Summary:A housing assembly and a support rail and extension rail assembly for an electrical switching apparatus includes various components. The support rail assembly is, preferably, a cast plate-like body wherein selected components, such as a levering in mechanism lug and support rails are formed as part of the casting. The extension rail assembly includes a generally flat, elongated body having a finger notch that is sized to accommodate a gloved hand and a mounting slot. The extension rail assembly is coupled to the support rail assembly by a pivotal mounting that extends through the mounting slot. The extension rail further includes a lateral extension. The housing assembly includes an L-shaped cutout having a horizontal portion and a descending vertical portion. When the extension rail is in a storage, or first, position, the lateral extension is disposed in the L-shaped cutout.
