A handle assembly includes a stationary handle having a first switch, a second switch, and a movable handle coupled thereto. The second switch is movable between a first position and a second position. The movable handle is movable relative to the stationary handle between a spaced position and an approximated position, in which the movable handle actuates the first switch. A portion of the movable handle is configured to contact the second switch when the second switch is in the first position to prevent the movable handle from actuating the first switch.
