VACUUM CLEANER WITH SWINGING CONTROL ELEMENT Russian patent published in 2009 - IPC A47L9/28 

FIELD: instrument making.

SUBSTANCE: swinging element of control is designed for switching by means of switch of different functions of electric instrument, in particular, vacuum cleaner. Control element is arranged in the form of a plate and is installed in bearings on electric instrument with the possibility of rotation in axis in direction of switch actuation. Control element has a slider with working surface, which for control of vacuum cleaner parametre has possibility of displacement according to moving track provided in control element. Slider moving track is installed parallel to the axis of control element rotation and higher than it. Moving track of slider and axis of rotation are installed in single plane, in which normal line is lying to working surface of slider. Due to parallelism of rotation axis of control element and moving track, length of force arm applied to working surface of slider, relative to axis of control element rotation preserves permanent value at any position of slider.

EFFECT: by setting such constant arm of force possibility is provided for especially reliable compliance between slider and plate of control element.
