Abstract
A device for controlling inductive load comprises at least: a power source, a first control assembly, a second control assembly and an inductive load. The first control assembly is connected in series to the power source, and comprises: a relay switch, a relay and a MOSFET, the relay switch is connected to a normal close contact and a normal open contact selectively. The normal open contact is electrically connected to the MOSFET, the normal close contact is connected to a drain terminal of the MOSFET, and a source terminal of the MOSFET is connected to the power source. The second control assembly is structurally similar to the first control assembly. The inductive load is disposed between the normal close contact of the relay switch and the normal close contact of the relay switch.
