A control panel assembly of a cleaning device is provided to prevent buttons from being constrained or defectively operated while the buttons are pressed. A control panel assembly of a cleaning device comprises: a tact switch mounted at a PCB(Printed Circuit Baseboard) and formed with a pressing unit; a button(110) disposed on a control panel to be pressed and projected of a rack(130) pressing the tact switch; and a stopper(135) formed at one of the rack and the pressing unit so as to prevent the rack and the pressing unit from being across each other and to hold one of the rack and the pressing unit. The rack of the button has a hook-cross section, and the stopper is protruded from one end of the rack. The rack of the button is formed with a cross unit(130a) having a cross-like section; and four protrusion units(130b) projected vertically from an end of the cross unit. The stopper is a rib more projected and elongated than the cross unit from the protrusion unit. |
