Provided is a magnetism increasing structure of an isolating switch. The isolating switch mainly solves the problem of high cost caused by the adoption of a high-magnetism permanent magnet in the existing isolating switch. The motor is characterized by further comprising at least one pair of magnet assemblies (4) which are oppositely arranged, each magnet assembly comprises permanent magnets (41) and a magnetism increasing plate (42), N poles of the permanent magnets in pairs are oppositely arranged, and the magnetism increasing plates are arranged on the backs of the permanent magnets. According to the magnetism increasing structure of the isolation switch provided by the utility model, the N-pole magnetism is enhanced, the arc extinguishing speed is improved, the S-pole magnetism is weakened at the same time, metal particles are prevented from being attached to the surface of a product shell when the product is applied, and the insulation performance grade of the shell is improved. 隔离开关的增磁结构。主要解决目前的隔离开关采用高磁
