Claim 18:
19. A power tool comprising:
a tool attachment,
an elongated body,
a first handle portion attached to the elongated body,
a power source arranged to power the tool,
a second handle portion attached to the elongated body and comprising a throttle lever,
a circuit board located in a sealed enclosure,
a human machine interface comprising components arranged on and adjacent a first side of the circuit board,
a magnet operably connected to the throttle lever, wherein the magnet is moveably arranged along an arc in response to a displacement of the throttle lever, and
a sensor arrangement configured to sense an intensity of a magnetic field of the magnet, wherein the sensor arrangement is arranged on and adjacent a second side of the circuit board,
wherein the magnet is located outside of the sealed enclosure and movably arranged along a travel path,
wherein the sensor arrangement comprises at least two sensors each configured to sense the intensity of the magnetic field of the magnet, wherein the at least two sensors are arranged in a first plane substantially perpendicular to the travel path, and wherein an angle between two adjacent sensors of the at least two sensors, measured in the first plane at a point coinciding with the travel path of the magnet, is approximately 90 degrees or 120 degrees.
