ABSTRACT:
Each movable contact15is given a first force by a drive mechanism along a direction for bringing the movable contact into contact with a fixed contact5and given a second force through a leg14bby deformation of a supporting member14cresulted from an overtravel of the movable plate14. The fixed contact and the movable contact are arranged such that a resultant force of the first and the second forces acts in a direction normal to a contact surface defined between the fixed contacts and the movable contacts. So, a component force of the resultant force parallel to the contact surface is not generated, therefore, a side slip of the movable contact can be prevented when the contacts are opened or closed.
