<P>PROBLEM TO BE SOLVED: To provide a non-contact switch which can improve assemblability by reducing the number of components. <P>SOLUTION: A non-contact switch 1 comprises: a bias magnet 4 generating a bias magnetic field; a Hall element (semiconductor magnetic element) 3 arranged in the bias magnetic field generated by the bias magnet 4 for converting alteration of the bias magnetic field into an electric signal; a substrate 5 to which the Hall element 3 is electrically connected; terminals 8 to which the substrate 5 is electrically connected; and a resin terminal base 6 integrally holding the terminals 8. The non-contact switch 1 detects the bias magnetic field alteration caused by access of a detection object of a magnetic substance and outputs electric signals from the terminals 8. The terminal base 6 includes an element holding part 6A holding the Hall element 3, a magnet holding part 6B holding the bias magnet 4 and a substrate holding part 6C holding the substrate 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
