Claim 16:
17. A power tool comprising:
a trigger assembly including:
a trigger shoe configured to be actuated in a first linear direction, wherein actuation of the trigger shoe moves a movable plunger in the first linear direction,
a movable arm configured to convert linear movement of the movable plunger into a rotational movement of the movable arm in a first rotational direction, the movable arm further configured to rotate an annular magnet coupled to the movable arm in the first rotational direction, and
a magnetic sensor configured to sense a first parameter of a magnetic field generated by the annular magnet, wherein the magnetic sensor is configured to convert the magnetic field to an output voltage representative of a position of the trigger shoe; and

a controller configured to receive the output voltage from the magnetic sensor and control an output of the power tool based on the received output voltage.
