ABSTRACT:
An angle switch device includes at least one MR element with a pinned layer and a free layer, and a magnet section. A relative angle between the magnet section and a lamination plane of the at least one MR element in a plane that contains a fixed magnetization direction of the at least one MR element and is perpendicular to the lamination plane of the at least one MR element is variable. The angle switch device provides a signal that represents whether the relative angle between the magnet section and the lamination plane of the at least one MR element is larger than or smaller than 90 degrees.
