Abstract
1404800 Vacuum cleaners NATIONAL UNION ELECTRIC CORP 13 Dec 1972 [30 Dec 1971] 57506/72 Heading A4F A control switch arrangement for controlling the operation of an electric motor M which drives the suction fan of an upright vacuum cleaner, comprises a manually actuated power switch 30 mounted in the grip of a handle pivotally connected to the housing of the cleaner, and a manually actuated combination motor speed and by-pass switch 31. With the switch 30 closed, requiring continual gripping by the operator, the switch 31 may be used in two positions, one resulting in a portion of windings 56a, 56b being activated, thereby resulting in a high fan speed, the other resulting in all the windings 56a, 56b being used, resulting in a lower fan speed. In a third position of the switch 31, the switch 30 is by-passed so as to enable the operator to release switch 30, fit an adapter to the suction outlet and use the cleaner for off-the-floor cleaning. In this third position, the motor M operates at a high speed. A lamp may be mounted on the housing for illuminating an area to be cleaned.
