Common Household Light Switches

[2011FRC0263]

Is the assumption that a Common Household Light Switch is one that would be mounted in an outlet box and not a toggle switch mounted on a lamp correct?

If it is a wall switch, may it be modified in any way?
e.g. removal, cutting or bending of the metal mounting / grounding plate
or removing any other material for weight saving.

Thank you

For the purposes of the 2011 competition, a common household light switch is any electrical switch that would normally be mounted in a wall outlet box with household wiring, typically available at a home supply center (e.g. Lowes or Home Depot).

Minor modifications of the switch (e.g. removing the mounting tabs) are permitted, as long as the basic structural integrity and overall safety of the switch are not compromised.
