Abstract
A magnetic element switch is provided which can reduce the number of parts and the cost of the switch as well as improve the reliability thereof. The magnetic element switch includes an operation part oscillatable about a neutral position when operated by an operator, a magnet oscillatable about a neutral position directly or indirectly due to the oscillation of the operation part, and a magnetic element fixedly disposed adjacent to the magnet for generating an electromotive voltage proportional to the density of a magnetic flux incident thereon. The magnetic element is positioned such that a magnetic force line generated by the magnet at the neutral position is allowed to pass through the magnetic element parallel to an electric field formed with the magnetic element and also such that, when the magnet is oscillated, the magnetic force line is allowed to pass therethrough not parallel to the electric field within the magnetic element. The magnetic element switch is operated based on an electromotive voltage having a plurality of values generated by the magnetic element at a plurality of predetermined oscillation positions of the magnet.
