Abstract
A rotatable one-piece lens assembly that may be rotated relative to the instrument housing comprising a lens boss, integral with the lens, moving with the rotated lens to move the pointer to engage and test the switches. After the switch test the lens may then be rotated back to its normal position. In this manner the switches are tested without removing the lens from the instrument housing.
