Abstract: The present invention relates to a multifunction switch for a vehicle and provides a multifunction switch for a vehicle in which a user may clearly and intuitively distinguish and recognize a rotating knob on a multifunction switch lever and an operating region of a corresponding rotation knob/mechanism which includes a symbol indicating a manipulating position of the rotating knob and which may enhance visibility that distinguishes respective operating regions of the multifunction switch lever and user convenience thereof. The multifunction switch includes a multifunction switch lever, a rotating knob mounted on the multifunction switch lever, and a lighting module for emitting light to the outside along an interface between a rotating knob operating region including a region where symbols indicating a rotating knob and an operating position of the rotating knob are marked and the rest of the operating regions adjacent to the rotating knob operating region.

Abstract: A backlight assembly with a light source unit, includes: a drive signal generator which generates a switching drive signal on the basis of a predetermined drive frequency and a feedback power fed back from the light source unit; a switching unit which outputs a power to the light source unit in response to the switching drive signal; and a controller which decreases the drive frequency if the feedback power is higher than a predetermined critical value.

Abstract: A vacuum cleaner is provided. The vacuum cleaner includes a first suction unit, a main body, a second suction unit, a connection flow-tube, and a flow-passage switching device. The main body communicates with the first suction unit and includes a suction motor to generate a suction force. The second suction unit is configured to be selectively attached to the main body. The connection flow-tube is configured to selectively connect the first suction unit or the second suction unit to the suction motor. The flow-passage switching device is configured to connect the connection flow-tube to the first section unit or the second suction unit according to a disposition state of the second suction unit.
