Abstract: A mounting assembly is for an electrical switch, such as for example, a dimmer switch, which includes a heat sink. The mounting assembly includes a switching member, an insulator disposed between the switching member and the heat sink, and a separate cover member overlaying the switching member. The separate cover member is structured to secure the switching member and the insulator to the heat sink. The switching member includes a switch body and a conductive tab. The separate cover member secures the switching member to the heat sink, without requiring a separate fastener to be inserted through a hole in the conductive tab. The insulator electrically isolates the conductive tab from the heat sink.

Abstract: This disclosure describes examples of an apparatus to enclose components of a switching assembly of an automatic transfer switch. In one embodiment, the apparatus, or arc chamber cover, has a housing made of material with optical properties that permit observation of the interior of the housing. A mounting assembly couples to the housing. The mounting assembly secures the apparatus to the automatic transfer switch. In one example, the mounting assembly comprises feet comprising a material with mechanical properties that can withstand pressure and other forces inside of the interior chamber. The apparatus also includes one or more baffles to control the flow of gasses and control electric arcs within the switching assembly.

Abstract: In a system with two electronic panels arranged with a plurality of busses between them, the removal of one of the electronic panels exposes the live busses to a user. To shield the user from the exposed busses, a mechanism operates shutters to close and cover the busses. The mechanism operation can be based on the rotation of a cam supporting the shutters in the open position. A manual override allows the shutters to be kept in the open position even when the busses are exposed due to the removal of an electronic panel.
