Switch device

A switch device, comprising:

• a movable body that is displaced in an axial direction in conjunction with an operation of an operated portion;
• a magnet provided on the movable body;
• and
• a plurality of magnetic force sensors arranged facing the magnet;
• wherein the plurality of magnetic force sensors includes a first magnetic force sensor with a detection surface facing the magnet and a reversed second magnetic force sensor with a detection surface facing away from the magnet;
• wherein a total number of the plurality of magnetic force sensors is at least three;
• wherein the magnet is attached to a portion of the movable body facing the plurality of magnetic force sensors;
• wherein the magnet has a width in a first direction orthogonal to the axial direction as viewed from the axial direction;
• wherein the plurality of magnetic force sensors are arranged in the first direction such that the plurality of magnetic force sensors are aligned with one another relative to the axial direction and are disposed a same distance from a surface of the magnet;
• wherein the magnet is arranged in a magnetic pole orientation in which one side in the axial direction is an N pole and the other side is an S pole;
• and
• wherein the plurality of magnetic force sensors are positioned in the axial direction such that the plurality of magnetic force sensors face a first magnetic pole of the magnet when the operated portion is not operated and face a second magnetic pole of the magnet when the operated portion is operated.
