Abstract: A high voltage air disconnect switch having an electrical load interrupter unit responsive to the opening of the high voltage air break disconnect switch. The electrical load interrupter unit including an actuating arm is contacted, during the opening of the switch, by a moving arc horn attached to and in electrical circuit with a switch blade of the high voltage air disconnect switch. The moving arc horn has operatively attached a spring catch which engages the actuating arm with a physical holding force applied to an electric contact point between the actuating arm and the moving arc horn to firmly capture the interrupter actuating arm against the moving arc horn during opening of the switch to prevent any arc burning damage due to arcing between the actuating arm and the moving arc horn as the switch opens.

Abstract: Systems of automatic transfer switches (ATS) are disclosed herein. One apparatus includes at least two automatic transfer switches coupled together. Each automatic transfer switches has contacts to couple a power source to a load. For each switch, an electromagnetic force biasing the contacts to each other is present if an electrical current flows through the switch. The automatic transfer switches may be on separate cassettes or on a single cassette. The power source of each switch may be the same or different.

Abstract: An automatic transfer switch includes a first conduction bar selectively coupled with a first power source and a load conduction bar; a second conduction bar selectively coupled with a second power source and the load conduction bar; a first blade assembly electrically coupled to the first conduction bar; and a second blade assembly electrically coupled to the second conduction bar. The first blade assembly is electrically coupled to a first source conduction bar in a closed position, and a first electromagnetic force induced by a first current flowing through the first blade assembly and the first conduction bar repulses the first blade assembly. The second blade assembly is electrically coupled to a second source conduction bar in a closed position, and a second electromagnetic force induced by a second current flowing through the second blade assembly and the second conduction bar repulses the second blade assembly.

Abstract: A cover for an electric switch assembly is disclosed in the present application. The cover includes connecting features that permit connection to a housing for the switch assembly in at least two locations. A first location is defined by a cover positioned to completely enclose all electrically conductive components in the switch assembly. A second location is defined by a cover positioned to enclose a portion of electrically conductive components and to permit access to a circuit associated with an open switch in the switch assembly.

Abstract: A switch includes connection elements, connectable via a switching contact whose movable contact area is formed on a movable contact element which bears against the stationary contact area in the closed position. In order to achieve a design with improved positional accuracy, an embodiment of the invention proposes that the two connection elements and the movable contact element each have a planar flat side and all flat sides lie in a common plane. In an embodiment, the connection elements are arranged on one side of the common plane and the movable contact element is arranged on the other side; a subarea of the flat side of one connection element forms the stationary contact area; a subarea of the flat side of the other connection element forms a planar bearing area; and the movable contact element with its flat side bears movably against the bearing area.
