Magnetic proximity switch is one of the non-contact electric switches, Comparing with conventional mechanical switches, it offers many advantages, Its operational principle is to change electromagnetic quantity into desired electrical signal. Based on studying the principle of magnetic-resistive sensor, a magnetic proximity switch was designed by adopting the magnetic-resistive sensor. The functions of position sensing and switching were achieved. Its good effects are obtained in experiment. Its features of non-contact, non-wear-out, long operation life and quick response have excellent applicable prospects.
