摘要： A power tool includes a housing, an electric motor mounted in the housing, and a switching device for reversing rotation direction of the motor. The switching device includes an actuator slidably secured to the housing and movable between first and second positions. The actuator includes a magnet. A first ferromagnetic member is attached to a first housing section so as to be within range of attraction force of the magnet when the actuator is in the first position and a second ferromagnetic member is attached to a second housing section so as to be within range of attraction force of the magnet when the actuator is in the second position. A hall sensor is attached to the housing so as to be proximate the magnet as the actuator is moved between first and second positions. Proximity of the magnet and hall sensor reverses the direction of rotation of the motor.
