Electrical device housing with protrusions to maintain a consistent gap between a floating mechanical actuator and housing aperture

An electrical device comprising:

• a housing including a front surface, the front surface having an aperture formed therein;
• a line terminal disposed at least partially within the housing, the line terminal configured to be electrically coupled to an alternating current (AC) power source;
• a load terminal disposed at least partially within the housing, the load terminal configured to be coupled to an electrical load;
• a switching circuit including a controllably conductive switch in series electrical connection between the line terminal and the load terminal, wherein the controllably conductive switch is configured to alter an electrical characteristic of power delivered to the electric load;
• a switch in electrical communication with the switching circuit, the switch configured to be mechanically engaged and to communicate a switching signal to the switching circuit;
• and
• a floating mechanical actuator moveable between a rest position and a depressed position, the mechanical actuator being user accessible via the aperture, wherein the mechanical actuator is arranged and configured to mechanically engage the switch in the depressed position;
• wherein when the switch is engaged by the mechanical actuator, the switching circuit controls the controllably conductive switch to alter the electrical characteristic of the power delivered to the electric load;
• and
• wherein the housing includes a plurality of protrusions protruding into the aperture, the plurality of protrusions arranged at a plurality of locations along an inner surface of the aperture and configured to contact the mechanical actuator in at least the rest position such that a consistent gap between an outer perimeter of the mechanical actuator and the inner surface of the aperture is maintained.
