Beschreibung
Zusammenfassung:	A lawnmower comprising a housing, one or more cutting blades, and a motor configured to rotate the one or more cutting blades. The lawnmower includes a handle including a switch assembly. The switch assembly includes a contactless switch pivotable about an axis point and a magnet located at the axis point. One or more paddles extend from the handle. The rotation of the one or more paddles causes the contactless switch to pivot about the axis point. The lawnmower includes a sensor configured to sense a variation of a magnetic field of the magnet, and a controller coupled to the motor and the sensor. The controller is configured to receive, from the sensor, a value associated with the variation of the magnetic field of the magnet, and control the motor based on the value of the variation of the magnetic field.
