Contactless magnetic sensing trigger system

A device, comprising:

• a first element moveable along a first axis;
• a second element rotatable about or moveable on a second axis;
• a first magnet arranged such that a linear position of the first magnet represents a position of the first element with respect to the first axis;
• a second magnet arranged such that an angular position of the second magnet represents a selected position of the second element with respect to the second axis, the selected position being one of a plurality of selectable positions;
• and
• a magnetic sensor to:
• determine the linear position of the first 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 second element based at least in part on a strength of a third magnetic field component;
• and
• output, based on determining the selected position, a signal associated with the selected position.

A method, comprising:

• determining, by a magnetic sensor, a linear position of a first element based on a strength of a first magnetic field component and a strength of a second magnetic field component,
• wherein a linear position of a magnet corresponds to the linear position of the first element;
• determining, by the magnetic sensor, a selected position of a second element based on a strength of a third magnetic field component and the strength of the second magnetic field component,
• wherein an angular position of the magnet corresponds to the selected position of the second element;
• and
• outputting, based on determining the selected position, a signal associated with the selected position.
