Abstract
The present invention is directed to a unique device for mounting electrical apparatus to a wall panel, wherein the device includes a main body portion having a cavity for holding components of the electrical apparatus and a pillar-shaped portion attached to the main body portion and extending through an opening in the wall panel. A free end of the pillar-shaped portion includes a plurality of outwardly protruding steps which overlap the wall panel, with a first set of the steps having a first axial length and a second set of the steps having a second, shorter axial length. A biasing member extends between the main body portion and the wall panel and biases the wall panel into contact with only the first set of steps, creating a gap between the wall panel and the second set of steps. A cover member surrounds the free end of the pillar-shaped portion and extends into the gap, with the second set of steps biasing the cover into contact with the wall panel.
