摘要： Automatic transfer switches and methods of forming such switches are disclosed herein. One automatic transfer switch disclosed herein includes a first source bar structured to connect to a first power source, a second source bar structured to connect to a second power source, and a stationary bar structured to be coupled to a load. The automatic transfer switch also includes a first movable bar and a second movable bar each electrically coupled and rotatably connected to the stationary bar. The length of each movable bar and the angle of each movable bar with respect to the stationary bus bar are selected to approximately balance the contact force on each movable bar. Thus, smooth and reliable operations of the automatic transfer switch can be achieved.
