Summary:The utility model provides a roller contact mechanism on a tapping switch to solve the problem that an existing switch is pressed on a static contact through a moving contact. When the switch is in running for a period of time, the contact is seriously burned. The roller contact mechanism is characterized in that the static contact is in a concave arc shape, a moving contact mechanism comprises a moving contact which is formed by same upper and lower barrels, an axis spring is placed in a cavity, the moving contact is placed in a concave part of a moving contact bracket, a connecting pin passes through a pin hole of the moving contact to install the moving contact on the moving contact bracket, the moving contact bracket is internally provided with two radial spring holes, each radial spring hole is internally provided with a radial spring which presses against an inner side of a connecting pin. The roller contact mechanism has the advantages that since the moving contact is a roller structure, mechanical wea
