1. A sensor system, comprising:
a magnet arranged such that:
a linear position of the magnet corresponds to a position of a trigger element on a substantially linear trajectory, and
an angular position of the magnet corresponds to a selected position of a selection element, the selected position being one of a plurality of selected positions; and
a magnetic sensor to:
determine the position of the trigger element based on a strength of a first magnetic field component and a strength of a second magnetic field component,
determine the selected position of the selection element based on a strength of a third magnetic field component and the strength of the second magnetic field component,
wherein the first magnetic field component, the second magnetic field component, and the third magnetic field component are perpendicular to each other; and
output, based on determining the selected position, a signal associated with the selected position.
