US Patent 11883944 Actuator arrangement for a power tool

A handheld power tool includes an actuator arrangement, which includes a movable trigger member and a sensor arrangement. The trigger member includes at least one magnetic element, and the sensor arrangement is responsive to a displacement of the magnetic element along with the movable trigger member relative to the sensor arrangement. The sensor arrangement includes an analog magnetic field sensor configured to provide a signal proportional to the position of the magnet, a first digital magnetic field sensor configured to provide a first digital switching point in response to the position of the magnet, and a second digital magnetic field sensor configured to provide a second digital switching point in response to the position of the magnet.
