PROBLEM TO BE SOLVED: To provide a switching device capable of suppressing deviation of boundary height positions between a lower contact point and an upper contact point of a change-over contact. SOLUTION: The switching device is provided with a control lever 2 housed in a case 1 in free rotation, a torsion coil spring 3 forming a movable contact equipped with a wound-around part 3a, a first arm part 3b, and a second arm part 3c, a fixed contact 5a in constant contact with the first arm part 3b of the torsion coil spring 3, and a changeover contact 6a equipped with a lower contact part and an upper contact part capable of compression holding the second arm part 3c of the torsion coil spring 3 and separating the second arm part 3c at bending deformation of the second arm part 3c accompanying rotation of the control lever 2. The lower contact part of the changeover contact 6a consists of a protruded part 6a1 of a center impeller support type, while the upper contact part 6a2 consists of one of a cantilever support type.
