Abstract:
     The device uses a quill, driving gear, drive gear, rolling element and roller. When switching, the sliding friction between the moving and fixed contacts is converted into rolling friction between the rolling element and the roller, so that the switch life is increased four times and it is small, light, simple and easy to maintain. At the same time, there is not any braze filings in the transformer produced by wearing between the contacts, so that the insulation of the oil isn't reduced and the transformer can run safely for long. The invention is used in electric power, electric stove and other transformers.
