PROBLEM TO BE SOLVED: To provide a relatively compact non-contact switch.SOLUTION: There is provided a non-contact switch 100 including: a hall IC 10 converting a magnetic field to an electric signal and outputting the electrical signal; one or two or more magnets 30 generating the magnetic field; and a resin 40 confining the magnet 30 and the hall IC 10 therein, and positioning the hall IC 10 such that the hall IC is positioned in an extension direction of the boundary between the S pole and the N pole of the magnet 30. When a magnetic body 200 comes close to the hall IC 10, the output of the hall IC 10 is switched from ON to OFF by the change of polarity of a magnetic field from the magnet 30.SELECTED DRAWING: Figure 2 |
