<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 bias magnetic field alteration into an electric signal; a substrate 5 to which the Hall element 3 is electrically connected; and terminals 9, 11 to which the substrate 5 is electrically connected. 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 11 via the substrate 5. The non-contact switch 1 further comprises a resin holding member 6 holding the Hall element 3, the bias magnet 4 and the substrate 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
