| 摘要 | A magnetic type switch may include a magnet having a magnetic pole face arranged to face a magnetic body provided in an object. A change in magnetic field due to a change in distance between the magnetic body and the magnet by an operation of the object may be detected to output a signal for indicating at lease one of a presence and an absence of the operation of the object. The switch may also include a casing in which the magnet may be disposed, where the casing may have a facing part between the magnet pole face of the magnet and the magnetic body. The switch may further include a protector member formed of a non-magnetic body having a predetermined thickness in a direction vertical to the magnetic pole face, where the protector member maybe attached to the casing to cover at least the facing part. | ||||||
