  • Patent number: 6541718
    Abstract: A full power switch assembly for a portable generator that is capable of instantly communicating the presence and operation of a full power switch to the user is disclosed. The full power switch assembly includes a first outlet for supplying electrical power having a first voltage (e.g., 120 VAC), a second outlet for supplying electrical power having a second voltage (e.g., 240 VAC), and a switch including a selector. The selector is movable from a first position to a second position for causing the first outlet to be capable of supplying electrical power up to a maximum power level. Movement of the selector between the first position and the second position further causes indicia to be displayed for indicating whether the first outlet is capable of supplying electrical power up to the maximum power level.
