actuator so as to position the moving part accurately according to the position of the control device.
