摘要： A contactless switching apparatus wherein a magnetic-containing casing with poles located at both ends and a central space extending along the length of the casing is provided. A bar magnet is positioned in the space of the casing so that the bar magnet can be slidably moved within the casing. A galvanomagnetro effect device is provided at at least one of the poles of the casing or on the bar magnet; the device being positioned in the central space and either fixed at the internal surface of the polar portion of the casing, or being capable of alignment with said internal surface. The switching apparatus is designed so that the device functions when the polar portion of the bar magnet, the polarity of which is opposite to the polarity of the magnet of casing, is opposed to the polar portion of the casing.
