    • A portable hand-held vacuum cleaner includes a housing for holding a motor and a suction fan and a switch slidably mounted on the housing for selectively activating the motor. The switch extends out of the housing so as to be manually engageable. A nozzle is mounted on the housing and a release button, pivotally mounted on the housing, selectively releases the nozzle from the housing. The release button includes a first finger which engages an aperture in a wall of the nozzle, a pivot aperture through which extends a pivot pin secured to the housing for enabling the release button to move between a pair of end positions and a biasing element for urging the release button to one of the pair of end positions. A second finger is also provided on the release button. In one of the end positions of the release button, the second finger engages in a recess of the switch to prevent the release button from being pivoted. In another of the end positions of the release button, the second finger engages the switch to prevent the switch from being slid.
