Abstract: The working principle and electrical performance of magnetic induction switch are studied,and a method of measuring the electrical performance of magnetic induction switch based on multi-purpose meter is proposed to measure the performance index of magnetic induction switch under no-load and loading conditions.The test verification shows that the electrical performance of magnetic switch can be effectively measured based on the multi-meter method，and the uncertainty of measurement results meets the requirements of the specifications of magnetic induction switch products.

Key words: Magnetic induction switch, Electrical properties, Measurement.
