Abstract
Each movable contactis given a first force by a drive mechanism along a direction for bringing the movable contact into contact with a fixed contactand given a second force through a legby deformation of a supporting memberresulted from an overtravel of the movable plate. 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.
