The present invention discloses a magnetic inductive non-contact load switch gear read-back device. The device comprises a rotation magnetic disk synchronously rotating with the middle axis of a loadswitch, a gear read-back disk configured to induct the change of a magnetic field on the rotation magnetic disk and a signal processing module configured to supply a working power supply for the gearread-back disk and transmit the read-back gear signals after being processed. The gear read-back disk and the rotation magnetic disk are opposite up and down and arranged in parallel, the gear read-back disk is fixedly arranged on the casing of the load switch; the rotation magnetic disk is embedded with a plurality of strong magnet sets corresponding to the gear positions, arranged according to BCD codes and arranged with the lifting of the gears in a clockwise direction, and the positions, corresponding to the position of the BCD code weight, on the gear read-back disk is provided with Hallsensors configured to induc
