An Impulse wrench includes: a housing, a motor with a stator and a rotor, an impulse unit including an output shaft, a power control unit connected to the motor, and a trigger supported on the housing and connected to the power control unit and arranged to selectively deliver signals to activate the power control unit, wherein the impulse unit including the output shaft is axially displaceable in relation to the housing. The trigger includes a sensor arranged to be activated and deliver signals in response to axial displacements of the impulse unit including the output shaft relative to the housing, and the power control unit is arranged to control the motor operation in response to signals received from said sensor. |
