A retractable control device for a household electrical appliance includes a knob movable against an elastic member within an aperture or seat of a control interface of the appliance. The knob is configured to assume two working positions including a first position in which the knob is seated in the aperture and a second position in which the knob extends outwardly therefrom. The knob cooperates with a control member for a functional element of the appliance, such as an electrical resistance heater or microwave generator of an oven, or a gas burner of a cooking hob. The device also includes a cylindrical element disposed and fixed in the aperture of the control interface about the knob. The cylindrical element contains the knob when the knob is in its first position and guides its movement within the aperture along a central longitudinal axis thereof.
A retractable control device for a household electrical appliance comprising, positioned on a control interface of said appliance, a pushbutton or knob movable against an elastic member within an aperture or seat of said interface, said knob being able to assume two working positions, in a first of which it is inserted in said aperture and in the second of which it is extracted therefrom, said knob cooperating with a control member for a functional element of said appliance, such as an electrical resistance heater or microwave generator of an oven, or a gas burner of a cooking hob, said control member being positioned below the interface, a cylindrical element being disposed and fixed in the aperture of this latter about the knob, characterized in that said cylindrical element contains the knob when this is in its first working position and guides its movement within the aperture along a central longitudinal axis thereof, said element also blocking oscillation of the pushbutton or knob in planes perpendicular to said axis.
